Attitudes towards COVID-19 vaccination, vaccine hesitancy and intention to take the vaccine

Perceived impact of discussions with a healthcare professional on patients' decision regarding COVID-19 vaccine

There is evidence that advice from Healthcare Professionals (HCPs) plays an important role in patients' decision to get vaccinated, but the extent to which patients perceive this impact is unclear. The aim of this study was to assess the perceived impact of a discussion with a HCP on participants' decision to be vaccinated against COVID-19. A cross-sectional survey was conducted among adults who consulted a general practitioner (GP) or a pharmacist in Ile-de-France, France, after COVID-19 vaccines became available (October-November 2021 period). A total of 344 participants were included, 65.2% of whom reported having had a discussion about COVID-19 vaccines with a HCP. Overall, 55% of participants were advised to be vaccinated by their HCP. Most of the discussions took place with a GP (n = 203, 48.9%). According to 52.5% of participants, the discussion had a positive impact, i.e. it was perceived as encouraging vaccination. The latter reported that, among HCPs, GPs had the greatest number of discussions with a positive impact on the decision to be vaccinated against COVID-19 (93.1%). In the study population, the COVID-19 vaccine hesitancy rate, according to the WHO definition, was high (38.1%), although the COVID-19 vaccine coverage rate was 87.1%. Vaccine hesitant participants were more likely to report a discussion that had a perceived negative impact on their decision to get vaccinated (20.0%) than non-hesitant participants (5.8%, p = .004).

Prevalence, under-reporting, and epidemiological surveillance of COVID-19 in the Araguaína City of Brazil

Asymptomatic and underreported individuals remain a source of coronafig disease 2019 (COVID-19) transmission to others. Data on the prevalence and epidemiological factors influencing transmission are fundamental for establishing control measures, especially in vulnerable regions such as the Amazon. This study aimed to determine the point prevalence and active infection of COVID-19 among the population in Araguaína, a Brazilian city located in the Amazon region, analyzed the socioeconomic and behavioral variables of a statistically representative sample of this population using an epidemiological survey, and identify the viral genomic diversity in the region. During the sixth epidemiological week of 2021 (February 8 to 12), samples of 497 inhabitants of the municipality asymptomatic for respiratory syndromes underwent reverse transcription-quantitative polymerase chain reaction and serological tests (immunoglobulin M and immunoglobulin G). A questionnaire collated data on socioeconomic factors, prevention measures, and health status history. The active infection rate was 6.2%, and the prevalence was 13.5% of the study population. Active infection cases were under-reported; each reported positive case represented 14-28 under-reported cases. Lineages P.2, P.1, and B.1.1 were detected. Working from home was a protective factor against the infection, and clinical signs of fever, dry cough, and loss of taste or smell were associated with testing positive (p <0.05). A descriptive analysis of the indicators revealed that the entire population was susceptible to the disease. Intensified vaccination strategies are required regardless of socioeconomic factors, health conditions, and preventive measures. Implementation of objective, comprehensive, and efficient management tools to minimize the spread of COVID-19 in this municipality can serve as a model for other regions of Brazil.

Attitude toward vaccination against COVID-19 and acceptance of the national "QazVac" vaccine in the Aktobe city population, West Kazakhstan: A cross-sectional survey

The scale of emergency caused by COVID-19, the ease of survey, and the crowdsourcing deployment guaranteed by the latest technology have allowed unprecedented access to data describing behavioral changes induced by the pandemic. The study aimed to present the survey results identifying attitudes toward vaccination against COVID-19 among the population of West Kazakhstan, the level of confidence in the national QazVac vaccine, and the role of different sources of information on COVID-19 in decision-making concerning vaccination. A computer-assisted survey was conducted using WhatsApp messenger. Overall, 2,009 participants responded, with a response rate of 92%. Most (83.1%) were immunized against COVID-19; among them, 20.1% obeyed the request of their employers that had been practiced within non-pharmaceutical interventions to contain the disease. The youngest respondents, individuals with a college education, students, and employed people, as well as those with chronic diseases, showed positive attitudes toward vaccination (all p<0.05). About two-thirds of respondents (69.2%) expressed trust in all types of vaccines against COVID-19. Of those who refused vaccination (16.9%), about one-third feared vaccination consequences, and more than a third (38.2%) reported anti-vaccine sentiments. The decisive factors in accepting vaccination were trust in official sources of information (reports of medical experts, etc.) and, mainly, subjectively interpreted sufficiency of information about the disease, which had increased the odds of being vaccinated by 63.9% (OR 1.71, 95% CI [1.3;2.26], p<0.05). Confidence in the domestic QazVac vaccine was expressed by 37.7% of respondents. History and severity of COVID-19 disease did not play a role in positive perceptions of vaccination, while illness after vaccination substantially affected vaccination approval (p 0.021). No significant differences have been observed regarding the overall performance across five vaccines (QazVac, Sputnik V, CoronaVac, Hayat-Vax, and BioNTech/Pfizer) available for Kazakhstan's population (p 0.27).

Determinants of COVID-19 vaccination intention in Central and Eastern Europe: A cross-sectional study in Poland, Romania, and Slovenia

BACKGROUND

Identifying predictors of vaccination intention is critical to developing appropriate programs and campaigns targeting groups reluctant to be vaccinated. This study aimed to identify the determinants of vaccination intention at the beginning of the COVID-19 pandemic in three Central and Eastern European (CEE) countries: Poland, Romania, and Slovenia.

METHODS

In this cross-sectional study, a sample of unvaccinated 1723 Poles, Romanians, and Slovenians completed an online survey (April 2021). Questions included measures of vaccination intention, attitudes towards vaccines, conspiracy mindset, preference for a type of vaccine, and trust in information sources.

RESULTS

The results showed that mistrust of vaccine benefits and concerns about commercial profiteering negatively predicted vaccination intention. Conversely, trust in information from medical professionals and scientists, official sources, and traditional media was positively related to vaccination intention, while trust in digital media was negatively related to vaccination intention. In addition, preference for mRNA vaccine type was a positive significant predictor of vaccination intention. The differences between countries are discussed.

CONCLUSIONS

The study results deliver suggestions for developing appropriate vaccine uptake programs and campaigns that should consider presenting the positive outcomes of vaccines via official sources and traditional media based on scientific evidence and medical professionals' knowledge.

Knowledge, attitudes and demographic drivers for COVID-19 vaccine hesitancy in Malawi

This study assessed the association among knowledge, attitudes and uptake of COVID-19 vaccine in Malawi, examining demographic factors influencing these variables. The study employed a quantitative research design. It thus sampled 394 participants from Malawi's three districts of Zomba, Dowa and Nkhatabay. Results showed that 163 (41.4%) participants had low levels of knowledge of COVID-19 vaccine, 231 (58.6%) had high levels of knowledge, 237 (60.2%) had a positive attitude, and 156 (39.8%) had a negative attitude towards the COVID-19 vaccine. On vaccine uptake, the study found that only 29 (17%) male and 52 (23%) female participants had received the vaccine. Further, participants with low levels of knowledge and a positive attitude towards the vaccine were 5.9 times more likely (p-value = 0.001) to be vaccinated than those with low levels of knowledge and negative attitudes towards the vaccine. On the other hand, those with high knowledge and a positive attitude towards the vaccine were 8.2 times more likely (p-value < 0.001) to be vaccinated compared to those with low knowledge and negative attitudes towards the vaccine. The findings highlight the importance of vaccine-related knowledge and attitudes in shaping uptake and reveal disparities across demographic groups. To improve vaccination coverage in Malawi, targeted interventions focusing on enhancing COVID-19 vaccine knowledge, addressing attitudinal barriers, and countering misinformation are needed. Strategies should be tailored to reach populations with lower uptake, such as males, younger adults, and those with lower education levels. Strengthening public health messaging, engaging community leaders, and building trust in healthcare systems are crucial for promoting widespread acceptance and uptake of COVID-19 vaccines in Malawi.

Meaningful Media Experiences and Vaccination Message Communication: An Experimental Study with Vaccine-Hesitant Individuals

Guided by the eudaimonic media and the health persuasion literature, the current study explores how meaningful emotions elicited from entertainment media exposure decreases anti-vaccination attitudes among vaccine-hesitant individuals. Results of a between-subjects experiment (N = 409) showed that participants who viewed meaningful music videos (vs. neutral videos) and vaccination messages embedded in the user-generated comments reported more empathy, less reactance, and less anti-vaccination attitudes. Multigroup analysis revealed that this association was held for participants who were hesitant about whether they would get fully vaccinated, but not for participants who were determined to not get vaccinated. Theoretical and practical implications were discussed.

Important Barriers to COVID-19 Vaccination Among African Americans in Black Belt Region

BACKGROUND

To identify important barriers to COVID-19 vaccination among African Americans living in the Black Belt region.

