COVID-19 and influenza vaccine hesitancy among college students

Factors Influencing COVID-19 Vaccination Hesitancy and Booster Dose Adherence Among University Students: A Cross-Sectional Study in Crete, Greece

Background/Objectives: Vaccination hesitancy remains a global challenge, especially after the COVID-19 pandemic. We aimed to assess the prevalence of hesitancy towards regular COVID-19 vaccinations, including booster doses (additional doses beyond the primary to sustain or improve immunity), among university students and its associated factors. Methods: We conducted a cross-sectional study involving 190 university students from Hellenic Mediterranean University in Crete, Greece. Data were collected through an electronic survey distributed from July to October 2024. The survey included socio-demographic characteristics, health status factors, prior COVID-19 infection and vaccination history (general and for COVID-19), attitudes about COVID-19 vaccination, and the Attitude Towards Adult Vaccination (ATAVAC) scale. Qualitative data were also collected by addressing themes regarding ways to overcome vaccine hesitancy. Results: The study found that 64% of participants expressed hesitancy towards receiving COVID-19 booster doses. Factors contributing to this hesitancy were female gender, current smoking, pregnancy, concerns about vaccine side effects, a lack of confidence in vaccine efficacy, COVID-19 infection history, low perceived susceptibility to infection, and reliance on media information. Additionally, increased trust in the value of adult vaccination, adhering to recommendations of treating physician/scientist opinions, and prior adherence to vaccination were positively associated with regular COVID-19 vaccinations. A thematic analysis of the qualitative data identified four key strategies to overcome student vaccine hesitancy: enhancing health literacy, validating vaccine safety through further research, alleviating pandemic-related fears, and addressing distrust in authorities and opposition to mandatory vaccination. Conclusions: Our findings provide insights into the intricate factors and barriers of COVID-19 vaccination hesitancy among university students, thus emphasizing the need for more targeted interventions.

COVID-19 knowledge, attitudes, and behaviors of STEM vs. non-STEM college students in Central Appalachia in 2021, a student-led project

Background: The COVID-19 pandemic has provided the general public with an understanding of scientific processes and health systems surrounding vaccination in real-time. This report assesses responses of college students in a regional university to the Centers for Disease Control and Prevention's (CDC) Knowledge, Attitudes, and Behaviors (KAB) survey in the spring of 2021. Methods: Participants were categorized based on study major: Science, Technology, Engineering and Math (STEM), non-STEM, or health science disciplines. Chi-square tests were used to compare vaccination beliefs between groups. Results: 632 respondents were included in the final analysis. STEM students were the least likely to agree that vaccinated individuals should not need masks (21%) compared to non-STEM (42%) and health science majors (37%). 51%, 45%, and 35% of STEM, non-STEM, and health science students were vaccinated respectively. No statistically significant differences were noted between groups. Conclusions: Vaccine hesitancy was similar in all students. Area of study did not impact vaccine behaviors.

Using "pop-up" clinics and live-attenuated influenza vaccine to reduce barriers to flu vaccination among college students

Background: College students have cited inconvenience, ease of forgetting, and lack of time as barriers to influenza (flu) vaccine receipt. We hypothesized that "pop-up" clinics and live-attenuated influenza vaccine (LAIV) would facilitate delivery and align with preferences of college students. Methods: During the 2023-2024 flu season, undergraduate participants were recruited to receive LAIV at 5 "pop-up" clinics across a large midwestern campus. Individuals who received LAIV were approached to complete a Likert-scale survey asking about their experience. Results: Across all clinics, 337 individuals received LAIV and 129 completed the survey. Respondents reported that "pop-up" clinics decreased barriers to vaccination. Regarding LAIV acceptance, 44.2% noted a preference for LAIV while 46.5% noted no preference between intranasal and injectable vaccines. Importantly, over 27% of students stated they would not have received vaccine without this "pop-up" clinic option. Conclusion(s): "Pop-up" clinics and LAIV effectively alleviate barriers to facilitate flu vaccination for college students.

Vaccination uptake is influenced by many cues during health information seeking online

BACKGROUND

Much government response to improving vaccination uptake during the COVID-19 pandemic has focused on the problems of misinformation and disinformation. There may, however, be other signals within online health information that influence uptake of vaccination.

OBJECTIVE

This study identified the influence of various health information signals within online information communities on the intention of receiving the vaccine.

METHOD

A deductive approach was used to derive constructs from signalling theory. Constructs were validated by a convenience sample using a questionnaire. Structural equation modelling (SEM) was used to evaluate the measurement model, the structural model and the multigroup analysis.

RESULTS

The analysis showed a significant impact of signals derived from past experience, information asymmetry and source credibility constructs on the perceived quality of the vaccine service. The perceived quality also had a significant impact on the intention to receive the vaccine.

DISCUSSION

Signalling theory was able to explain the importance of health information signals perceived from online platforms on the intention of individuals to receive the vaccine.

CONCLUSION

Information asymmetry between information provider and receiver, perceived credibility of sources and perceived quality of the vaccination service may influence decisions about vaccination.

Correlates of and barriers to COVID-19 vaccine initiation and intention among US college students

OBJECTIVE

To examine correlates of and barriers to COVID-19 vaccine initiation and intention among college students.

PARTICIPANTS

1,171 students attending a public university in the South.

METHODS

Multivariate logistic regression was used to assess the correlates of vaccine intention and initiation. Reasons for pursuing or foregoing vaccination were analyzed qualitatively using an inductive approach.

RESULTS

Among respondents, 44% had initiated vaccination, 38% intended to be vaccinated, and 18% were unsure about/unwilling to be vaccinated. Vaccine initiation and intention were both associated with 2019-2020 seasonal flu vaccination and political ideology, with conservative-leaning students having lower odds of vaccine initiation and of intention relative to liberal-leaning students. The most common reasons for vaccine initiation/intention and for vaccine hesitancy differed in frequency by political ideology.

CONCLUSION

The most effective vaccine promotion strategies may be those tailored to different social groups, virus-related beliefs/perceptions, and the specific concerns of vaccine hesitant students.

Impact of COVID-19 on vaccine confidence and uptake: A systematic literature review

During the coronavirus disease 2019 (COVID-19) pandemic, scheduled vaccinations were postponed, mass vaccination programmes were suspended and opportunities for healthcare workers to administer vaccines ad hoc decreased. The aims of this systematic literature review were to determine the impact of the COVID-19 pandemic on vaccine confidence, intent and uptake in preexisting routine childhood or adult vaccination programmes, and to identify factors associated with changes in acceptance, intent and uptake of preexisting vaccines. Medline and Embase were searched for studies in Australia, Brazil, Canada, China, Japan, the USA, and European countries, published between 1 January 2021 and 4 August 2022. A complementary gray literature search was conducted between 11 and 13 October 2022, and supplemented with additional gray research in October 2023. In total, 54 citations were included in the review. Study design and geography were heterogeneous. The number of adults who received or intended to receive an influenza or pneumococcal vaccine was higher during the pandemic than in previous seasons (n = 28 studies). In addition, increased acceptance of adult vaccinations was observed during 2020-21 compared with 2019-20 (n = 12 studies). The rates of childhood vaccinations decreased during the COVID-19 pandemic across several countries (n = 11 studies). Factors associated with changes in intention to receive a vaccination, or uptake of influenza vaccine, included previous vaccination, older age, higher perceived risk of contracting COVID-19, anxiety regarding the pandemic and fear of contracting COVID-19. Acceptance and uptake of influenza and pneumococcal vaccines generally increased after onset of the COVID-19 pandemic.

A cross-sectional investigation of factors influencing mpox vaccine hesitancy for students in Southwest China

From July to September 2023, China reported over 1, 400 confirmed cases of mpox transmitted mainly through sexual contact between males. Meanwhile, the percentage of men who have sex with men at universities in southwestern China is increasing every year, which is likely to lead to a potential spread of mpox on campuses. Vaccination is an effective preventive measure against infectious diseases, this study examined the willingness of university students in Southwest China to receive the mpox vaccine and analyzed the factors influencing their decision. A cross-sectional survey was conducted among 7311 university students from 10 universities in Southwest China between August 13 and September 1, 2023. The survey revealed a hesitancy rate of 56.13% toward the mpox vaccine, with the most common reason being concerns about vaccine safety (1407/4104, 34.29%). Univariate analysis identified 13 variables that significantly differed between the vaccine acceptance and vaccine hesitancy groups. Multivariate logistic regression analyses indicated protective factors for vaccine hesitancy, such as sexually transmitted diseases, previous knowledge about mpox, frequent information about mpox, people can get reinfection of mpox, and worries about mpox endemic in China. Additionally, the confidence and convenience dimensions in the 3Cs model were identified as risk factors for mpox vaccine hesitancy. This study found a high rate of vaccine hesitancy among university students in Southwest China regarding the mpox vaccine. Collaboration between university and healthcare departments is recommended to address mpox vaccine hesitancy among college students, thereby promoting their willingness to receive the mpox vaccine.

Perceptions of vaccine requirements among students at four Pennsylvania universities

BACKGROUND

University students have a unique perspective on vaccination because of their recent or perhaps newly acquired autonomy and ability to make health-related decisions. The development of the COVID-19 vaccine in 2020 and its implementation over the past few years was accompanied by much information and communication about vaccination requirements and safety, which may have affected students' perspectives on vaccination and vaccine requirements more broadly. This analysis describes current vaccine policies at several universities and evaluates student respondents' perceptions of and agreement with university vaccine requirements.

METHODS

A 32-question survey was administered to undergraduate, graduate, and professional students attending four Pennsylvania universities in March-May 2023; 2,223 students responded to the survey. The survey included questions about vaccine requirements, agreement with vaccine requirements, and knowledge of selected vaccines. These responses were compared with the actual vaccine requirements and recommendations of the four universities.

RESULTS

Most respondents agreed with university vaccine requirements, though knowledge of those requirements varied, with many unaware of which were required. University requirement of the COVID-19 vaccine was not associated with being vaccinated for COVID-19. However, while the requirement itself was not related to vaccine uptake, respondents' perception of a requirement was. Respondents were more likely to report COVID-19 vaccination and influenza vaccination if they believed their university required those vaccines. Respondents were more likely to approve of a vaccine requirement if their perception was that their university required that vaccine.

CONCLUSIONS

Overall, student respondents were supportive of their institution's vaccine requirements, but many lacked information about those requirements. Clear messaging using multiple modes of communication about vaccines and vaccine requirements may improve students' knowledge of vaccines and result in a corresponding increase in vaccine uptake.

A scoping review of COVID-19 vaccine hesitancy: refusal rate, associated factors, and strategies to reduce

Objective

This study aimed to investigate the evidence regarding vaccine hesitancy including refusal rate, associated factors, and potential strategies to reduce it.

Methods

This is a scoping review. Three main databases such as PubMed, Scopus, and Web of Science were searched from 1 January 2020 to 1 January 2023. All original studies in the English language that investigated one of our domains (vaccine hesitancy rate, factors associated with vaccine hesitancy, and the ways/interventions to overcome or decrease vaccine hesitancy) among the general population were included in this study. The data were charted using tables and figures. In addition, a content analysis was conducted using the 3C model of vaccine hesitancy (Confidence, Complacency, and Convenience) that was previously introduced by the WHO.

Results

Finally, 184 studies were included in this review. Of these, 165, 181, and 124 studies reported the vaccine hesitancy rate, associated factors, and interventions to reduce or overcome vaccine hesitancy, respectively. Factors affecting the hesitancy rate were categorized into 4 themes and 18 sub-themes (contextual factors, confidence barriers, complacency barriers, and convenience barriers).

Conclusion

Vaccine hesitancy (VH) rate and the factors affecting it are different according to different populations, contexts, and data collection tools that need to be investigated in specific populations and contexts. The need to conduct studies at the national and international levels regarding the reasons for vaccine refusal, the factors affecting it, and ways to deal with it still remains. Designing a comprehensive tool will facilitate comparisons between different populations and different locations.

A unified framework is employed to describe the models, emphasizing their integration with epidemiological models to facilitate a holistic understanding. This article also summarizes evolving nature of literature, relevant research gaps, and authors' perspectives for model selection. Finally, future research scopes are detailed both in the context of modeling and solutions approaches.

Evaluation of vaccine perceptions in Israel's Elderly: A Comparative study of COVID-19 and influenza vaccination attitudes

Purpose

This study aimed to evaluate the attitudes of Israeli elderly population towards COVID-19 and influenza vaccines, and to assess factors contributing to these attitudes.

Methods

Four-hundred and one participants exhibiting symptoms consistent with COVID-19 or influenza were enrolled and filled out a questionnaire. A second questionnaire was filled out for hospitalized patients at discharge. Nasopharyngeal samples were collected and detected for COVID-19 and influenza presence by reverse transcription PCR. Participants were divided into 3 groups according to their attitude towards vaccine- Pro-vaccine, Anti-vaccine and Dependent group, which represented participants whose stance depended on disease infection rate.

Results

Out of 401 participants, 11.2% (45/401) tested positive for COVID-19, 10.5% (42/401) were positive for Influenza A and one (0.2%) patient had Influenza B. The participants expressed varied beliefs about COVID-19 vaccine: 14.7% (59/401) agreed that it causes disease, 25.4% (102/401) doubted vaccine effectiveness and 22.9% (92/401) questioned vaccine safety. A higher percentage of individuals in Pro-Vaccine group (66.3%, 179/270) as compared to Anti-Vaccine (45.3%, 24/53) and to Dependent (60.3%, 47/78) groups had a COVID-19 history. Hospitalization history was significantly more common in Pro-Vaccine (11.1%, 30/270) and Dependent groups (16.7%, 13/78) than in Anti-Vaccine group (1.9%, 1/53).Influenza vaccine effectiveness was doubted by 19.7% (79/401), 18% (72/401) participants questioned safety, and 18.7% (75/401) agreed that the vaccine causes disease. The majority of both Dependent (54.2%, 13/24) and Pro-Vaccine (56.2%, 167/297) groups believed they received sufficient information about the vaccine, while only 25% (20/80) of the Anti-Vaccine group has similar impressions.

Conclusions

This analysis reveals a notable disinclination towards vaccination among some of the elderly, reflecting their deep and ingrained hesitancy. These findings emphasize the need for customized approaches to improve vaccine acceptance in this vulnerable group. Such strategies should consider the various motivations and influences shaping elderly perspectives, from individual health experiences to wider social and cultural factors.

Impact of prior SARS-CoV-2 infection on college students' hesitancy to receive additional COVID-19 vaccine booster doses: A study from Taizhou, China

PURPOSE

This study aimed to examine the impact of a history of SARS-CoV-2 infection on the hesitancy of college students to receive additional COVID-19 vaccine booster doses.

METHODS

A population-based self-administered online survey was conducted in July 2024 in Taizhou, China. A total of 792 respondents were included in this study. Logistic regression was conducted to identify factors associated with college students' hesitation to receive booster doses of the COVID-19 vaccine.

RESULTS

Of 792 respondents, 32.2 % hesitated to receive additional doses of the COVID-19 vaccine booster. Furthermore, 23.5 % of the respondents reported an increase in hesitancy to receiving additional COVID-19 vaccine booster doses compared to before they were infected with SARS-CoV-2. In the regression analyses, college students who had a secondary infection were more hesitant to receive additional COVID-19 vaccine booster doses (OR = 0.481, 95 % CI: (0.299-0.774), P = 0.003). Moreover, students with secondary infections who were male (OR = 0.417, 95 % CI: 0.221-0.784, P = 0.007), with lower than a bachelor's degree (OR = 0.471, 95 % CI: 0.272-0.815, P = 0.007), in non-medical majors (OR = 0.460, 95 % CI: 0.248-0.856, P = 0.014), and sophomores or below (OR = 0.483, 95 % CI: 0.286-0.817, P = 0.007) were more hesitant to receive additional COVID-19 vaccine booster doses.

CONCLUSION

A history of SARS-CoV-2 infection affects college students' hesitation to receive additional COVID-19 vaccine booster doses, which was higher in those who experienced secondary infections.

Vaccine Hesitancy in Israel: Exploring the Relationships with Vaccination History, Knowledge, and Attitudes towards Influenza Vaccines

Influenza vaccination is a highly effective strategy for mitigating all the repercussions of influenza infections. Despite the potential severity of influenza and the accessibility of secure vaccinations, worldwide rates of influenza vaccination continue to be low, particularly among students. This study examines the correlative relationships between influenza vaccine history, knowledge, attitudes toward influenza vaccines, and vaccine hesitancy among college students. To that end, we used an online questionnaire to conduct a cross-sectional study encompassing 610 students. A significant majority of participants reported having experienced influenza (82%), with slightly more than half having received influenza vaccinations in the past (57%). With respect to the current research year, health sciences students exhibited a higher likelihood of either having been vaccinated or intending to receive the vaccine than did their counterparts. Among students who had been vaccinated previously, approximately one-fifth opted for vaccination in the present year (21%). Similarly, 22% of the students whose parents were vaccinated chose to get vaccinated this year. Notable disparities in knowledge about influenza vaccines were observed across various departments, with health sciences students demonstrating the highest levels of awareness. Moreover, a negative relationship was found between knowledge, attitudes, and vaccine hesitancy. These results suggest that targeted lectures by professionals emphasizing vaccine safety and university-hosted events addressing this subject in collaboration with the Ministry of Health, incorporating influenza vaccination stations, could be instrumental in bolstering the vaccination rate.