METHODS

A cross-sectional, web-based questionnaire survey was conducted using best-worst scaling case 1 (the object case). Thirty-two potential barriers to COVID-19 vaccination were identified from the literature and confirmed by an expert. A nested balanced incomplete block design was used to generate 62 sets of 16 choice tasks. Each choice task included six barriers. Participants were asked to choose the most and least important barriers to their COVID-19 vaccination in each choice task of one set. The natural logarithm of the square root of best counts divided by the worst counts of each barrier was calculated to rank the importance of barriers.

RESULTS

Responses from a total of 808 participants were included. Among 32 barriers to COVID-19 vaccination, the five most important barriers were "safety concern of COVID-19 vaccines," "rapid mutation of COVID-19," "ingredients of COVID-19 vaccines," "Emergency Use Authorization (Fast-track approval) of COVID-19 vaccines," and "inconsistent information of COVID-19 vaccines." On the other hand, the five least important barriers were "religious reasons," "lack of time to get COVID-19 vaccine," "no support from my family and friends," "political reasons," and "fear of the needle."

CONCLUSIONS

Important barriers to the COVID-19 vaccination for African Americans living in the Black Belt region centered around the issues that could be resolved by communication strategies.

Vaccination impact on impending HIV-COVID-19 dual epidemic with autogenous behavior modification: Hill-type functional response and premeditated optimization technique

An HIV-COVID-19 co-infection dynamics is modeled mathematically assimilating the vaccination mechanism that incorporates endogenous modification of human practices generated by the COVID-19 prevalence, absorbing the relevance of the treatment mechanism in suppressing the co-infection burden. Envisaging a COVID-19 situation, the HIV-subsystem is analyzed by introducing COVID-19 vaccination for the HIV-infected population as a prevention, and the "vaccination influenced basic reproduction number" of HIV is derived. The mono-infection systems experience forward bifurcation that evidences the persistence of diseases above unit epidemic thresholds. Delicate simulation methodologies are employed to explore the impacts of baseline vaccination, prevalence-dependent spontaneous behavioral change that induces supplementary vaccination, and medication on the dual epidemic. Captivatingly, a paradox is revealed showing that people start to get vaccinated at an additional rate with the increased COVID-19 prevalence, which ultimately diminishes the dual epidemic load. It suggests increasing the baseline vaccination rate and the potency of propagated awareness. Co-infection treatment needs to be emphasized parallelly with single infection medication under dual epidemic situations. Further, an optimization technique is introduced to the co-infection model integrating vaccination and treatment control mechanisms, which approves the strategy combining vaccination with awareness and medication as the ideal one for epidemic and economic gain. Conclusively, it is manifested that waiting frivolously for any anticipated outbreak, depending on autogenous behavior modification generated by the increased COVID-19 prevalence, instead of elevating vaccination campaigns and the efficacy of awareness beforehand, may cause devastation to the population under future co-epidemic conditions.

Occupational Health Providers' Perceptions of Employee Vaccine Hesitancy

OBJECTIVE

This study examined the perspectives of occupational health providers (OHPs) on the most frequently encountered clinically relevant reasons for employee vaccine hesitancy.

METHODS

We conducted an anonymous, online, cross-sectional survey of US OHPs ( N = 217). The survey asked OHPs about the major reasons that employees cite for being unwilling to receive the following three categories of vaccines: COVID-19, annual influenza, and others relevant to the workplace.

RESULTS

Concern about adverse effects was the most frequently reported reason for employee vaccine hesitancy for each vaccine category. Mistrust was reported more frequently for COVID-19 than for the influenza vaccine or other vaccines (χ 2P < 0.05). Targets of employee mistrust included government and researchers or scientists, but mistrust of healthcare providers was uncommon.

CONCLUSIONS

These results can be used to inform interventions to address vaccine hesitancy in the occupational health setting.

Gap between cognitions and behaviors among children's guardians of influenza vaccination: The role of social influence and vaccine-related knowledge

The seasonal influenza vaccine coverage remains suboptimal among children even though guardians expressed high willingness to vaccinate their children. This study aimed to determine the association between vaccine hesitancy and uptake to facilitate vaccination; thus, bridging the gap. A cross-sectional design, using stratified cluster random sampling, was conducted among guardians of 0-59-month-old Chinese children from July to October in 2019. A structural equation model was applied to explore the interrelationships between factors including vaccine hesitancy, vaccination, social influence, and relative knowledge among guardians. Of the 1,404 guardians, 326 were highly hesitant to vaccinate their children, 33.13% (108/326) of whom had vaccinated their children. Moreover, 517 and 561 guardians had moderate and low vaccine hesitancy, with corresponding vaccine coverage of 42.75% (221/517) and 47.95% (269/516). Guardians' gender, age, and education level were demographic variables with significant moderating effects. Social influence considered impact of communities, family members, friends, neighbors, healthcare workers, bad vaccination experience and sense on price. Actual vaccine uptake was negatively significantly associated with hesitancy (β = -0.11, p < .001) with positive association with social influence (β = 0.61, p < .001). Vaccine hesitancy was negatively significantly associated with relative knowledge (β = -2.14, p < .001) and social influence (β = -1.09, p < .001). A gap is noted between cognitions and behaviors among children's guardians regarding influenza vaccination. A comprehensive strategy including emphasizing benefits of the influenza vaccination, risk of infection, and ensuring high vaccine confidence among healthcare workers can help transform the willingness to engage in the behavior of vaccination.

Association between Gross National Income per capita and COVID-19 vaccination coverage: a global ecological study

BACKGROUND

Coronavirus 2019 (COVID-19) pandemic has claimed over six million lives and infected more than 650 million people globally. Public health agencies have deployed several strategies, including rolling out vaccination campaigns to curb the pandemic, yet a significant proportion of the global population has not received the COVID-19 vaccine. We assessed differences in COVID-19 vaccination coverage by Gross National Income (GNI) per capita of WHO members (i.e., countries, areas, and territories, n = 192) and by WHO member regions (n = 6).

METHODS

Using an ecological study design, we analyzed publicly available data from the WHO website merged with the World Bank's GNI per capita data. We included a total of 192 WHO members and six WHO regions in the analysis. We utilized negative binomial regression to assess the associations between the GNI per capita and COVID-19 vaccination coverage (cumulative number of persons fully vaccinated and/or received at least one dose of the vaccine per 100 population), and ANOVA test to assess the differences in vaccination coverage per WHO regions.

RESULTS

Low GNI per capita WHO members had significantly lower full vaccination coverage (aRR 0.30, 95% CI 0.22-0.40) compared to high GNI per capita WHO members. These members were also 66% less likely to receive at least one dose of the vaccine (aRR 0.34, 0.26-0.44) relative to high GNI per capita WHO members. Africa region had a significantly lower fully vaccination coverage (aRR 0.71, 95% CI 0.36-0.54) and received at least one dose of the COVID-19 vaccine (aRR 0.78, 95% CI 0.62-0.99) than Europe region. Conversely, the Western Pacific region had significantly higher fully vaccination coverage (aRR 1.40 95% CI 1.12-1.74) and received at least one dose of COVID-19 vaccines (aRR 1.40 95% CI 1.14-1.73) relative to European region.

CONCLUSION

WHO members with low GNI per capita and the African region reported significantly lower COVID-19 vaccination coverage than those with high GNI per capita or other regions. Efforts to strengthen and promote COVID-19 vaccination in low-income WHO countries and African region should be scaled up.

Motivators and Barriers to COVID-19 Research Participation at the Onset of the COVID-19 Pandemic in Black Communities in the USA: an Exploratory Study

INTRODUCTION

Black individuals in the USA continue to be underrepresented in clinical trials with low participation rates in COVID-19 research studies. Identifying participation barriers is necessary as we develop more vaccines and other treatments to address SARS-CoV-2 and associated sequelae. The purpose of this explorative, qualitative study is to apply the theory of planned behavior to understand motivators and barriers to COVID-19 research participation at the early stages of the COVID-19 pandemic. Understanding these factors is important to ultimately lead to increased vaccination rates among Black individuals, especially in strategies that increase preparedness in response to public health emergencies.

METHODS

A phenomenological qualitative study design was conducted between May and September 2020 among 62 Black participants. The participants were purposefully selected from vulnerable subgroups of the Black population: essential workers, young adults, parents, and individuals with underlying medical conditions. An inductive-deductive content analysis approach was used to analyze the interview data.

RESULTS

Majority (54.8%) reported willingness to participate in COVID-19 research. The following themes emerged from the interviews: (1) positivity toward research exists yet fear and distrust remain; (2) views toward COVID-19 research vary; (3) motivators to COVID-19 research participation; (4) barriers to COVID-19 research participation; and (5) potential strategies to increase COVID-19 research participation.

CONCLUSIONS

Based on our findings, majority of the participants reported willingness to participate in research with observational research being the most commonly cited type of research. Providing data on the attitudes and perspectives of Black individuals and their intentions for COVID-19 research participation using TPB informs intervention targets for healthcare providers and policy makers for an equitable emergency response. Our results suggest improved communication on the research process, research opportunities, and participant testimonial through trusted sources could increase the likelihood of participation. This is especially important as we continue through the pandemic and new treatments for COVID-19 vaccines become readily available.