The association between influenza vaccination and the perception of COVID-19 as well as COVID-19 vaccination behavior among community residents in Anhui province, China

Influenza is a significant public health threat associated with high morbidity and mortality globally. This study investigated the influenza vaccination rate (IVR) among community residents in Anhui province, China, and explored the association between participants' influenza vaccination and their key sociodemographic characteristics, perception of COVID-19 as well as COVID-19 vaccination behavior. We found that the IVR among respondents in Anhui province was 27.85% in 2020. Regression analyses revealed that males (OR = 1.41, 95% CI: 1.01 ~ 1.96), residents with above middle school education (OR = 1.88, 95% CI: 1.04 ~ 3.39), considered themselves likely to be infected with COVID-19 (OR = 1.53, 95% CI: 1.04 ~ 2.24), had received the COVID-19 vaccine (OR = 9.85, 95% CI: 3.49 ~ 27.78), did not plan to receive COVID-19 vaccine in the future (OR = 1.70, 95% CI: 1.17 ~ 2.47), and had no adverse reactions after COVID-19 vaccination (OR = 1.54, 95% CI: 1.04 ~ 2.27) were associated with a higher IVR. The acceptance of influenza vaccination was mainly associated with respondents' gender, education, perception of COVID-19, history of COVID-19 vaccination in city and countryside community residents in Anhui province.

Cross-sectional study of factors related to COVID-19 vaccination uptake among university healthcare students

Introduction

Healthcare students are more likely to become infected than other university students as they may encounter patients with COVID-19 during clinical training. Vaccination uptake is essential to prevent infection. This study explored factors related to COVID-19 vaccination uptake among healthcare students.

Methods

This cross-sectional study conducted online surveys of undergraduate and graduate nursing and healthcare graduate students from four medical universities in the Tokyo Metropolitan Area of Japan. Data were collected from June to August 2022, when the fourth vaccination program was initiated.

Results

Data from 1,169 students were analyzed (response rate = 37.3%). The mean age was 25.1 ± 7.6 years, and most were female (82.3%). Academic majors included nursing (68.0%), medicine (16.3%), dentistry (9.3%), and others (6.4%). Thirty students (2.6%) were not vaccinated, one student (0.1%) had received one vaccination, 997 (85.3%) had received three, and 27 (2.3%) had received four. The major reason for not being vaccinated was insufficient confirmation of its safety (n = 25). Students who had received at least one vaccination (n = 1,139), 965 (84.7%) reported experiencing adverse side effects, the most frequent being pain at the injection site (76.2%), followed by fever (68.3%). In the logistic regression, a greater number of vaccinations (3-4 times) was associated with older age (odds ratio, OR = 1.53), working (OR = 1.67), and more frequent infection-preventive behaviors (OR = 1.05). Significantly fewer students were vaccinated at University B than at University A (OR = 0.46). Additionally, those majoring in subjects other than nursing (OR = 0.28), and students from non-Asian countries (OR = 0.30) were less likely to be vaccinated.

Discussion

It is necessary to pay attention to and encourage the vaccination of students who engage in low levels of preventive behavior, students who are young, international, or unemployed, and those in non-healthcare professional majors.

Factors associated with COVID-19 vaccination status: A cross-sectional study of California students in higher education

To examine the factors associated with coronavirus vaccine hesitancy among students in higher education, we conducted a cross-sectional mixed-methods study between June and August 2021 among California students in higher education (n = 4444). We collected information on vaccination status, socio-demographics, and attitudes towards coronavirus vaccination. After adjusting for social demographics and social network characteristics, compared to those with household members who were vaccinated, those who had household members who were unvaccinated had 0.11 (95% CI 0.09 - 0.14) times the odds of being vaccinated. Political identification was related to vaccination status: compared to those who did not identify with any particular party, those who identified as progressive had 12.5 (95% CI 3.70 - 50.0) times the odds of being vaccinated. Asians had higher odds (OR = 1.54; 95% CI 1.08 - 2.04) of being vaccinated compared to whites and men were marginally less likely to be vaccinated (OR = 0.79; 95% CI 0.61 - 1.00). However, age, parental education, and educational status were unrelated to vaccination status. Social and demographic factors may be associated with the decision to remain vaccinated among young adults. Public health messages should utilize social networks to encourage vaccination uptake among young adults.

The Association between Levels of Trust in the Healthcare System and Influenza Vaccine Hesitancy among College Students in Israel

Influenza is a contagious respiratory disease caused by the influenza virus. Vaccination proves an effective approach to preventing influenza and minimizing the risk of experiencing associated complications. However, the influenza vaccine coverage rate among Israeli college students is low due to a sense of complacency, lack of knowledge, and vaccine hesitancy. The current study examined the relationship between the level of trust in the healthcare system and influenza vaccine hesitancy among college students in Israel. This cross-sectional study was conducted via an online questionnaire in April-May 2023. In total, 610 students were surveyed, of whom 57% had been vaccinated against influenza in the past; however, only 12% were vaccinated this year. Negative, significant, and moderate relationships were found between the level of trust in the healthcare system and influenza vaccine hesitancy. Students who had been vaccinated in the past had a higher level of trust in the healthcare system and a lower level of vaccination hesitancy. The linear regression model revealed that the variables of being a woman, not Jewish, vaccinated, and trusting the Ministry of Health, family doctor, and health professionals were associated with a decrease in vaccine hesitancy. These findings are in line with previous research in the field. Based on the present results, it may be advisable to develop intervention programs aimed at increasing confidence in the healthcare system and vaccinations by providing knowledge and addressing students' concerns regarding vaccination.

Flu vaccination coverage in Italy in the COVID-19 era: A fuzzy functional k-means (FFKM) approach

BACKGROUND

In Europe, flu vaccination coverage has decreased, and there are complex barriers to overcome to vaccinate against flu. Many studies have been conducted to estimate vaccination coverage. The COVID-19 pandemic threatens to disrupt immunization programs in many countries, including Italy, where vaccination against the flu is recommended but not mandatory. This paper aims to understand changes in flu vaccine uptake in Italian regions.

METHODS

Using functional data analysis and fuzzy functional k-means clustering, we investigated changes in flu vaccine coverage in Italian regions before (2010-2019) and after (2020-2022) the COVID-19 vaccination period.

RESULTS

The period of COVID-19 pandemic brought an increase in vaccine coverage globally. Elbow's method determined that the optimal number of clusters in vaccination uptake is 2. Apulia, Basilicata, Emilia Romagna, Liguria, Molise, Tuscany, and Umbria in 2019 belong less to the group with low flu vaccination uptake (G1) but increase their tendency to belong to this group over time: they decrease their propensity to be vaccinated for flu. For others, it seems that COVID-19 served as a push to increase flu vaccination coverage rates. Sicily appears to be the region that has responded best to the pandemic, changing its membership value from 2019 to 2022.

CONCLUSION

The present study highlights that the COVID-19 era has resulted in a higher flu vaccination coverage rate. Moreover, the regional level's improvement or worsening in flu vaccination coverage rate is not affected by the historical gap and socio-cultural and economic differences prevailing among Italian regions.

Identifying Barriers to Basic Needs, Academic Success, and the Vaccination Pattern among College Students during the COVID-19 Pandemic

College students face significant challenges during large-scale disease outbreaks that potentially compromise their basic needs, vaccine confidence, and academic success. Using a cross-sectional design and convenience sampling, we examined the impact of COVID-19 among college students (N = 828). The survey was administered using the Qualtrics survey platform to collect data on multiple demographic and health behaviors of students in the summer semester (2021). Our study demonstrated that the most common financial shock experienced by the study participants was job loss, with less remarkable changes in food and housing insecurities. Academically, students had the most difficulty learning online compared to other modalities (face-to-face, Hyflex, etc.) and struggled with staying motivated. They also struggled with group work and finding appropriate learning spaces. However, many did not use university support systems such as career and tutoring services. Exploring the COVID-19 vaccination attitudes, we found that only age, ethnicity, classification, and health insurance status were associated with getting vaccinated (p < 0.05). When the learning environment was assessed for various modalities, only college attendance was significantly associated (p < 0.05) with the accessible platforms (online, Hyflex, face-to-face, and others); however, nearly 40% of students reported difficulty learning on an online learning platform compared other categories that had much lower proportions. Our findings underscore an immediate need for universities to take measures to improve their preparedness and response strategies to mitigate the negative effects of future large-scale public health emergencies among students.

Vaccine hesitancy for COVID19: what is the role of statistical literacy?

Introduction

Vaccination is an important measure used to control the spread of COVID19. The estimation of risk versus benefit of vaccination is based on the understanding of information about the vaccine. Statistics are frequently part of communications about COVID19. Individuals that do not have an adequate foundation of statistical knowledge may not be able to properly assess associated risks and benefits. This study aims to assess the association between statistical literacy and hesitation to receive the COVID19 vaccine.

Methods

A nationally representative sample of 2,138 adults, recruited through CINT United States, Inc., (Lawrenceville, NJ; http://www.cint.com), completed an internet survey in the summer of 2021. This survey collected demographic measures and information about COVID19 vaccination status. The competency of respondents on various basic statistical concepts was assessed along with the corresponding confidence of respondents in their answers. A multivariable logistic regression model was constructed to assess the relationship between vaccine hesitancy and statistical literacy while controlling for covariates of interest.

Results

Statistical literacy was found to have a negligible association with COVID19 vaccine hesitancy (OR 1.01; 95% CI 1.00-1.02). In addition, differences in the proportion receiving the COVID19 vaccine between political affiliations, income levels, race groups, and ethnicities were observed.

Discussion

The statistical knowledge of the general American public is not commensurate with the need to be literate in basic statistical concepts in the data-driven world in which we live. An effective way to stem vaccine hesitancy may rely on increased statistical knowledge to not be biased by preconceived beliefs shaped by misinformation.