The predictors of the intention to receive Covid-19 vaccine using the health belief model and theory of planned behavior in South Khorasan province

BACKGROUND

Widespread vaccination coverage in the shortest time is one of the most effective ways for controlling the COVID-19 pandemic. Factors affecting people's intention to get the COVID-19 vaccine are of great importance. The present study aimed to investigate the predictors of the intention to receive the Covid-19 vaccine based on the constructs of the health belief model (HBM) and theory of planned behavior (TPB) in South Khorasan Province.

MATERIALS AND METHODS

In this cross-sectional-analytical study, 320 people over 18 years in South Khorasan province were randomly selected by cluster sampling method in 2021. The data was collected by a researcher-made questionnaire, including demographic information (9 questions), and the constructs of the health belief model (19 questions), and the theory of planned behavior (13 questions), using the self-report method. Finally, data were analyzed using t-test, ANOVA, linear regression, and Pearson correlation tests.

RESULTS

The mean age of the study participants was 36.57 ± 11.56 with a range of 18-66 years. In the regression model, perceived susceptibility (β = 0.247, P = 0.003), perceived severity (β = 0.247, P = 0.003) from HBM, attitude (β = 0.247, P = 0.003), and perceived behavioral control (β = 0.247, P = 0.003) from TPB were significant predictors of the intention to get the Covid-19 vaccine. The constructs of the two models were able to explain 33% of the variance of the intention to receive the Covid-19 vaccine.

CONCLUSIONS

The study findings reveal that HBM and TPB can predict factors affecting an individual's intention to receive the vaccine. The results can be utilized to design interventions with the aim of increasing vaccine uptake.

Identifying barriers to vaccination intention at walk-in vaccination facilities in deprived neighbourhoods: A cross-sectional survey

OBJECTIVES

Low COVID-19 vaccination adherence in deprived neighbourhoods is problematic since the prevalence of chronic diseases associated with mortality rates due to COVID-19 is higher in these populations. The aim of this study is to provide an insight about beliefs and considerations relating to vaccination intention among inhabitants of deprived neighbourhoods in the Netherlands.

DESIGN

Cross-sectional survey.

SETTING

Easily accessible vaccination facilities at markets in deprived neighbourhoods in the Netherlands.

PARTICIPANTS

Participants were recruited at three vaccination facilities that were set up at markets in deprived neighbourhoods in Rotterdam. A total of 124 surveys were retained for analysis.

MAIN OUTCOME MEASURE

Intention to get vaccinated against COVID-19.

RESULTS

The survey was filled out by 124 respondents; 62 % had - prior to visiting the easily accessible locations - intended to get a COVID-19 vaccine and 38 % were hesitant (22.3 % had doubts and 15.7 % did not plan to get vaccinated). Many people mentioned the convenience of an easily accessible location nearby. At the bivariate level, the influence of information from the family was associated with vaccination intention (p < 0.01). In a logistic regression model, both fear of vaccination and fear of side-effects were significantly associated with vaccination intention (ORs 0.56 (CI 0.35-0.89) and 0.47 (CI 0.30-0.73)).

CONCLUSION

The accessibility of a vaccination facility, family influence and fear are relevant factors for the intention to get vaccinated against COVID-19 in people living in deprived neighbourhoods. Interventions should address these factors in order to increase vaccination uptake.

Mass behaviour change amid COVID-19: How public health information and social norms explain the transformation

COVID-19 is a severe and ongoing threat globally, with the spread disrupting lives and society. Despite the developments of vaccines, the key measure to reduce the transmission of variants has stemmed from mass changes to personal behaviours. COVID-19 pandemic offers a unique context, where the protection behaviours enacted by an individual are necessary to keep the community safe. A social psychological perspective can be used to understand the reasons for adherence to policies and determine what other factors can shape preventive behaviours. To resolve this, in partnership with health consumers we use an online survey, with the findings substantiating preventive behaviours are positively related to COVID-19 information access and descriptive norms. Additionally, findings demonstrate the mediating role of injunctive norms on preventive behaviour suggesting that policy makers can influence decision-making by promoting health information that provides guidance on acceptable behaviours, but also demonstrates subsequent success. The integrity of the model is substantiated by partial least squares (PLS) testing.

Investigating the Psychological, Social, Cultural, and Religious Predictors of COVID-19 Vaccine Uptake Intention in Digital Age: A Media Dependency Theory Perspective

Media exposure to health communication contents related to the COVID-19 pandemic alone is inadequate to measure the influence of media on individuals in adopting precautionary behaviors against COVID-19, such as vaccine uptake. Certain individuals may pay attention to and be influenced by communication content. However, literature has suggested other instrumental determinants in developing and adopting health precautionary measures, such as culture or religion, especially regarding vaccination. In times of crisis, such as the COVID-19 pandemic, it is valuable to examine the interrelationships among psychological, sociocultural, and informational factors. This can provide valuable insights for policymakers in developing effective communication strategies. Drawing an analogy between the Media dependency theory (MDT) and the Theory of Planned Behavior (TPB) model, this study unravels the factors underpinning the COVID-19 vaccine uptake intention among Pakistanis. The study utilized a cross-sectional research design and employed a survey method to gather data from a sample of 993 participants. The findings obtained from the PLS-SEM analysis confirmed that individuals relied on both traditional and social media to cope with the COVID-19 pandemic. The findings show that individuals rely more on the informational content disseminated through conventional media channels. The findings also suggest that individuals from Asian countries, such as Pakistan, tend to be more inclined toward collectivism. The findings about the moderating role of religiosity suggest that religious beliefs significantly shape individuals' reliance on traditional media. Hence, this study has uniquely contributed to public health and media management by providing a strategy for managers to address disseminating misinformation related to religion and its impact on vaccination-related health issues. The study has theoretically confirmed the principles of media dependency theory. As a result, it is recommended that various information sources be utilized to cultivate resilience among individuals to manage health crises effectively.

Examining health sciences students' intention to uptake COVID-19 vaccination using the theory of planned behavior

To examine the association between the theory of planned behavior (TPB) constructs and Health Sciences students' intentions to receive COVID-19 vaccination. A cross-sectional study was conducted in Saudi Arabia by recruiting Health Sciences students as participants. Using Structural Equation Modeling (SEM), the proposed TPB model was evaluated. The sample of 505 individuals consisted of more males (n = 275; 54.5%) than females and was relatively young (88% were between the ages of 18 and 30). The suggested TPB model explained 78.2% of the variation in intention to get COVID-19 immunization. We found that greater levels of perceived behavioral control (β = 1.58, p < .001) and attitude (β = .44, p < .001) strongly predicted increased vaccination intentions. The subjective norm construct was not a significant predictor of vaccination intentions (β = 0.06, p = .34). The findings of this study indicate that the TPB can be utilized effectively to obtain insight into the factors associated with COVID-19 adherence and help in the development of effective COVID-19 intervention strategies.

A population-based paediatric Covid-19 vaccination progress and outcomes: The Malta case

Background

Covid-19 is still pandemic with population vaccination, including among children, remaining the mainstay for hastening the exit from the pandemic. The article provides an insight in Malta's national paediatric vaccination modus operandi, vaccination uptake, and epidemiological trends while exploring geographical social inequalities among the ≤ 15 years cohort up till end of August 2022.

Methods

The Vaccination Coordination Unit in Malta's only regional hospital provided an account of the strategic roll-out along with anonymised cumulative vaccination doses by age band and district. Descriptive and multivariant logistic regression analyses were performed.

Results

By mid-August 2022, 44.18% of the under 15's population had received at least 1 vaccine dose. A bi-directional relationship was observed between increased cumulative vaccination and reported Covid-19 cases until early 2022. Central vaccination hubs were set up with invitation letters and SMSs sent to parents. Children residing in the Southern Harbour district (OR: 0.42, P < 0.01) had the highest full vaccination uptake (46.66%) as opposed to the Gozo district (lowest at 27.23%; OR: 0.3, P = 0.01).

Conclusion

Successful paediatric vaccination is not only dependent on easily accessible vaccination but also on vaccine effectiveness against variants, as well as population characteristics, with potential geographical social inequalities hindering uptake.

Attitudes towards HPV and COVID school-entry policies among adults living in Puerto Rico

Prior to the COVID pandemic, Puerto Rico (PR) had one of the highest Human Papillomavirus (HPV) vaccine rates in the United States. The COVID pandemic and administration of COVID vaccines might have impacted attitudes toward HPV vaccination. This study compared attitudes toward HPV and COVID vaccines with respect to school-entry policies among adults living in PR. A convenience sample of 222 adults (≥21 years old) completed an online survey from November 2021 to January 2022. Participants answered questions about HPV and COVID vaccines, attitudes toward vaccination policies for school-entry, and perceptions of sources of information. We assessed the magnitude of association between the agreement of school-entry policies for COVID and HPV vaccination by estimating the prevalence ratio (PR_adjusted) with 95% Confidence Intervals (95% CI). The most trusted source of information for HPV and COVID vaccines were healthcare providers (42% and 17%, respectively) and the CDC (35% and 55%, respectively), while the least trusted were social media (40% and 39%, respectively), and friends and family (23% n = 47, and 17% n = 33, respectively). Most participants agreed that HPV (76% n = 156) and COVID vaccines (69% n = 136) should be a school-entry requirement. Agreement with school policy requiring COVID vaccination was significantly associated with agreement of school policy requiring HPV vaccination (PR_adjusted:1.96; 95% CI:1.48-2.61) after controlling for potential confounders. Adults living in PR have an overall positive attitude about mandatory HPV and COVID vaccination school-entry policies, which are interrelated. Further research should elucidate the implications of the COVID pandemic on HPV vaccine attitudes and adherence rates.

COVID-19 Vaccination under Conditions of War in Ukraine

The COVID-19 pandemic, which spread around the world in 2020, changed the lives of millions of people and affected the life and functioning of all countries and people without exception. With the emergence of the opportunity to be vaccinated against COVID-19, the problem of making a decision about vaccination also appeared. But it has become increasingly clear that the coronavirus is moving into the group of annual viral epidemic diseases that occur every year in different countries during the seasonal wave of acute respiratory viral infections. The ongoing COVID-19 pandemic against the background of the adoption of serious quarantine measures indicates the need for large-scale vaccination of the population as the most effective way to protect against COVID-19. In this article, we pay special attention to vaccination, as the main factor in ensuring health, reducing the morbidity and severity of the course of the COVID-19 disease, and an important task of the state and modern public administration.

COVID-19 vaccine hesitancy among health workers in rural Uganda: A mixed methods study

Background

COVID-19 vaccination is the latest preventive intervention strategy in an attempt to control the global pandemic. Its efficacy has come under scrutiny because of break through infections among the vaccinated and need for booster doses. Besides, although health workers were prioritized for COVID-19 vaccine in most countries, anecdotal evidence points to high levels of reluctance to take the vaccine among health workers. We assessed COVID-19 vaccine hesitancy among health workers in Dokolo district, northern Uganda.

Methods

This was a mixed-method, cross-sectional descriptive study. A customised self-administered data collection tool was used to collect quantitative data on characteristics, vaccination status and factors for or rejection of vaccine uptake. We conducted multivariable logistic regression to assess the association between selected exposures and vaccine hesitancy using Stata version 15. Conversely, qualitative data were collected using key informant interviews (KIIs) among 15 participants that were purposively selected. Data were analysed using thematic content analysis with the help of NVivo 12.0.

Results

Of the 346 health workers enrolled, (13.3% [46/346]) were vaccine hesitant. Factors associated with vaccine hesitancy included fear of side effects (Adjusted Odds Ratio [AOR]: 2.55; 95% Confidence Interval [95%CI]: 1.00, 6.49) and health workers' lack of trust in the information provided by health authorities (AOR: 6.74; 95% CI: 2.43, 18.72). Similar factors were associated with vaccine hesitancy when we used the vaccine hesitancy score. Fear of side effects, distrust in vaccine stakeholders, and lack of trust in the vaccine were barriers to COVID-19 vaccination among health workers.

Conclusion

A small proportion of health workers were found to be hesitant to take the COVID-19 vaccine in this study. The paucity of COVID-19 vaccine safety information, which eroded the health workers' trust in the information they received on the vaccine, was responsible for health workers hesitancy to take up the vaccine in Uganda.

[Sharing information on COVID-19 vaccination: quantitative online survey on actors, content, sources, and motives]

BACKGROUND

A person's opinion about COVID-19 vaccination and their decision for or against the vaccination are determined, among other things, by the information they receive. Therefore, it seems crucial to examine the phenomenon of information sharing in the context of COVID-19 vaccination. The study explores who shares which information about vaccinations with whom, how the sharing of information is related to the seeking of information from various sources, and what the motives are.

METHOD

From 19 June to 13 July 2021, we conducted an online survey with 833 people using the German non-representative Social Sciences' (SoSci) panel. The questionnaire assessed information sharing with strangers and the social environment, the content, and the motives as well as the sources of information. The responses of 828 people were evaluated using descriptive statistics and multiple linear regression analyses.

RESULTS

Older people, women, and unvaccinated individuals were more likely to share information about COVID-19 vaccination. Information was more often shared in the social environment than with strangers. People shared information about benefits and risks of the vaccination as well as their own experiences with vaccinations. People who research websites of health authorities were more likely to share information about the benefits of vaccinations and their own experiences, while people using YouTube or messenger services were more likely to share information about risks. The motives for sharing information are to help others, social exchange, to raise awareness, to gain status, and the fear of being attacked or judged.

CONCLUSION

Information sharing on COVID-19 vaccination is complex in terms of content and motivation. In order to promote vaccination readiness, the range of information offered by public health departments should be expanded and the population's health literacy should be strengthened.

Implications for COVID-19 vaccine uptake: A systematic review

BACKGROUND

Globally, increasing coronavirus disease (COVID-19) vaccination coverage remains a major public health concern in the face of high rates of COVID-19 hesitancy among the general population. We must understand the impact of the determinants of COVID-19 vaccine uptake when designing national vaccination programmes. We aimed to synthesise nationwide evidence regarding COVID-19 infodemics and the demographic, psychological, and social predictors of COVID-19 vaccination uptake.

METHODS

We systematically searched seven databases between July 2021 and March 2022 to retrieve relevant articles published since COVID-19 was first reported on 31 December 2019 in Wuhan, China. Of the 12,502 peer-reviewed articles retrieved from the databases, 57 met the selection criteria and were included in this systematic review. We explored COVID-19 vaccine uptake determinants before and after the first COVID-19 vaccine roll-out by the Food and Drug Authority (FDA).

RESULTS

Increased COVID-19 vaccine uptake rates were associated with decreased hesitancy. Concerns about COVID-19 vaccine safety, negative side effects, rapid development of the COVID-19 vaccine, and uncertainty about vaccine effectiveness were associated with reluctance to be vaccinated. After the US FDA approval of COVID-19 vaccines, phobia of medical procedures such as vaccine injection and inadequate information about vaccines were the main determinants of COVID-19 vaccine hesitancy.

CONCLUSION

Addressing effectiveness and safety concerns regarding COVID-19 vaccines, as well as providing adequate information about vaccines and the impacts of pandemics, should be considered before implementation of any vaccination programme. Reassuring people about the safety of medical vaccination and using alternative procedures such as needle-free vaccination may help further increase vaccination uptake.

COVID-19 vaccination status in Germany: Factors and reasons for not being vaccinated (yet)

Introduction

The COVID-19 pandemic has demonstrated that effective vaccines constitute a central element of successful pandemic control. Although everyone in Germany has had the opportunity to receive a COVID-19 vaccine, some people remain hesitant or refuse to get vaccinated. To address this phenomenon as well as to examine the unvaccinated population more closely, the present study investigates (RQ1) factors explaining the COVID-19 vaccination status (RQ2) trust in different types of COVID-19 vaccines, and (RQ3) people's specific reasons for not getting vaccinated against COVID-19.

Methods

We base our findings on a representative survey that we conducted in Germany in December 2021 with 1,310 respondents.

Results

In response to the first research question, a logistic regression shows that trust in specific institutions (e.g., medical experts and authorities) is positively related to vaccination status, whereas trust in companies and COVID-19-related social and alternative media consumption decreases the likelihood of being vaccinated. Furthermore (RQ2), while vaccinated people trust mRNA-based vaccines (e.g., BioNTech), most unvaccinated people put greater trust in recently developed protein-based vaccines (e.g., Novavax), albeit on a low level. Finally, our study reveals (RQ3) that the most important reason why people choose not to get vaccinated is that they wish to make their own decisions about their bodies.

Conclusion

Based on our results, we suggest that a successful vaccination campaign should address COVID-19 risk groups and lower income populations, increase trust in different public institutions and newly developed vaccines in advance, establish a multisectoral approach, and debunk fake news and misinformation. Furthermore, since unvaccinated respondents state that the desire to make their own choices about their body is the main reason why they have not gotten vaccinated against COVID-19, an effective vaccination campaign should emphasize the need for general practitioners who have a closer relationship with their patients who, in turn, trust their doctors.

U.S. adults' reasons for changing their degree of willingness to vaccinate against COVID-19

Introduction

COVID-19 vaccines significantly reduce the risk of complications and hospitalizations due to this virus. When COVID-19 vaccines first became commercially available, roughly 30% of U.S. adults reported being hesitant to receive these newly developed vaccines, and 15% said they would not receive the vaccine. However, by May 2021, 19% of adults were vaccine-hesitant, and 13% refused to vaccinate against COVID-19. It is critical to understand why adults' degree of willingness to vaccinate against COVID-19 changed over time to plan for future pandemics and vaccination campaigns.

Methods

We conducted two waves of survey research over five months (January and May 2021) with a panel of 890 U.S. adults. One survey question assessed willingness to vaccinate against COVID-19. The response option included a slider scale ranging from 0 (signifying complete unwillingness) to 10 (complete willingness). We asked participants whose willingness score changed by more than one point to report their rationale for their change in perceptions. We conducted a conventional content analysis on all qualitative responses.