Vaccine Hesitancy in College Students

(1) Background: Following the COVID-19 pandemic, vaccine hesitancy has become an increasingly important topic and has created significant concerns in public health. It is important to explore vaccine hesitancy among college students as they have been identified to be a high-risk group for COVID-19 transmission. This study aims to investigate COVID-19 vaccine hesitancy in college students on a midsized midwestern university campus. (2) Methods: Data were collected from 311 undergraduate and graduate college students during June and July 2021. Participants completed a survey on COVID-19 vaccine behaviors, perceptions, and opinions. Quantitative and qualitative analysis was performed to identify vaccine hesitancy and influencing factors in the student population. (3) Results: The results of this study demonstrated significant relationships between older and younger undergraduate students (OR > 1, p < 0.05), students who received a yearly influenza vaccine and those that did not (p < 0.05), and students who had a previous COVID-19 infection and those that did not (OR > 1, p < 0.05). We also determined a significant difference between some racial/ethnic groups and vaccine hesitancy status. (4) Conclusions: COVID-19 vaccine hesitancy exists on college campuses, and is influenced by age and student status, influenza vaccination status, previous COVID-19 infection, and race/ethnicity.

"If You are Going to Step on This Campus, You Have to Get Vaccinated": A Qualitative Understanding of COVID-19 Vaccine Hesitancy Among Black Emerging Adults Returning to College Campuses

For the academic year 2021-2022, many American colleges mandated the COVID-19 vaccine for students to return to campus. However, when academic leaders put these mandates into effect, they may have failed to consider the emotional impact on vaccine hesitant students, especially students who have been historically marginalized or underrepresented such as Black emerging adults. This qualitative study explored how vaccine hesitant Black emerging adults describe and understand their return to academia and, how the historical mistreatment of Black Americans influenced their feelings and decision-making process around the vaccine mandates. The researcher conducted semi-structured interviews with 14 respondents, ages 18-25. The following themes were identified using thematic analysis: "…The Black Experience": Historical Racism and Medical Misrepresentation; Personal and External Reasons for Vaccine Hesitancy; Factors Impacting the Final Decision to get Vaccinated; Experiencing Varied Emotions about being Vaccinated. Findings demonstrate that the historical mistreatment of Black individuals shaped respondents' experience and informed their hesitancy about being vaccinated. Further, while all respondents ultimately complied with the vaccine mandate and were able to return to campus, overall feelings post vaccination varied. Implications for future research, higher education, and clinical practice are discussed.

Factors Affecting Influenza Vaccination Uptake and Attitudes among Lebanese University Students: The Impact of Vaccination Promotional Programs and COVID-19 Pandemic

Vaccination is the most effective preventative strategy against influenza, yet university students' influenza vaccination uptake remains low. This study aimed firstly to determine the percentage of university students who were vaccinated for the 2015-2016 influenza season and to identify reasons for non-vaccination, and secondly to examine the impact of external factors (on-campus/online influenza awareness campaigns and COVID-19 pandemic) on their influenza vaccination uptake and attitudes for the 2017-2018 and 2021-2022 influenza seasons. A descriptive study was conducted over three phases for three influenza seasons at a Lebanese university in the Bekaa Region. Based on data collected in 2015-2016, promotional activities were developed and implemented for the other influenza seasons. This study was conducted using an anonymous, self-administered questionnaire by students. The majority of the respondents in the three studies did not receive the influenza vaccine (89.2% in the 2015-2016 study, 87.3% in the 2017-2018 study, and 84.7% in the 2021-2022 study). Among the unvaccinated respondents, the main reason for non-vaccination was that they thought that they did not need it. The primary reason for vaccination among those who were vaccinated was that they believed they were at risk of catching influenza in a 2017-2018 study and due to the COVID-19 pandemic in the 2021-2022 study. As for attitudes towards influenza vaccination post-COVID-19, significant differences were shown among the vaccinated and unvaccinated respondents. The vaccination rates among university students remained low despite of the awareness campaigns and COVID-19 pandemic.

COVID-19 Pandemic Control Measures and Their Impact on University Students and Family Members in a Central Region of Spain

The first waves of the COVID-19 pandemic were times of great change in the lives of university students and their families in Spain. The aim of this study was to explore the psychosocial aspects and preventive measures carried out during the COVID-19 pandemic by students and family members of the nursing degree students of the University of Valladolid (Spain). The number of people surveyed was 877, by means of an ad hoc questionnaire. Relationships between variables were established by means of the Chi-square test and Student's t-test. In addition, multivariate logistic regression was generated. The significance level used was 0.05. Students and family members maintained preventive measures= such as hand washing, correct use of masks =in closed places, avoiding crowds and maintaining social distance, but at low rates (close to 20% in all cases). Regarding psychosocial aspects, 41.07% of the participants suffered from anxiety and loneliness, while 5.2% needed to take drugs to reduce anxiety or sleep and 66.07% were dependent on technology. Suicidal behavior is related to stress, anxiety, loneliness, poor family relationships, psychotropic drug use and technology abuse. The pandemic has caused life changes in university students and their families at the psychosocial level, generating high figures of suicidal ideation regardless of age. Preventive measures adopted to control the pandemic have not been followed for the most part.

Perspectives of Older Adults on COVID-19 and Influenza Vaccination in Ontario, Canada

INTRODUCTION/OBJECTIVES

Addressing vaccine hesitancy has become an increasingly important public health priority in recent years. There is a paucity of studies that have focused on vaccine hesitancy among older adults, who are known to be at greater risk of complications from infections such as COVID-19. We aim to explore the attitudes and beliefs of older adults regarding COVID-19 and influenza vaccines in Toronto, Ontario.

METHODS

Older adults enrolled in the Student Senior Isolation Prevention Partnership (SSIPP) program at the University of Toronto were contacted to participate in a phone survey and semi-structured interview. Survey data was analyzed descriptively, and attitude toward vaccination was compared between sociodemographic groups by using Fisher's exact test. Interview audio files were transcribed verbatim and analyzed inductively for themes and sub-themes.

RESULTS

All thirty-three (100%) older adults reported that they had received the first and second doses of the COVID-19 vaccine. Twenty-six (78.8%) participants reported intent to get vaccinated against influenza or had already received the influenza vaccine that year. Notably, only 2 out 7 (28.6%) individuals who did not plan to get vaccinated against influenza believed that vaccines offered by health providers are beneficial and only 3 out of 7 (42.9%) agreed that getting vaccines is a good way to protect oneself from disease. No other significant differences in attitudes among participants were found when compared by gender, ethnicity, or education level. The qualitative data analysis of interview transcripts identified 5 themes that impact vaccine decision making: safety, trust, mistrust, healthcare experience, and information dissemination and education.

CONCLUSIONS

Our data showed that older adults in the SSIPP program generally had positive views toward vaccination, especially toward the COVID-19 vaccines. However, several concerns regarding the effectiveness of the vaccines were brought up in interviews, such as the speed at which the vaccines were produced and the inconsistency in government messaging.

The Influence of the Health Belief Model on the Decision to Get the COVID-19 Vaccine: An International Survey Study of College Students

To better prepare for a potential future pandemic, it is important to investigate factors that influenced responses to the recent COVID-19 pandemic. The aim of the present study was to investigate factors that influenced the decision to get the COVID-19 vaccine. The COVID-19 pandemic has affected almost everyone throughout the world. Vaccines are a significant factor in managing a pandemic. As vaccines are developed, governments develop vaccine roll-out plans. Unfortunately, vaccine hesitancies can slow the implementation of any vaccine program. A question arises as to the factors that are associated with the decision to get vaccinated. The present study explored associations between vaccine hesitancy, and the Health Belief Model (HBM) in student samples from the Czech Republic, Israel, and the United States. From August, 2021 through December, 2021, an online survey was distributed in Czech, Hebrew, and English. A total of 447 participants completed the survey. A binomial logistic regression was conducted to ascertain the influence of perceived susceptibility, severity, benefits, and barriers on the likelihood that participants are vaccinated. Results revealed that the factors of perceived severity and perceived benefits explained 52.6% (Nagelkerke R2) of the variance in vaccination. An analysis of Variance (ANOVA) found significant differences between countries for the 4 HBM factors. Based on these findings, it is recommended that policymakers put forth added emphasis on the severity of a virus and the benefits associated with the vaccine. Further, since there appears to be variability between countries in perceptions of the virus, and associated vaccine, governments should consider factors within their own environment when developing a strategy to combat a pandemic. More specifically, government could explore their own strengths, weaknesses, opportunities, and threats as they develop a pandemic strategy. Additional practical and theoretical implications are discussed.

A qualitative study exploring healthcare providers’ and trainees’ barriers to COVID-19 and influenza vaccine uptake

Background

Vaccines are effective biological interventions which reduce health burdens and protect healthcare providers from vaccine-preventable diseases. However, there are concerns about varying levels of vaccination coverage of influenza and COVID-19 vaccines among those working in healthcare. The aim of this study was to identify barriers and facilitators to COVID-19 and influenza vaccinations among healthcare providers and trainees using the Theoretical Domains Framework (TDF).