Results

We analyzed qualitative responses for 289 participants, 54.7% of whom had not been vaccinated against COVID-19 by May 2021. Among those who remained unvaccinated, 36.1% reported increased willingness to vaccinate. The most commonly cited reasons for becoming more willing to receive the vaccine include believing that COVID-19 vaccines are safe and effective, protecting against the pandemic, and desiring to return to pre-pandemic life. Reasons for increased COVID-19 vaccine hesitancy include vaccine safety concerns, the low perceived need for the vaccine, distrust in how COVID-19 vaccines are made and of larger institutions such as the government and pharmaceutical companies, and concerns about vaccine effectiveness.

Conclusion

Findings illuminate the rationale behind individuals' changes in their degree of willingness to vaccinate against COVID-19. It is critical to incorporate these considerations in future vaccine rollout initiatives to increase the public's vaccine confidence.

Factors Influencing COVID-19 Vaccine Hesitancy among Patients with Serious Chronic Illnesses during the Initial Australian Vaccine Rollout: A Multi-Centre Qualitative Analysis Using the Health Belief Model

Background: People with chronic illnesses have increased morbidity and mortality associated with COVID-19 infection. The influence of a person's serious and/or comorbid chronic illness on COVID-19 vaccine uptake is not well understood. Aim: To undertake an in-depth exploration of factors influencing COVID-19 vaccine uptake among those with various serious and/or chronic diseases in the Australian context, using secondary data analysis of a survey study. Methods: Adults with cancer, diabetes and multiple sclerosis (MS) were recruited from 10 Australian health services to undertake a cross-sectional online survey (30 June to 5 October 2021) about COVID-19 vaccine uptake, vaccine hesitancy, confidence and complacency and disease-related decision-making impact. Free-text responses were invited regarding thoughts and feelings about the interaction between the participant's disease, COVID-19, and vaccination. Qualitative thematic analysis was undertaken using an iterative process and representative verbatim quotes were chosen to illustrate the themes. Results: Of 4683 survey responses (cancer 3560, diabetes 842, and MS 281), 1604 (34.3%) included free-text comments for qualitative analysis. Participants who provided these were significantly less likely to have received a COVID-19 vaccination than those who did not comment (72.4% and 86.2%, respectively). People with diabetes were significantly less likely to provide free-text comments than those with cancer or MS (29.0%, 35.1% and 39.9%, respectively). Four key themes were identified from qualitative analysis, which were similar across disease states: (1) having a chronic disease heightened perceived susceptibility to and perceived severity of COVID-19; (2) perceived impact of vaccination on chronic disease management and disease-related safety; (3) uncertain benefits of COVID-19 vaccine; and (4) overwhelming information overload disempowering patients. Conclusions: This qualitative analysis highlights an additional layer of complexity related to COVID-19 vaccination decision making in people with underlying health conditions. Appreciation of higher susceptibility to severe COVID-19 outcomes appears to be weighed against uncertain impacts of the vaccine on the progression and management of the comorbid disease. Interactions by clinicians addressing individual factors may alleviate concerns and maximise vaccine uptake in people with significant underlying health conditions.

Prevalence of COVID-19 Vaccine Hesitancy and Its Associated Factors among Chronic Disease Patients in a Resource Limited Setting in Ethiopia: A Cross-Sectional Study

Background. The COVID-19 pandemic disproportionately affects patients with chronic diseases. Thus, chronic disease patients are among the first high-risk population groups to get vaccinated. This might be challenged by vaccine hesitancy as it is one of the top ten global health issues for 2019. Furthermore, vaccination myths and conspiracy theories have been proliferating, and the developing world can readily embrace them, which might cause vaccine hesitancy. However, there is a paucity of evidence regarding chronic illness patient’s willingness to be vaccinated. As a result, the aim of this study is to determine the magnitude of vaccine hesitancy and associated factors among chronic disease patients in Ethiopia. Method. An institutional-based cross-sectional study was conducted among adult ambulatory chronic disease patients who were selected using stratified sampling technique from June 1 to August 1, 2021. Data were collected through a face-to-face interviewer-administered questionnaire. Vaccine hesitancy was measured based on a questionnaire which was adapted from the reviewed literature. Bivariable and multivariable logistic regression was used to identify factors, and variables with $p<0.05$ were considered statistically significant. Result. A total of 422 respondents participated in the survey; the response rate was 99.7%. The mean age of the participants was 45 years  $\pm$  16.95 and 228 (54%) of them were male. Almost half of the respondents (49.5%) were hesitant toward the COVID-19 vaccine. Participants who were male (AOR = 1.56, 95% CI: 1.03, 2.35), having good knowledge about the COVID-19 vaccine (AOR = 1.60 95% CI: 1.06, 2.41) and having a comorbidity (AOR = 3.36, 95% CI: 1.73, 6.56), were factors associated with the acceptance of the COVID-19 vaccine. Conclusion. The level of COVID-19 vaccine hesitancy was high. The COVID-19 vaccine’s acceptability was influenced by being a man, having knowledge about the vaccine and having comorbidities. Furthermore, the most prevalent reason for refusing to take the vaccination is a fear that it may not be safe. As a result, public awareness campaigns should concentrate on delivering more information about the COVID-19 vaccine’s safety and efficacy. Furthermore, it is critical to disseminate accurate information, particularly among women, and to educate people about the vaccine.

A comprehensive survey on the beliefs, perceptions, and clinical manifestations of pre and post Covid-19 vaccinations among physiotherapy students in the United Arab Emirates

The World Health Organization has defined Coronavirus Disease (COVID-19) as an infectious pandemic, caused by a newly discovered SARS-CoV-2 virus. Students relied heavily on the internet, social media, parents, and friends, in addition to medical advice for information on its presentation, complications, prevention, and management. It is evident from the literature that healthcare professionals including students who play an important role in the healthcare system may be lacking important information on COVID-19 vaccinations. Thus, the study aims to identify and compare the pre-post covid-19 vaccination-related essential information among Physical Therapy university students. A cross-sectional survey was conducted among physiotherapy university students in the United Arab Emirates using a self-administrated structured questionnaire. The questionnaire comprised three sections covering beliefs, perceptions, and clinical manifestations of the pre- and post-COVID- 19 vaccination. The survey was shared with more than 300 students through email and social platforms during the time between January 2022 till December 2022. Most of the physiotherapy students believed the vaccines to be safe (71.3%) due to multiple reasons while others did not believe in the effectiveness of the vaccine (28.7%). Some students did report unusual symptoms (painful periods, hair loss, forgetfulness) after the vaccine (10%). Similar findings were reported for family members as well (14%). Students had a positive perception of the vaccine and reported willingness to take it even if not mandatory (68%). Some students did believe in the safety of the vaccine due to multiple reasons while some did not due to fear of long-term side effects and personal choices. The finding of the study could be useful to create confidence as well as awareness among physiotherapy students as they are often invited to aid during medical pandemics such as Covid 19. Also, higher rates of vaccination among healthcare professionals will impart higher acceptance in the medical organization due to safety guidelines. This could also help to counsel other students against fear and apprehension towards the vaccination of such kind in the future.

Generalizing factors of COVID-19 vaccine attitudes in different regions: A summary generation and topic modeling approach

Objective

The goal of this study is to use summary generation and topic modeling to identify factors contributing to vaccine attitudes for three different vaccine brands, with the aim of generalizing these factors across different regions.

Methods

A total of 5562 tweets about three vaccine brands (Sinovac, AstraZeneca, and Pfizer) were collected from 14 December 2020 to 30 December 2021. BERTopic clustering is used to group the tweets into topics, and then contrastive learning (CL) is adopted to generate summaries of each topic. The main content of each topic is generalized into three factors that contribute to vaccine attitudes: vaccine-related factors, health system-related factors, and individual social attributes.

Results

BERTopic clustering outperforms Latent Dirichlet Allocation clustering in our analysis. It can also be found that using CL for summary generation helped to better model the topics, particularly at the center-point of the clustering. Our model identifies three main factors contributing to vaccine attitudes that are consistent across different regions.

Conclusions

Our study demonstrates the effectiveness of deep learning methods for identifying factors contributing to vaccine attitudes in different regions. By determining these factors, policymakers and medical institutions can develop more effective strategies for addressing concerns related to the vaccination process.

Determinants of COVID-19 vaccine hesitancy among students and parents in Sentinel Schools Network of Catalonia, Spain

Vaccine hesitancy is defined as a delay in acceptance of vaccines despite its availability, caused by many determinants. Our study presents the key reasons, determinants and characteristics associated with COVID-19 vaccine acceptability among students over 16 years and parents of students under 16 years and describe the COVID-19 vaccination among students in the settings of sentinel schools of Catalonia, Spain. This is a cross-sectional study that includes 3,383 students and the parents between October 2021 and January 2022. We describe the student's vaccination status and proceed a univariate and multivariate analysis using a Deletion Substitution Addition (DSA) machine learning algorithm. Vaccination against COVID-19 reached 70.8% in students under 16 years and 95.8% in students over 16 years at the end of the study project. The acceptability among unvaccinated students was 40.9% and 20.8% in October and January, respectively, and among parents was proportionally higher among students aged 5-11 (70.2%) in October and aged 3-4 (47.8%) in January. The key reason to not vaccinate themselves, or their children, were concern about side effects, insufficient research about the effect of the vaccine in children, rapid development of vaccines, necessity for more information and previous infection by SARS-CoV-2. Several variables were associated with refusal end hesitancy. For students, the main ones were risk perception and use of alternative therapies. For parents, the age of students, sociodemographic variables, socioeconomic impact related to the pandemic, and use of alternative therapies were more evident. Monitoring vaccine acceptance and refusal among children and their parents has been important to understand the interaction between different multilevel determinants and we hope it will be useful to improve public health strategies for future interventions in this population.

Models of determinants of COVID-19 vaccine hesitancy in non-pregnant and pregnant population: Review of current literature"

Vaccination has proven to be the most effective tool in controlling the COVID-19 pandemic. While pregnant individuals are considered to be a high-risk population and are more likely to experience adverse effects from COVID-19, vaccination rates among pregnant individuals are significantly lower than in the general population. The Health Belief Model (HBM), Theory of Planned Behavior (TPB), 3C model, 5C model, and 5A model have been used to assess vaccination hesitancy behaviors. In this paper, we review the use of each of these models to address vaccine hesitancy, with a focus on the pregnant population and the COVID-19 vaccine. The HBM, TPB, 3C model, and 5C model have demonstrated great versatility in their ability to evaluate, explain, and modify vaccine hesitancy and behavior. Up to date, the HBM and 3C models appear to be the most effective models to study and address vaccination hesitancy within the pregnant persons.

Exposure to Misinformation, Risk Perception, and Confidence towards the Government as Factors Influencing Negative Attitudes towards COVID-19 Vaccination in Malaysia

INTRODUCTION

This study explored exposure to misinformation, COVID-19 risk perception, and confidence towards the government as predictors of negative attitudes toward the COVID-19 vaccine.

METHODS

A cross-sectional survey was carried out from 30 June to 30 August 2021 involving 775 respondents. The survey instrument for the questionnaire was an adaptation from various different studies consisting of five main variables: (1) misinformation about vaccination; (2) risk perception toward COVID-19; (3) attitudes toward the vaccination programme; (4) intention to get vaccinated; and (5) public confidence in the government in executing the vaccination programme.

RESULTS

The results of this study indicate that higher exposure to misinformation led to higher levels of negative attitudes toward the COVID-19 vaccine. When the perceived risk of COVID-19 infection was high, mistrust of vaccine benefits was low but there were also higher worries about the future effects of the vaccine. Confidence in the government was associated with lower negative attitudes toward the COVID-19 vaccine.

CONCLUSION

The results of this study may help develop an understanding of negative attitudes toward vaccinations in Malaysia and its contributing factors.

What Contributes to COVID-19 Vaccine Hesitancy? A Systematic Review of the Psychological Factors Associated with COVID-19 Vaccine Hesitancy

Vaccine hesitancy plays a crucial role in worldwide pandemic-control efforts. The multifaceted nature of vaccine hesitancy entails many psychological factors that are widely discussed in the literature, although few studies specifically compile these factors. Thus, this systematic review aims to synthesize the psychological factors contributing to vaccine hesitancy. As per the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines, a systematic search was conducted on electronic databases PubMed, Scopus, Science Direct, PsycNET, and Web of Science, and a manual search was conducted on Google Scholar. Out of the 2289 articles obtained, 79 studies that met the inclusion criteria were deemed eligible for the review. The findings highlight appraisals of the COVID-19 pandemic, vaccine safety and side effects, vaccine confidence/trust, trust in government and healthcare professionals, scepticism around vaccine production, conspiracy beliefs, emotions, and information and knowledge about the vaccine as the major psychological factors contributing to vaccine hesitancy. Concerningly, misinformation on COVID-19 vaccination spread through social media platforms, increasing vaccine hesitancy. Recommendations for government authorities, healthcare professionals, and implications for future research are also outlined.

Healthcare Workers and Nonhealthcare Workers Pro-Vaccination Attitude and Its Associated Factors towards COVID-19 Vaccine Globally: A Systematic Review and Meta-Analysis

Introduction

Coronavirus disease 2019 (COVID-19) pandemic has not been managed and controlled globally. The aim of this systematic review and meta-analysis were to determine the global pro-vaccination attitude and associated factors towards COVID-19 vaccine among healthcare workers (HCWs) and nonhealthcare workers (non-HCWs).

Methods

Different databases such as PubMed, Scopus, EMBASE, and Google Scholar were used. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 flowchart diagram and PRISMA checklist were used for study screening, selection, and inclusion into this systematic review and meta-analysis. Newcastle-Ottawa Scale (NOS) quality assessment criteria for cross-sectional studies were used to assess the included articles.

Results

A total of 51 studies were included into this systematic review and meta-analysis. The meta-analysis revealed that the global pooled prevalence of pro-vaccination attitude towards COVID-19 vaccine among both HCWs and non-HCWs was 61.30% (95%CI: 56.12, 66.47, I 2 = 99.8%: p=0.000). Subgroup analysis showed that the global pooled prevalence of pro-vaccination attitude towards COVID-19 vaccine was the lowest (59.77%, 95%CI (51.56, 67.98); I 2 = 99.6%, p=0.000) among the HCWs participants and the highest (62.53%, 95%CI (55.39, 69.67); I 2 = 99.8%, p=0.000) among the non-HCWs participants and the lowest (54.31%, 95%CI (43, 65.63); I 2 = 99.5%, p=0.000) for sample size <700 and the highest (66.49%, 95%CI (60.01, 72.98); I 2 = 99.8%, p=0.000) for sample size >700; the lowest (60.70%, 95%CI (54.08, 67.44); I 2 = 93.0%, p=0.000) for studies published in 2020 year and the highest (61.31%, 95%CI (55.93, 66.70); I 2 = 99.8%, p=0.000) for the studies published after 2020 years. From this systematic review, factors significantly associated with pro-vaccination attitude towards COVID-19 vaccine among HCWs were such as age, gender, race, work experience, home location, having no fear of injections, being a non-smoker, profession, presence of chronic illnesses, allergies, confidence in pharmaceutical companies, history of taking influenza vaccine, vaccine recommendation, perceived risk of new vaccines, perceived utility of vaccine, receiving a seasonal flu vaccination in the last 5 years, working in a private hospital, a high perceived pandemic risk index, low vaccine harm index, high pro-socialness index, being in close contact with a high-risk group, knowledge about the virus, confidence in and expectations about personal protective equipment, and behaviors. The level of positive attitude towards COVID-19 vaccine among non-HCWs ranged from 21.40% to 91.99%. Factors associated with the attitude towards COVID-19 vaccine among non-HCWs were such as age, gender, educational level, occupation, marital status, residency, income, ethnicity, risk for severe course of COVID-19, direct contact with COVID-19 at work, being a health profession, being vaccinated against seasonal flu, perceived benefits, cues to actions, having previous history of vaccination, fear of passing on the disease to relatives, and the year of medical study, studying health-related courses, COVID-19 concern, adherence level to social distancing guidelines, history of chronic disease, being pregnant, perceived vaccine safety, having more information about vaccine effectiveness, mandatory vaccination, being recommended to be vaccinated, lack of confidence in the healthcare system to control epidemic, and belief in COVID-19 vaccines protection from COVID-19 infection.

Conclusion

This meta-analysis revealed that the global estimated pooled prevalence of pro-vaccination attitude towards COVID-19 vaccine among both HCWs and non-HCWs was unsatisfactory. Globally, there is a need for a call for action to cease the crisis of this pandemic.

A social ecological approach to identify the barriers and facilitators to COVID-19 vaccination acceptance: A scoping review

BACKGROUND

COVID-19 is an infectious disease caused by the SARS-CoV-2 virus that has caused substantial impact on population health, healthcare, and social and economic systems around the world. Several vaccines have been developed to control the pandemic with varying effectiveness and safety profiles. One of the biggest obstacles to implementing successful vaccination programmes is vaccine hesitancy stemming from concerns about effectiveness and safety. This review aims to identify the factors influencing COVID-19 vaccine hesitancy and acceptance and to organize the factors using the social ecological framework.

METHODS

We adopted the five-stage methodological framework developed by Arksey and O'Malley to guide this scoping review. Selection criteria was based on the PICo (Population, Phenomenon of interest and Context) framework. Factors associated with acceptance and hesitancy were grouped into the following: intrapersonal, interpersonal, institutional, community, and public policy factors using the social ecological framework.