Methods

Semi-structured interviews (n = 18) were carried out with healthcare providers and trainees in Canada. A thematic analysis approach was used to code interview transcripts and match findings to TDF domains and broader categories.

Results

Three overarching themes were generated from six TDF domains and three inductively generated categories: (1) making informed health decisions with an added responsibility to protect oneself and patients; (2) a pro-vaccine social network, widespread accessibility, and pursuing a sense of normalcy; and (3) seeking a more nuanced, respectful, and calculated approach to vaccine communication and policy implementation.

Conclusion

These findings help to identify factors associated with influenza and COVID-19 vaccine uptake among individuals in the healthcare field. Addressing these factors may improve healthcare provider sentiments surrounding vaccines, lead to better patient education, and increased uptake of vaccinations with the potential for seasonal booster doses.

The choice of Taiwanese college students to vaccinate against severe special infectious pneumonia COVID-19 based on the integrated theory of planning behavior

Taiwan's coronavirus (COVID-19) vaccine procurement was delayed until October 2021. With the vaccine's introduction in Taiwan, the public will have an opportunity to choose vaccination. Choosing to vaccinate involves considerations regarding the trade-off between the protective power of the vaccine and its side effects, which is a planned behavior. College students have considered high-risk objects for COVID-19 outbreaks given their lifestyle, and their efficient vaccination may help reduce mutual infection between college students and the general public. This study obtained 707 valid questionnaires from Taiwan college students (20 years old and above). We investigated several factors during our college students' survey regarding vaccination. Among this integrated TPB model, "Attitude," "Subjective Norm," "Perceived Behavioral Control," and "COVID-19 Information Asymmetry" had a positive impact on vaccination "Behavioral Intention." COVID-19 information asymmetry positively and significantly affected behavioral intention through perceived behavioral control, while perceived behavioral control had a mediating effect. To promote the behavioral intention of college students to choose COVID-19 vaccination, public and private departments for epidemic prevention must aim to overcome the self-efficacy barriers of perceived behavioral control and promote the primary group influence effect of subjective norm and the self-interest factor of attitude. Governments and NGOs should also ensure prompt and accurate transmission of epidemic and vaccine information and actively investigate and prohibit misleading details from unknown sources and no scientific basis. Such a policy will generate trust, effectively increasing the vaccination rate and reducing cluster infection.

COVID-19 and Influenza Coinfection Outcomes among Hospitalized Patients in the United States: A Propensity Matched Analysis of National Inpatient Sample

This study aims to provide comparative data on clinical features and in-hospital outcomes among U.S. adults admitted to the hospital with COVID-19 and influenza infection using a nationwide inpatient sample (N.I.S.) data 2020. Data were collected on patient characteristics and in-hospital outcomes, including patient's age, race, sex, insurance status, median income, length of stay, mortality, hospitalization cost, comorbidities, mechanical ventilation, and vasopressor support. Additional analysis was performed using propensity matching. In propensity-matched cohort analysis, influenza-positive (and COVID-positive) patients had higher mean hospitalization cost (USD 129,742 vs. USD 68,878, p = 0.04) and total length of stay (9.9 days vs. 8.2 days, p = 0.01), higher odds of needing mechanical ventilation (OR 2.01, 95% CI 1.19-3.39), and higher in-hospital mortality (OR 2.09, 95% CI 1.03-4.24) relative to the COVID-positive and influenza-negative cohort. In conclusion, COVID-positive and influenza-negative patients had lower hospital charges, shorter hospital stays, and overall lower mortality, thereby supporting the use of the influenza vaccine in COVID-positive patients.

Attitudes of COVID-19 vaccination among college students: A systematic review and meta-analysis of willingness, associated determinants, and reasons for hesitancy

The significance of COVID-19 vaccine has been declared and this study synthesizes the attitudes and determinants in vaccination hesitancy of college students. We searched in PubMed, Web of Science, Cochrane Library and CNKI to enroll the related studies. The modified NOS was used for quality evaluation. Proportion and OR with 95% CI were pooled to estimate the acceptance rates and determinants of COVID-19 vaccination. Data of 34 studies involving 42 countries were pooled. The pooled acceptance rate of COVID-19 vaccination among all the college students was 69% and varies between countries, while medical students have a slightly higher acceptancy rate. Knowledge, trust conception, social behavior, and information sources were important for their decision. Most of the college students intended to COVID-19 vaccination, but the proportion varied among countries. Governments should strengthen credibility, convey trusted information with media influences and improve vaccination services in urging students to be vaccinated.

Health information and COVID-19 vaccination: Beliefs and attitudes among Japanese university students

Coronavirus disease 2019 (COVID-19) vaccination of adolescent and young adults is important for infection control. Factors influencing vaccination behavior in this age group include the source of information about the vaccine and social norms. However, there are few studies on factors influencing vaccination behavior among Japanese university students. This study aimed to assess beliefs, attitudes, and sources of information about the COVID-19 vaccine among university students in Japan. A cross-sectional online questionnaire survey was conducted among students in Teikyo University, Japan in September, 2021. The survey was designed to collect demographic information, vaccination status, attitudes, beliefs, and anxiety about the vaccine, sources of information, and whether or not the participant watched an educational movie. The factors associated with beliefs and attitudes were analyzed using logistic and linear regression. A total of 4,062 valid questionnaires were retrieved. The positive vaccine behavior group included 3,725 students (91.7%). The most common source of information on the COVID-19 vaccine was TV/radio (75.0%), and the most common Social networking service (SNS) for COVID-19 information was Twitter (31.1%). Approximately 85% students believed in the efficacy of vaccination. Positive attitude was associated with female sex and watching an educational movie by the university. Concern about the vaccine was positively associated with information from acquaintances or Instagram, and negatively associated with information from Twitter, and watching the educational movie. The majority of students had positive beliefs and attitudes toward COVID-19 vaccination, and social media and educational movies produced by the university had a large influence on their attitude toward vaccination behavior. On the contrary, some students were anxious about vaccination. Promotion of educational movies on social media by the universities is an effective way to encourage vaccination among young people.

Examining the relationships between trust in providers and information, mistrust, and COVID-19 vaccine concerns, necessity, and intentions

To facilitate maximum uptake of the COVID-19 vaccine, the roles of medical trust and mistrust of healthcare professionals must be examined. Previous work suggests that trust and mistrust may have differential impacts on vaccination intention via vaccine necessity and concerns. Multigroup structural equation modeling was utilized to test whether vaccine necessity and concerns mediated the associations between trust in providers and health information, mistrust of providers, and willingness to get the COVID-19 vaccine. The model was found to be invariant across Black and White respondents. Trust in providers and trust in healthcare information exerted indirect effects on intentions through vaccine necessity, while mistrust of providers exerted indirect effects through vaccine concerns. Unlike previous work, the forms of trust did not influence vaccine concerns. The findings have implications for future communication efforts from healthcare professionals and health messengers.

Undergraduate Vaccine Hesitancy and the Influence of "Home" Locales

PURPOSE

In the US, the COVID-19 pandemic has exposed deeply rooted resistance to public health. This has important consequences for SARS-CoV-2 variant spread and for future uptake of influenza and other vaccines. We examine these phenomena in Missouri, where its low vaccination rates, high levels of uninsured residents, predominance of conservative values, and stark rural-urban divides are intricately connected to public health resistance. The Socio-Ecological model guides our approach.

METHODS

We use data from the Fall 2020 Midwestern University (MWU-a pseudonym) Study of Seropositivity and Risk for SARS-CoV-2 and COVID-19 which are harmonized with the American Community Survey, Missouri County-Level Study, and the USDA Rural-Urban Continuum Codes to estimate multi-level regression models on the relationship between undergraduate students' "home" locales and their own COVID-19 and influenza vaccine hesitancy.

FINDINGS

The availability of primary care physicians, the prevalence of influenza vaccinations, and location type at the county level, as well as the percentage of residents without health insurance at the zip code level differentially predict COVID-19 and influenza vaccine hesitancy.

CONCLUSIONS

There is a link between county-level health and geographic characteristics, and individuals'-who were influenced by those counties because that is where their parents live-hesitancy towards vaccines. Identifying feasible, precise, local solutions to reducing vaccine hesitancy could take place if community members and other stakeholders would be open to changes in local-level health policy or practice.

Strengthened belief in vaccine effectiveness predicted increased COVID-19 vaccination intention and behaviour: Results from a nationally representative longitudinal survey of U.S. adults from July 2020 to April/May 2021

Vaccine hesitancy remains a major barrier to ending the COVID-19 pandemic in the United States (U.S.) and an important target for communication interventions. Using longitudinal survey data, we examined whether baseline levels and changes in beliefs about the COVID-19 vaccines predicted change in vaccination intention/behaviour. Repeated measures were collected from a nationally representative sample of U.S. adults (n = 665) in July 2020 and April/June 2021. Linear regressions associated change in COVID-19 vaccination intention/behaviour with changes in beliefs about the COVID-19 vaccines' safety, effectiveness in protecting others from infection, and effectiveness in protecting oneself from infection. Changes in beliefs from T1 to T2 were significantly associated with change in vaccination outcomes for all belief types (safety B = 0.39, SE = 0.07; effectiveness for self B = 0.38, SE = 0.09; effectiveness for others B = 0.43, SE = 0.07). Cross-lagged models suggested a reciprocal causal relationship between pro-vaccine beliefs and vaccination intention/behaviour: Intention to get vaccinated at T1 predicted strengthened safety and effectiveness beliefs at T2. T1 effectiveness beliefs predicted T2 vaccination intention/behaviour, though T1 safety beliefs did not. Communication interventions highlighting the protective benefits of COVID-19 vaccines may be particularly successful in reducing vaccine hesitancy.