RESULTS

Fifty-one studies fulfilled this review's inclusion criteria. Most studies were conducted in Europe and North America, followed by Asia and the Middle East. COVID-19 vaccine acceptance and hesitancy rates varied across countries. Some common demographic factors associated with hesitancy were younger age, being female, having lower than college education, and having a lower income level. Most of the barriers and facilitators to acceptance of the COVID-19 vaccines were intrapersonal factors, such as personal characteristics and preferences, concerns with COVID-19 vaccines, history/perception of general vaccination, and knowledge of COVID-19 and health. The remaining interpersonal, institution, community, and public policy factors were grouped into factors identified as barriers and facilitators.

CONCLUSION

Our review identified barriers and facilitators of vaccine acceptance and hesitancy and organised them using the social ecological framework. While some barriers and facilitators such as vaccine safety are universal, differentiated barriers might exist for different target groups, which need to be understood if they are to be addressed to maximize vaccine acceptance.

Predicting intentions to get the COVID-19 vaccine in India: An integration of theory of planned behaviour and health belief model

The aim of the study was to determine intention to receive Coronavirus disease-19 (COVID-19) vaccination in India. An integrated model of Theory of Planned behaviour (TPB) and Health Belief Model (HBM) was used. Online survey was conducted in Delhi NCR region to find out the intention to receive vaccination. Data was collected from 845 respondents during 15 February 2021-15 March 2021, just after COVID-19 vaccination became available in the India. Partial Least Square-Structural Equation Modelling was used to establish the relationships. The results of the analysis show that proposed framework is significant and explained 71% variance in intentions. Attitude, subjective norm, perceived behaviour control and self-efficacy from the TPB had direct (or significant independent) effects on intention and perceived benefits, perceived susceptibility from the HBM have indirect effect on the intentions through attitude. The present study can be used to maximise the uptake of vaccination in any future pandemic. This theoretically-driven model can be used to guide health policy makers and health care providers to increase the uptake of vaccination.

Knowledge and Acceptance of the COVID-19 Vaccine for COVID-19 Disease Prevention among the Indian Population: A Mixed-Method Study

Aim: To assess the Knowledge and Acceptance of the COVID vaccine among the Indian population. Materials and methods: The present mixed-method study was conducted in two phases. The first phase: quantitative assessment of knowledge and acceptance for the COVID-19 vaccine using an E survey (N = 606). The second phase: qualitative assessment using semi-structured face-to-face interviews with the study participants (N = 30) and assessment was done using a thematic approach. Study participants were selected using the convenience sampling method. Results: It was found that a large proportion of subjects in the 16−25 year of age group knew the cause of disease. But knowledge about its transmission process was found to be more in >60 years of age gap and almost all the participants in all the age group preferred Covishield. The vaccine acceptance rate was found to be low as compared to the knowledge. Conclusion: Most study participants were found to have satisfactory knowledge, but acceptance rate was comparatively lesser. Hence, more information and awareness campaigns must be launched reassuring the population about vaccine safety.

Factors Associated with Vaccination Intention against the COVID-19 Pandemic: A Global Population-Based Study

Several vaccines have been developed for COVID-19 since the pandemic began. This study aimed to evaluate the factors associated with COVID-19 vaccination intention. A global survey was conducted across 26 countries from October, 2020 to December, 2021 using an online self-administered questionnaire. Demographic information, socio-economic status, and clinical information were collected. A logistic regression examined the associations between vaccine intention and factors such as perceptions and the presence of chronic physical and mental conditions. The sample included 2459 participants, with 384 participants (15.7%) expressing lower COVID-19 vaccination intent. Individuals who identified as female; belonged to an older age group; had a higher level of education; were students; had full health insurance coverage; or had a previous history of influenza vaccination were more willing to receive vaccination. Conversely, those who were working part-time, were self-employed, or were receiving social welfare were less likely to report an intention to get vaccinated. Participants with mental or physical health conditions were more unwilling to receive vaccination, especially those with sickle cell disease, cancer history within the past five years, or mental illness. Stronger vaccination intent was associated with recommendations from the government or family doctors. The presence of chronic conditions was associated with lower vaccine intention. Individuals with health conditions are especially vulnerable to health complications and may experience an increased severity of COVID-19 symptoms. Future research should evaluate the effectiveness of interventions targeting the vaccine perceptions and behaviours of at-risk groups. As such, public awareness campaigns conducted by the government and proactive endorsement from health physicians may help improve COVID-19 vaccination intention.

Mapping the Prevalence of COVID-19 Vaccine Acceptance at the Global and Regional Level: A Systematic Review and Meta-Analysis

Despite the availability of effective and safe vaccines, the acceptance of COVID-19 vaccination is suboptimal. In this meta-analysis we quantified the prevalence estimates of COVID-19 vaccine acceptance with a specific focus on worldwide geographical differences. We searched PubMed, Scopus, Web of Science and PsycInfo up to April 2021 (PROSPERO ID: CRD42021235328). Generalized random-effects linear models with a logit link were used to calculate the pooled estimated rate of vaccine acceptance at both the global and regional level. A meta-regression analysis was performed to assess the association between COVID-19 vaccine acceptance and various characteristics of the studies. Overall, 71 articles yielding 128 prevalence estimates were included. The pooled prevalence of COVID-19 vaccination acceptance rate was 66% (95% CI: 61-71%). This varied by geographic area, ranging from 36% (95% CI: 18-60%) in Africa to 83% (95% CI: 82-84%) in Oceania, and there was high variability between countries (15.4% Cameroon-100% Bhutan). Meta-regression analysis showed that studies that investigated COVID-19 vaccination intentions using multiple choice/scoring gave a vaccine acceptance prevalence lower than studies with only two possible answers (yes/no) (ß: -1.02 95% CI: -1.41 to -0.63). Despite some variation in the estimates, the results showed that one in three people may refuse/delay COVID-19 vaccination.

Impact of societal resilience on vaccine hesitancy and uptake: Lessons learned from the Israeli experience

BACKGROUND

Vaccine hesitancy threatens COVID-19 pandemic management. Increasing vaccine uptake is important to containment of the virus, and achievement of herd immunity.

OBJECTIVE

To identify factors of resilience, distress, and well-being that impact vaccine hesitancy and uptake.

METHOD

A cross-sectional study was conducted during the pandemic's fourth wave. The data were collected by an internet panel company. A representative sample of Israeli residents (N = 2002) answered an online questionnaire. A stratified sampling method was employed regarding geographic distribution, gender, and age. As vaccine hesitancy poses a threat to the effective management of the pandemic, the outcome measures included vaccine hesitancy and uptake (dependent variables), and resilience, distress, and well-being (independent variables).

RESULTS

24% of respondents reported a high level of vaccine hesitancy; 68% received 3 vaccines; 5% did not receive any vaccine. Six predictors together explained 22% of vaccine hesitancy and 15% of vaccine uptake.Path analysis indicated that: (a) Societal resilience was the best predictor of vaccine hesitancy and uptake: the higher the societal resilience, the lower vaccine hesitancy, and the higher vaccine uptake. (b) The higher sense of danger, the higher vaccine hesitancy, and the lower vaccine uptake. (c) The higher level of religiosity, the lower vaccine uptake. (d) The higher the family income, the lower level of vaccine hesitancy.

CONCLUSIONS

Findings suggest that public attitudes are primarily influenced by the degree of trust in the leadership and other components of societal resilience. Further research should investigate the impact of transparency concerning COVID-19 decision-making on vaccine hesitancy and uptake.

The acceptance of COVID-19 vaccine at early stage of development and approval: A global systematic review and meta-analysis

Background

Vaccination seems to be the most effective way to prevent and control the spread of COVID-19, a disease that has adversely impacted the lives of over 7 billion people across the globe. Vaccine hesitancy represents an important threat to combat infectious diseases worldwide. This study aims to inspect the COVID-19 vaccine acceptance rate worldwide and the regional variation of the acceptance rates among the general population and healthcare workers across different territories of the world. In addition, it compares the vaccine acceptance rates between the pre- and post-vaccine approval periods.

Method

A comprehensive systematic review was conducted using PRISMA statements. After quality evaluation, the data from eligible studies were analyzed using the random effect model. Q-test and I2 statistics were used to search for heterogeneity. The publication bias was assessed by using Egger’s test and funnel plot.

Results

The combined COVID-19 vaccine acceptance rate among the general population and healthcare workers (n = 1,581,562) was estimated at 62.79% (95% CI: 58.98–66.60). The acceptance rate substantially decreased from 66.29% (95% CI: 61.24–71.35) to 56.69% (95% CI: 48.68–64.71) among the general population from the pre-to post-vaccine approval periods but remained almost constant at 58.25% (95% CI: 46.52–69.97) among healthcare workers. The acceptance rates also varied in different regions of the world. The highest acceptance rate was found in the South-East Asia region at 70.18% (95% CI: 58.12–82.25) and the lowest was found in African Region at 39.51% (95% CI: 23.42–55.59).

Conclusion

Low COVID-19 vaccine acceptance rate might be a massive barrier to controlling the pandemic. More research is needed to address the responsible factors influencing the low global rate of COVID-19 vaccine acceptance. Integrated global efforts are required to remove the barriers.