Evaluation of knowledge and barriers of influenza vaccine uptake among university students in Saudi Arabia; a cross-sectional analysis

Background

Influenza vaccine hesitancy is a significant threat to global maneuvers for reducing the burden of seasonal and pandemic influenza. This study estimated the vaccine uptake, barriers, and willingness for influenza vaccines among university students in Saudi Arabia.

Methods

A cross-sectional survey was conducted among health science (HS) and non-health science (NHS) university students. A 31-item questionnaire was used to ascertain the vaccination rate, barriers, and willingness for the flu vaccine.

Results

This study included 790 students (mean age: 21.40 ± 1.94 years), 246 (31.1%) from HS and 544 (68.9%) from NHS disciplines. About 70% did not take flu shots before the arrival of the winter. The mean knowledge score was 7.81 ± 1.96, where 20.4%, 67.6%, and 12% of respondents had good, moderate, and poor knowledge regarding flu vaccines. The relative importance index (RII) analysis showed a lack of recommendation from physicians (51.5%, RI ranked: 1) was a top-ranked barrier to vaccine uptake, followed by negative perceptions and accessibility issues. Only 36.6% of the participants were willing to get vaccinated every year, 70% were willing to receive a vaccine on their doctor's recommendations, and 46% agreed to vaccinate if vaccines were freely available in the university. The knowledge, barriers, and willingness widely varied across students from two disciplines.

Conclusions

Our analysis underscored low flu vaccine uptake among university students. In addition, the study participants' knowledge was unsatisfactory, and they were less inclined to receive the flu vaccine in the future. Lack of recommendation from the physicians, negative perceptions towards the flu vaccine, and difficult accessibility were found as significant barriers to the vaccine uptake. A multidimensional approach at educational institutes to cover the knowledge gap and address the barriers curtailing the vaccination rate among students is recommended.

Public sentiments toward COVID-19 vaccines in South African cities: An analysis of Twitter posts

Amidst the COVID-19 vaccination, Twitter is one of the most popular platforms for discussions about the COVID-19 vaccination. These types of discussions most times lead to a compromise of public confidence toward the vaccine. The text-based data generated by these discussions are used by researchers to extract topics and perform sentiment analysis at the provincial, country, or continent level without considering the local communities. The aim of this study is to use clustered geo-tagged Twitter posts to inform city-level variations in sentiments toward COVID-19 vaccine-related topics in the three largest South African cities (Cape Town, Durban, and Johannesburg). VADER, an NLP pre-trained model was used to label the Twitter posts according to their sentiments with their associated intensity scores. The outputs were validated using NB (0.68), LR (0.75), SVMs (0.70), DT (0.62), and KNN (0.56) machine learning classification algorithms. The number of new COVID-19 cases significantly positively correlated with the number of Tweets in South Africa (Corr = 0.462, P < 0.001). Out of the 10 topics identified from the tweets using the LDA model, two were about the COVID-19 vaccines: uptake and supply, respectively. The intensity of the sentiment score for the two topics was associated with the total number of vaccines administered in South Africa (P < 0.001). Discussions regarding the two topics showed higher intensity scores for the neutral sentiment class (P = 0.015) than for other sentiment classes. Additionally, the intensity of the discussions on the two topics was associated with the total number of vaccines administered, new cases, deaths, and recoveries across the three cities (P < 0.001). The sentiment score for the most discussed topic, vaccine uptake, differed across the three cities, with (P = 0.003), (P = 0.002), and (P < 0.001) for positive, negative, and neutral sentiments classes, respectively. The outcome of this research showed that clustered geo-tagged Twitter posts can be used to better analyse the dynamics in sentiments toward community-based infectious diseases-related discussions, such as COVID-19, Malaria, or Monkeypox. This can provide additional city-level information to health policy in planning and decision-making regarding vaccine hesitancy for future outbreaks.

Prevalence of COVID-19 vaccine hesitancy in students: A global systematic review

Background: Examining the prevalence of coronavirus disease (COVID-19) vaccine hesitancy and understanding what motivates students to accept or reject a newly promoted vaccine has the potential in preventing rapid spread of infection and optimizing country-wide mass vaccination programs. This systematic review aimed to examine global COVID-19 vaccine hesitancy among students, and to identify an up-to-date and concise assessment of most common factors influencing vaccine acceptance and hesitancy around the world. Methods: A systematic search of peer-reviewed literatures indexed in reputable databases was performed. After obtaining the results via screening using PRISMA flow diagram, a total of 35 articles met the inclusion criteria and formed the basic structure of the study objectives. Results: The results revealed that, the worldwide pooled COVID-19 vaccine hesitancy rate was (x̅%)=29.8% (95% CI 23.37-36.23) among students. According to the country count assessment, the pooled vaccine hesitancy has been found to be ups and downs across the countries around the world such as  (x̅%)=32% (95% CI 20.04-43.97) in Asia, (x̅%)=(28.11%, 95% CI 18.83-37.40) in the United States, (x̅%)=15.59% (95% CI 8.23-22.95) in Europe, (x̅%)=55.93% (95% CI 40.31-71.55) in Africa, (x̅%)=20.4% in North America, and (x̅%)=22.5% in multi-ethnic areas in the reported student's COVID-19 vaccine hesitancy. In total, 10 key factors were identified. "Side effect" 45.41% (95% CI 29.68-61.14), "safety" 42.27% (95% CI 27.50-57.04), and "trust" 44.95%, (95% CI 26.51-63.39) were the overarching concerns in making student's vaccination decisions. Conclusions: The prevalence of COVID-19 vaccine hesitancy varied among the students; however, vaccine acceptance or refusal relies on several socio-psychological, societal, and vaccine related factors. This study helps the vaccine policy-makers and health stakeholders gain a better understanding of COVID-19 vaccination drive and design the vaccine promotion strategies. Health educational interventions could be the most preferred approach to improve student's adherence and knowledge about the COVID-19 vaccination consequences.

Cross-Sectional Study of University Students’ Attitudes to ‘On Campus’ Delivery of COVID-19, MenACWY and MMR Vaccines and Future-Proofing Vaccine Roll-Out Strategies

University students are a critical group for vaccination programmes against COVID-19, meningococcal disease (MenACWY) and measles, mumps and rubella (MMR). We aimed to evaluate risk factors for vaccine hesitancy and views about on-campus vaccine delivery among university students. Data were obtained through a cross-sectional anonymous online questionnaire study of undergraduate students in June 2021 and analysed by univariate and multivariate tests to detect associations. Complete data were obtained from 827 participants (7.6% response-rate). Self-reporting of COVID-19 vaccine status indicated uptake by two-thirds (64%; 527/827), willing for 23% (194/827), refusal by 5% (40/827) and uncertain results for 8% (66/827). Hesitancy for COVID-19 vaccines was 5% (40/761). COVID-19 vaccine hesitancy was associated with Black ethnicity (aOR, 7.01, 95% CI, 1.8–27.3) and concerns about vaccine side-effects (aOR, 1.72; 95% CI, 1.23–2.39). Uncertainty about vaccine status was frequently observed for MMR (11%) and MenACWY (26%) vaccines. Campus-associated COVID-19 vaccine campaigns were favoured by UK-based students (definitely, 45%; somewhat, 16%) and UK-based international students (definitely, 62%; somewhat, 12%). Limitations of this study were use of use of a cross-sectional approach, self-selection of the response cohort, slight biases in the demographics and a strict definition of vaccine hesitancy. Vaccine hesitancy and uncertainty about vaccine status are concerns for effective vaccine programmes. Extending capabilities of digital platforms for accessing vaccine information and sector-wide implementation of on-campus vaccine delivery are strategies for improving vaccine uptake among students. Future studies of vaccine hesitancy among students should aim to extend our observations to student populations in a wider range of university settings and with broader definitions of vaccine hesitancy.

COVID-19 Vaccine Hesitancy in a Rural Primary Care Setting

As the United States clamors with anti-vax protests, researchers seek to understand what social and behavioral values are keeping patients from electing to vaccinate themselves against the coronavirus disease 2019 (COVID-19) virus. Over the past year, the race to vaccinate has become less about developing working vaccines and more about finding ways to encourage vaccine uptake. This paper examines the question of vaccine hesitancy in rural Chemung County, NY. In identifying various psychosocial barriers to patient vaccination, which we hypothesize will be mostly political, we seek to understand the local mindset in the hope that our data guide the way to change it.