It Is a Hoax: Attitude of South-eastern Nigerian Toward COVID-19 and Vaccine: The Need for Social Workers

Different behavioral shifts have been observed among the country's population against the COVID-19 pandemic since its emergence in February 2020 in Nigeria. At first, people were scared of the pandemic and this was reinforced by their response to the National Center for Disease Control measures. As days go by and with the increasing number of confirmed cases of COVID-19 in Nigeria. To reduce the high burden of the pandemic, efforts were made by scientists to produce the COVID-19 vaccine, and Nigeria received about 4 million doses of COVID-19 vaccine in 2021. Thus, it becomes important to investigate the attitude of Nigerians toward COVID-19 and vaccination against COVID-19. To conduct this study, data were sourced using six focus group discussions involving 30 males and females, respectively. Findings revealed that Nigerians have lackadaisical attitude toward COVID-19 and COVID-19 vaccine owing to insincerity on the part of the government, poverty, belief system, low-level of awareness among others. To change the negative attitude of Nigerians toward COVID-19 and the vaccine, social worker interventions are recommended.

Exploring the drivers of COVID-19 protective behaviors among Singaporean tourists to Indonesia using travel bubbles

This study investigats the relationships among positive emotions, perceived threats, protection motivation, coronavirus disease 2019 (COVID-19) vaccination intentions, quarantine-free travel intentions and COVID-19 protective behaviors in the context of quarantine-free travel. Data were collected from Singaporean tourists in Batam and Bintan of Indonesia using travel bubbles. A total of 387 respondents completed the questionnaires. The findings can help tourism managers create and implement market-driven service initiatives to increase positive emotions, protection motivation, and intentions to take quarantine-free travel and decrease perceived threats in order to enable tourists to have accurate COVID-19 protective behaviors.

Understanding the Role of Psychosocial Factors in Pakistani Parents' Hesitancy to Vaccinate Their Kids: The Mediating Role of Knowledge and Mistrust of Science about the COVID-19 Vaccine

Vaccination is a vital component in the battle against outbreaks of infectious diseases. Recognizing parents’ reluctance to vaccinate their children is even more critical now, given the ongoing threat of a COVID-19 pandemic. Conspiracy theories, vaccination safety concerns, parental efficacy and risk perception, and a lack of confidence in science all influence intention. To investigate how these variables interact with vaccination behavior against COVID-19, we developed a model with psychosocial factors serving as the predictor and mistrust in science and vaccine knowledge serving as the mediator. In order to validate the model, the parents’ intentions regarding their children’s vaccination with COVID-19 were used. The study included 454 Pakistani parents who completed an online questionnaire assessing their intention to vaccinate their children. We analyzed the data using structural equation modeling (SEM). A significant level of vaccine hesitation is due to belief in vaccine conspiracy theories, and vaccine safety concerns were investigated. A surprising correlation exists between risk perception and vaccination intentions, followed by parental self-efficacy. It is significant to note that vaccine knowledge mediated conspiracy beliefs, risk perceptions, and intentions fully but partially mediated parental self-efficacy. Conspiracy theories were mediated by a mistrust in science, while perceptions of risk and vaccine safety were partially mediated. The findings of this research were used to develop sensible policy reforms and public health campaigns to encourage vaccination against both common infections such as measles, human papillomaviruses, or pertussis, and novel diseases such as COVID-19.

Identifying the determinants of non-injection of covid-19 vaccine: A qualitative study in Urmia, Iran

Objective

Extensive vaccination coverage is one of the most effective ways to control COVID-19 vaccine, but the tendency to inject the vaccine is always hampered and there are various determinants of non-injection. Hence, the present study was done with the aim of identifying the determinants of non-injection of COVID-19 vaccine with a qualitative approach in the city of Urmia in Iran.

Methods

The present study was conducted with a qualitative approach and conventional content analysis method among 36 people who refused to be vaccinated. Access to participants and data collection was done in person (28 interviews) and online (8 interviews) through targeted sampling and snowball method and semi-structured interviews. Data management was performed using MAXQDA-2018 software and its analysis was performed by Graneheim and Lundman method. Also, Guba and Lincoln criteria were observed to improve the quality of results.

Results

After analyzing the data, 3 main categories and 11 subcategories were obtained including (1) Individual factors (fear of short-term side effects of vaccine, personality traits, distrust of vaccines and pharmaceutical companies), (2) Socio-cultural factors (conspiracy theory, social learning, misconceptions about COVID-19, fatalism), legal and managerial factors (incomplete information, difficult and irregular access to vaccination centers, lack of restrictions and compulsion to be vaccinated, lack of incentives to be vaccinated).

Conclusion

The results showed that various determinants were involved in the non-injection of COVID-19 vaccine. Therefore, efforts to increase vaccination coverage require comprehensive measures at different levels and cross-sectoral cooperation between governmental and non-governmental institutions and organizations.

COVID-19 vaccine uptake among physicians during the second wave of COVID-19 pandemic: Attitude, intentions, and determinants: A cross-sectional study

Background

Developed within a short period of time, the COVID-19 vaccine is not yet widely accepted among the public despite its availability, including by physicians, who are considered a vulnerable group.

Methodology

A descriptive cross-sectional study selected 436 governmental physicians from different specializations, representing four random administrative regions in Egypt. The data were collected through a self-administrated online questionnaire and analyzed using suitable tests.

Results

Out of the studied 436 physicians, 229 (52.2%) [aged 20-30, 284 (65.1%)] were women, 270 (61.9%) were residents, 219 (50.2%) were married, 398 (91.3%) were non-smokers, and 263 (60.3%) were non-frontline caregivers. The majority of the physicians, 227 (52.1%) of them, hesitated to take the vaccine, 236 (54.1%) had not decided on the preferred type of vaccine, and 101 (23.2%) were neutrally confident in the Egyptian healthcare system; 302 (96.3%) had no history of drug or food hypersensitivity. There was no statistically significant (p < 0.05) relationship between the physicians' attitude toward COVID-19 vaccine uptake and the studied demographic variables. There was a statistically significant connection between all of the doctors' intentions to get the COVID-19 vaccine and all of the four attitude domains that were looked at.

Conclusion

The study concluded that a low level of willingness among Egyptian physicians to take the COVID-19 vaccine is a prevalent problem. COVID-19 vaccination hesitancy and non-acceptance were linked to negative attitudes about natural immunity, mistrust of vaccine benefits, and concerns about commercial profiteering.

Attitudes towards Vaccines, Intent to Vaccinate and the Relationship with COVID-19 Vaccination Rates in Individuals with Schizophrenia

Schizophrenia patients are at high risk of developing severe COVID-19 outcomes but recent evidence suggests that they are under-vaccinated. This study explored the role of potential attitudinal barriers by comparing schizophrenia patients with participants from the general population regarding COVID-19 vaccination rates, general attitudes towards vaccines, and willingness to take a COVID-19 vaccine. We conducted a cross-sectional study between April 2021 and October 2021. A total of 100 people with schizophrenia and 72 nonclinical controls were recruited. In our study, individuals with schizophrenia were under-vaccinated, despite similar general attitudes towards vaccination and higher willingness to be vaccinated against COVID-19 compared to nonclinical participants. In patients, negative attitudes toward vaccines were related to higher levels of negative psychotic symptoms and higher levels of paranoid ideation. As a whole, participants with more negative attitudes towards vaccines were less likely to be vaccinated against COVID-19 and had lower levels of trust in institutions. Vaccine hesitancy does not appear to be a major barrier for COVID-19 vaccine uptake amongst people with schizophrenia. This study suggests that disparities in COVID-19 vaccination rates in schizophrenia do not seem related to attitudinal but rather structural barriers.

Message framing and COVID-19 vaccine acceptance among millennials in South India

Vaccine hesitancy and refusal remain a major concern for healthcare professionals and policymakers. Hence, it is necessary to ascertain the underlying factors that promote or hinder the uptake of vaccines. Authorities and policy makers are experimenting with vaccine promotion messages to communities using loss and gain-framed messages. However, the effectiveness of message framing in influencing the intention to be vaccinated is unclear. Based on the Theory of Planned Behaviour (TPB), this study analysed the impact of individual attitude towards COVID-19 vaccination, direct and indirect social norms, perceived behavioural control and perceived threat towards South Indian millennials' intention to get vaccinated. The study also assessed the effect of framing vaccine communication messages with gain and loss framing. Data was collected from 228 Millennials from South India during the COVID-19 pandemic from September to October 2021 and analysed using PLS path modelling and Necessary Condition Analysis (NCA). The findings reveal that attitudes towards vaccination, perceived threat and indirect social norms positively impact millennials' intention to take up vaccines in both message frames. Further, independent sample t-test between the framing groups indicate that negative (loss framed message) leads to higher vaccination intention compared to positive (gain framed message). A loss-framed message is thus recommended for message framing to promote vaccine uptake among millennials. These findings provide useful information in understanding the impact of message framing on behavioural intentions, especially in the context of vaccine uptake intentions of Millennials in South India.