Awareness, Barriers and Concerns of Adolescents Toward the COVID-19 Vaccine: A Cross-Sectional Study in Singapore

Background

COVID-19 vaccination is a key public health measure to mitigate the crippling effects of the pandemic. COVID-19 vaccination began in adults and targeted adolescents at a later stage. However, medical decision-making on its uptake among the latter was unknown, which could be affected by their literacy and concerns about the vaccine. The study aimed to elucidate the awareness, concerns and barriers of adolescents toward the COVID-19 vaccine.

Methods

A cross-sectional online survey using a self-developed questionnaire was conducted between June to November 2021. The adolescent participants were students from institutes of post-secondary education who were recruited via convenience sampling. The data were collated from an officially approved electronic platform, audited and analyzed. Continuous and categorical variables were expressed as mean (standard deviation) and percentages, respectively.

Results

A total of 460 adolescents participated in the study (mean age: 16.99 ± 0.99; 73% female). Most of them (91.5%) were aware of the COVID-19 vaccines. The main barriers to vaccination were uncertainty about long-term health risks (38.6%) and vaccine efficacy (37.3%). Regarding the potential vaccine side effects, they were concerned about: anaphylactic shock (73.2%), low blood pressure (58.3%) and fast heartbeat (58.0%). Only 58% expressed willingness for repeated COVID-19 vaccination.

Conclusion

Despite high COVID-19 vaccine awareness, the adolescents were concerned about the potentially severe but rare side-effects. The study identified apprehension regarding vaccine efficacy and the potential long-term health impact as the main barriers to vaccination. Future studies should address these concerns to scale vaccination programs among adolescents.

Has the COVID-19 pandemic affected general vaccination hesitancy? Findings from a national study

Extensive media coverage and potential controversy about COVID-19 vaccination during the pandemic may have affected people’s general attitudes towards vaccination. We sought to describe key psychological antecedents related to vaccination and assess how these vary temporally in relationship to the pandemic and availability of COVID-19 vaccination. As part of an ongoing online study, we recruited a national (U.S.) sample of young gay, bisexual and other men who have sex with men (N = 1,227) between October 2019 and June 2021, and assessed the “4Cs” (antecedents of vaccination; range = 1–5). Overall, men had high levels of confidence (trust in vaccines; M = 4.13), calculation (deliberation; M = 3.97) and collective responsibility (protecting others; M = 4.05) and low levels of complacency (not perceiving disease risk; M = 1.72). In multivariable analyses, confidence and collective responsibility varied relative to the pandemic phase/vaccine availability, reflecting greater hesitancy during later stages of the pandemic. Antecedents also varied by demographic characteristics. Findings suggest negative effects of the COVID-19 pandemic on key antecedents of general vaccination and identify potential targets for interventions.

Potential of Microneedle Systems for COVID-19 Vaccination: Current Trends and Challenges

To prevent the coronavirus disease 2019 (COVID-19) pandemic and aid restoration to prepandemic normality, global mass vaccination is urgently needed. Inducing herd immunity through mass vaccination has proven to be a highly effective strategy for preventing the spread of many infectious diseases, which protects the most vulnerable population groups that are unable to develop immunity, such as people with immunodeficiencies or weakened immune systems due to underlying medical or debilitating conditions. In achieving global outreach, the maintenance of the vaccine potency, transportation, and needle waste generation become major issues. Moreover, needle phobia and vaccine hesitancy act as hurdles to successful mass vaccination. The use of dissolvable microneedles for COVID-19 vaccination could act as a major paradigm shift in attaining the desired goal to vaccinate billions in the shortest time possible. In addressing these points, we discuss the potential of the use of dissolvable microneedles for COVID-19 vaccination based on the current literature.

Chinese University Students' Awareness and Acceptance of the COVID-19 Vaccine: A Cross-Sectional Study

Purpose

The emergence of the mutant virus has exacerbated the COVID-19 epidemic, and vaccines remain an effective and viable means of resistance. As a socially influential young group, university students’ awareness and acceptance of the COVID-19 vaccine are crucial to achieving herd immunity. This study aimed to assess the awareness and acceptance of the COVID-19 vaccine among Chinese university students and identify possible factors associated with their awareness level and vaccine hesitancy.

Patients and Methods

An anonymous cross-sectional survey was conducted among Chinese university students between 10 and 28 June 2021. We collected information on the demographic characteristics, awareness and acceptance of the COVID-19 vaccine, and influencing factors. Sleep disturbances and anxiety disorders were also evaluated. Multinomial logistic regression analyses were performed.

Results

Among the 721 participants (aged 18 to 23 years) with a female predominance (68.9%), 40.4% of cases exhibited moderate awareness the COVID-19 vaccine, and 87.4% of cases expressed high acceptance of the vaccine. Participants’ awareness of the COVID-19 vaccine was associated with gender, ethnicity, region of residence, grade level, satisfaction with current state of pandemic control, the perceived likelihood of a COVID-19 pandemic rebound, the source number of COVID-19 information, concerns about differences in vaccine manufacturers, acceptance of current state-approved vaccines and insomnia level. Furthermore, age, preferred channels for vaccination and the acceptance of current state-approved vaccines were significantly associated with their acceptance of the vaccine.

Conclusion

This study reflected Chinese university students’ high acceptance, but insufficient awareness of the COVID-19 vaccine, some students have insomnia and anxiety problems. These require the government to take measures such as individualized publicity and education, adding professional psychological counseling courses to improve the university students’ awareness of vaccines and public health events, and comprehensively promote vaccination to cope with the ever-changing situation of the COVID-19 epidemic.

Cross-sectional study on COVID-19 vaccine hesitancy and determinants in healthcare students: interdisciplinary trainings on vaccination are needed

BACKGROUND

To ensure the success of COVID-19 vaccination, public authorities need to have the support of the entire population and build vaccine confidence. Identifying and understanding the determinants of vaccine acceptance is essential for conducting vaccine strategy. The aim was to estimate vaccine hesitancy among healthcare students in France and to investigate the associated factors.

METHODS

A web-based cross-sectional study was conducted in a large French University in greater Paris area, among 4927 healthcare students from the different training courses such as medicine studies, midwifery studies, physiotherapy studies, nurse studies and others health studies. The study was conducted between January 21 and February 8, 2021 based on a questionnaire including 25 single or multiple-choice questions, made using the free software Limesurvey. The link of the questionnaire was distributed to the students by the teachers and the student associations. The SAGE group definition of vaccine hesitancy was used. All estimates were weighted using the gender and training courses category of all healthcare students registered for the 2020-2021 year. Crude and adjusted weighted odds ratio (wOR) and 95% confidence interval (95%CI) were estimated using logistic regression.

RESULTS

A total of 1465 healthcare students answered. A proportion of 44.5% (95%CI = [41.7-47.3]) of them were considered as hesitant. Women were more hesitant (50.9, 95%CI = [48.0-53.9]) than men (21.6, 95%CI = [15.2-28.0]). Vaccine hesitancy was significantly associated with gender (wOR = 0.27, 95%CI = [0.18-0.39]) and training courses: medical students were less likely to be hesitant than students in the common and first year of several health studies (wOR = 0.48, 95%CI = [0.33-0.70]) while nursing students were more than 5 times more likely to be hesitant (wOR = 5.20, 95%CI = [3.71-7.28]). Students who did an internship during the epidemic (wOR = 0.53, 95%CI = [0.41-0.69]) and who downloaded the mobile contact-tracing mobile app "TousAntiCovid" (wOR = 0.34, 95%CI = [0.26-0.44]) were significantly less likely to be hesitant.

CONCLUSIONS

Overall vaccine hesitancy among healthcare students was high, substantial differences were found between training courses. To reduce these disparities, interdisciplinary lectures on vaccines for all healthcare students may be implemented and evaluated.

Effect of COVID-19 Pandemic on Influenza Vaccination Intention: A Meta-Analysis and Systematic Review

Poorer outcomes have been reported with COVID-19 and influenza coinfections. As the COVID-19 pandemic rages on, protection against influenza by vaccination is becoming increasingly important. This study examines how COVID-19 has influenced influenza vaccination intentions from a global perspective. A literature search was conducted on Embase, PubMed, and CNKI from 1 January 2019 to 31 December 2021 for articles reporting rates of influenza vaccination pre-COVID-19 (19/20 season), and intention and/or uptake of influenza vaccination post-COVID-19 (20/21 season). The changes in vaccination intention and reasons for changes were reported. Subgroup analyses were performed by region, gender, age, and occupation. Newcastle Ottawa Scale was used for quality assessment of the articles. Twenty-seven studies with 39,193 participants were included. Among 22 studies reporting intention to vaccinate in 20/21, there was increased intention to vaccinate (RR 1.50, 95% CI 1.32−1.69, p < 0.001) regardless of age, gender, and occupation. The remaining five studies reporting vaccination intention and uptake in 20/21 showed a similar increase (RR 1.68, 95%CI 1.20−2.36). Important determinants include historical vaccine acceptance, and perception of influenza severity and vaccine safety. The COVID-19 pandemic has increased intention to vaccinate against influenza internationally. The pandemic could be a window of opportunity to promote influenza vaccination and decrease vaccine hesitancy.

COVID-19 vaccine status and hesitancy in pharmacy students

INTRODUCTION

The purpose of this research is to determine pharmacy students' immunization status and attitudes towards receiving the COVID-19 vaccine. It will help determine if education is needed to increase the vaccination rate and, if so, what areas to target. The study will also provide insight into vaccine hesitancy among pharmacy students.

METHODS

In April 2021, a survey was sent to pharmacy students in professional years 1, 2, 3, and 4 at Western New England University in Springfield, Massachusetts. Information gathered included if the student had received and completed the vaccine series, why the student was motivated to receive the vaccine, or why they were hesitant, along with work and experiential rotation information.

RESULTS

The response rate to the survey was 63% (133 of 212). Eighty-six percent of the respondents were at least partially vaccinated against COVID-19. Four percent of respondents were not considering receiving the vaccine, 6% were, and another 4% were undecided. Unvaccinated students attributed their hesitancy mostly to being concerned about the vaccine's long-term effects (85%) followed by not wanting to miss an exam/class (23%). Vaccinated students were more likely to work at a site that administered the COVID-19 vaccine (81.6% vs. 50%, P = .003).

CONCLUSIONS

Despite the pandemic, COVID-19 vaccination rates were not higher than voluntary influenza vaccination rates. This study indicates that despite pharmacy students being witness to the risks associated with the pathogen, additional education is needed, and health care providers are not immune to misinformation and hesitancy.

Media Exposure and Media Credibility Influencing Public Intentions for Influenza Vaccination

Due to the low rate of influenza vaccination in China, this study explores the factors influencing the Chinese public’s influenza vaccination intentions. Based on the technology acceptance model (TAM), this study builds a theoretical model to examine the factors influencing Chinese public intentions toward influenza vaccination. We define media exposure and media credibility as external variables and the perceived characteristics of influenza vaccines as intermediate variables in the proposed model. A total of 597 valid questionnaires were collected online in this study. Combined with structural equation modeling (SEM), SPSS 22.0 and AMOS 17.0 were used to conduct empirical research, supporting the proposed research hypotheses. The results show that media exposure and media credibility have no direct effects on the audience’s intention to take the influenza vaccine. However, media exposure positively influences media credibility, influencing vaccination intentions through perceived usefulness (PU) and perceived ease of use (PEOU). Furthermore, PU and PEOU significantly positively influence behavioral intentions, and PEOU significantly affects PU. This paper has proven that media with better credibility gained more trust from the audience, indicating a new perspective for the promotion of influenza vaccination. This study suggests releasing influenza-related information via media with great credibility, further improving public acceptance of becoming vaccinated.

Potential factors influencing COVID-19 vaccine acceptance and hesitancy: A systematic review

BACKGROUND AND AIMS

Although vaccines are considered the most effective and fundamental therapeutic tools for consistently preventing the COVID-19 disease, worldwide vaccine hesitancy has become a widespread public health issue for successful immunization. The aim of this review was to identify an up-to-date and concise assessment of potential factors influencing COVID-19 vaccine acceptance and refusal intention, and to outline the key message in order to organize these factors according to country count.

METHODS

A systematic search of the peer-reviewed literature articles indexed in reputable databases, mainly Pub Med (MEDLINE), Elsevier, Science Direct, and Scopus, was performed between21stJune 2021 and10th July 2021. After obtaining the results via careful screening using a PRISMA flow diagram, 47 peer-reviewed articles met the inclusion criteria and formed the basic structure of the review.

RESULTS

In total, 11 potential factors were identified, of which the greatest number of articles (n = 28) reported "safety" (34.46%; 95% CI 25.05─43.87) as the overarching consideration, while "side effects" (38.73%; 95% CI 28.14─49.32) was reported by 22 articles, which was the next common factor. Other potential factors such as "effectiveness" were identified in 19 articles (29.98%; 95% CI 17.09─41.67), followed by "trust" (n = 15 studies; 27.91%; 95% CI 17.1─38.73),"information sufficiency"(n = 12; 34.46%; 95% CI 35.87─63.07),"efficacy"(n = 8; 28.73%; 95% CI 9.72─47.74), "conspiracy beliefs" (n = 8; 14.30%; 95% CI 7.97─20.63),"social influence" (n = 6; 42.11%; 95% CI 14.01─70.21), "political roles" (n = 4; 16.75%; 95% CI 5.34─28.16), "vaccine mandated" (n = 4; 51.20%; 95% CI 20.25─82.15), and "fear and anxiety" (n = 3; 8.73%; 95% CI 0.59─18.05). The findings for country-specific influential vaccination factors revealed that, "safety" was recognized mostly (n = 14) in Asian continents (32.45%; 95% CI 19.60─45.31), followed by the United States (n = 6; 33.33%; 95% CI12.68─53.98). "Side effects" was identified from studies in Asia and Europe (n = 6; 35.78%; 95% CI 16.79─54.77 and 16.93%; 95% CI 4.70─28.08, respectively), followed by Africa (n = 4; 74.60%, 95% CI 58.08─91.11); however, public response to "effectiveness" was found in the greatest (n = 7) number of studies in Asian countries (44.84%; 95% CI 25─64.68), followed by the United States (n = 6; 16.68%, 95% CI 8.47─24.89). In Europe, "trust" (n = 5) appeared as a critical predictor (24.94%; 95% CI 2.32─47.56). "Information sufficiency" was identified mostly (n = 4) in articles from the United States (51.53%; 95% CI = 14.12─88.74), followed by Asia (n = 3; 40%; 95% CI 27.01─52.99). More concerns was observed relating to "efficacy" and "conspiracy beliefs" in Asian countries (n = 3; 27.03%; 95% CI 10.35─43.71 and 18.55%; 95% CI 8.67─28.43, respectively). The impact of "social influence" on making a rapid vaccination decision was high in Europe (n = 3; 23.85%, 95% CI -18.48─66.18), followed by the United States (n = 2; 74.85%). Finally, "political roles" and "vaccine-mandated" were important concerns in the United States.

CONCLUSIONS

The prevailing factors responsible for COVID-19 vaccine acceptance and hesitancy varied globally; however, the global COVID-19 vaccine acceptance relies on several common factors related to psychological and, societal aspect, and the vaccine itself. People would connect with informative and effective messaging that clarifies the safety, side effects, and effectiveness of prospective COVID-19 vaccines, which would foster vaccine confidence and encourage people to be vaccinated willingly.

A Knowledge, Attitude, and Perception Study on Flu and COVID-19 Vaccination during the COVID-19 Pandemic: Multicentric Italian Survey Insights

In January 2020, Chinese health authorities identified a novel coronavirus strain never before isolated in humans. It quickly spread across the world, and was eventually declared a pandemic, leading to about 310 million confirmed cases and to 5,497,113 deaths (data as of 11 January 2022). Influenza viruses affect millions of people during cold seasons, with high impacts, in terms of mortality and morbidity. Patients with comorbidities are at a higher risk of acquiring severe problems due to COVID-19 and the flu—infections that could impact their underlying clinical conditions. In the present study, knowledge, attitudes, and opinions of the general population regarding COVID-19 and influenza immunization were evaluated. A multicenter, web-based, cross-sectional study was conducted between 10 February and 12 July 2020, during the first wave of SARS-CoV-2 infections among the general population in Italy. A sample of 4116 questionnaires was collected at the end of the study period. Overall, 17.5% of respondents stated that it was unlikely that they would accept a future COVID-19 vaccine (n = 720). Reasons behind vaccine refusal/indecision were mainly a lack of trust in the vaccine (41.1%), the fear of side effects (23.4%), or a lack of perception of susceptibility to the disease (17.1%). More than 50% (53.8%; n = 2214) of the sample participants were willing to receive flu vaccinations in the forthcoming vaccination campaign, but only 28.2% of cases had received it at least once in the previous five seasons. A higher knowledge score about SARS-CoV-2/COVID-19 and at least one flu vaccination during previous influenza seasons were significantly associated with the intention to be vaccinated against COVID-19 and influenza. The continuous study of factors, determining vaccination acceptance and hesitancy, is fundamental in the current context, in regard to improve vaccination confidence and adherence rates against vaccine preventable diseases.

Vaccine Acceptance and Hesitancy among College Students in Nevada: A State-Wide Cross-Sectional Study

The purpose of this study was to identify factors related to COVID-19 vaccine acceptance and hesitancy in a diverse state-wide population of students. An electronic survey was emailed to students in the Nevada System of Higher Education to assess effects of the pandemic. The survey included questions related to vaccine status, interest in receiving the COVID-19 vaccine, factors influencing these decisions, and sources of health information. Among the 3773 respondents, over half (54%) were accepting of the vaccine, including vaccinated students (18.9%). Nearly one quarter (23.5%) expressed hesitancy to receive the vaccine, citing concerns about side effects and the need for more research. Factors related to hesitancy included female gender, increasing age, place of residence, marital status, and Black or Native American race. Vaccine hesitant respondents were less likely than other respondents to rely on public health agencies or newspapers for health information, and more likely to rely on employers, clinics, or “no one”. Culturally appropriate efforts involving COVID-19 vaccine information and distribution should target certain groups, focusing on factors such as side effects, development and testing of the vaccine. Research should investigate sources of health information of people who are hesitant to receive vaccines.
