COVID-19 vaccine literacy: A scoping review

Validation of an Arabic tool for assessing vaccination literacy: A factor and Rasch analysis

Vaccine literacy is a significant part of health literacy. Although several tools have been developed to assess vaccine literacy, such tools are lacking in Arabic. Validating an Arabic version of a tool that evaluates vaccine literacy is critically important, as it would aid in understanding the decision-making process regarding vaccinations among individuals in Arabic-speaking countries. Therefore, the current study aimed to validate an Arabic tool for assessing vaccine literacy in adult vaccination. An online questionnaire was distributed to people throughout Jordan by sharing the questionnaire link via various social media platforms. The reliability and validity of the Arabic version of the vaccination literacy assessment tool (HLVa-Ar) were evaluated using factor analysis and Rasch analyses. The two-factor model generated fit indices were in the acceptable range (χ2/df = 2.48, RMSEA = 0.06, SRMR = 0.05, GFI = 0.94, CFI = 0.97, and TLI = 0.96). Cronbach's alpha for functional Vaccination literacy (VL) and interactive/critical VL were 0.91 and 0.88 respectively. The Rasch analysis indicated acceptable infit/outfit values and high item and person separation reliabilities for the two factors (0.852, 0.868, and 0.771, 0.818 respectively). Overall, the 420 participants displayed a good understanding of the general benefits and importance of vaccination. The HLVa-Ar was shown to be a valid and reliable tool that portrayed a wide range of vaccination literacy levels in the studied sample and provided valuable insights into participants' vaccination knowledge. The findings emphasize the need for developing targeted strategies to improve vaccination literacy and increase vaccination rates.

How well does vaccine literacy predict intention to vaccinate and vaccination status? A systematic review and meta-analysis

This review quantified the association of vaccine literacy (VL) and vaccination intention and status. PubMed, Scopus, and Web of Science were searched. Any study, published until December 2022, that investigated the associations of interest were eligible. For each outcome, articles were grouped according to the vaccine administrated and results were narratively synthesized. Inverse-variance random-effect models were used to compare standardized mean values in VL domain(s) between the two groups: individuals willing vs. unwilling to get vaccinated, and individuals vaccinated vs. unvaccinated. This review of 18 studies shows that VL strongly predicts the vaccination intention while its association with vaccination status is attenuated and barely significant, suggesting that other factors influence the actual vaccination uptake. However, given the scarce evidence available, the heterogeneity in the methods applied and some limitations of the studies included, further research should be conducted to confirm the role of VL in the vaccination decision-making process.

Acceptance of COVID-19 Vaccination and Vaccine Hesitancy Among People with Chronic Diseases in Thailand: Role of Attitudes and Vaccine Literacy Towards Future Implications

Introduction

Vaccination is an important strategy to prevent or reduce hospitalizations and mortality caused by COVID-19 infection. However, some people with chronic diseases are hesitant to get the COVID-19 vaccination.

Objective

This study aimed to assess the acceptance of COVID-19 vaccination and associated factors among people with chronic diseases.

Methods

A cross-sectional online survey was conducted between May and August 2021. A sample of 457 Thai adults living with one or more chronic diseases was drawn from a larger online survey.

Results

Participants were 19 to 89 years old. The three most commonly reported chronic diseases were hypertension, diabetes, and obesity. The acceptance rate of COVID-19 vaccination was 89.1%. Forty-six percent of respondents had received the COVID-19 vaccination, and 43.1% intended to get the vaccine. Reasons for vaccine hesitancy/refusal included concerns about adverse side effects from the vaccines including long-term effects that might complicate their disease condition. Multiple logistic regression analyses revealed that having a bachelor's degree or higher [aOR 4.40; 95% CI: 2.12-9.14], being employed [aOR 2.11; 95% CI: 1.03-4.39], and having positive attitudes [aOR 2.36; 95% CI: 1.69-3.29] and negative attitudes [aOR 0.38; 95% CI: 0.27-0.55] predicted acceptance of the COVID-19 vaccination. Vaccine literacy was significantly associated with acceptance of COVID-19 vaccination in binary logistic regression analyses, but it was not retained in the multiple logistic regression model.

Conclusion

Vaccine literacy and attitudes influence acceptance of COVID-19 vaccination in people with chronic diseases.

Promoting Health Literacy in the Workplace Among Civil Servants: Cross-Sectional Study

Background

In 2022, the World Health Organization highlighted the alarming state of oral health (OH) worldwide and urged action to include OH in initiatives on noncommunicable diseases. The population needs improved OH skills and attitudes and an adequate level of OH literacy (OHL) and general health literacy (HL). The implementation of health promotion actions in the workplace, which is a part of most people's lives, appears to be an opportunity. In France, civil servants have several socioprofessional levels and represent an excellent model with results transposable to the population.

Objective

This study aimed at determining the OHL and HL level of civil servants in France in order to implement specific prevention actions in their workplaces.

Methods

A cross-sectional study of French civil servants was conducted in France from October 2023 to February 2024. Participants completed three validated questionnaires in French: (1) a questionnaire on OH knowledge, (2) the Oral Health Literacy Instrument, French version (OHLI-F; this is composed of reading comprehension and numeracy sections) to assess the OHL level, and (3) the Short Test of Functional Health Literacy in Adults, French version (s-TOFHLA-F) to assess the HL level. The scores for OH knowledge, the OHLI-F, and the s-TOFHLA-F were reported as means (SD) and the 95% CI. These scores were classified into 3 categories: adequate (75-100), marginal (60-74) and inadequate (0-59). ANOVA and binary logistic regression were performed. The OHLI-F reading comprehension and OHLI-F numeracy scores were compared using the Welch 2-sample t test and a paired t test (both 2-tailed). For the correlation matrix, the Pearson correlation and related tests were computed.

Results

A total of 1917 persons completed the 3 questionnaires, with adequate levels of OHL (n=1610, 84%), OH knowledge (n=1736, 90.6%), and HL (n=1915, 99.9%). The scores on the s-TOFHLA-F (mean 98.2, SD 2.8) were higher than the OHLI-F (mean 80.9, SD 7.9) and OH knowledge (mean 87.6, SD 10.5). The OHLI-F was highly correlated with OH knowledge (P<.001), but the OHLI-F and OH knowledge had a low correlation with s-TOFHLA-F (P=.43). The OHLI-F reading comprehension score was significantly higher than the OHLI-F numeracy score (P<.001). Age, education level, and professional category impacted the 3 scores (P<.001). The professional category was a determinant of adequate OHLI-F and OH knowledge scores.

Conclusions

Some French civil servants had inadequate or marginal levels of OH knowledge (n=181, 9.5%) and OHL (n=307, 16%) but none had an inadequate level of HL. Results highlighted the relevance of implementing OH promotion programs in the workplace. They should be nonstandardized, adapted to the literacy level of professional categories of workers, and focused on numeracy skills. Thus, appropriate preventive communication and improved literacy levels are the means to achieve greater disease equity and combat the burden of noncommunicable diseases.

Vaccine literacy, vaccination intention, and their correlation among adults in Mainland China: a cross-sectional study

BACKGROUND

Vaccination is one of the most economic and effective strategies for preventing infectious diseases. However, public intention to be vaccinated is, to a certain degree, influenced by issues related to vaccine hesitancy, anti-vaccine movement, and public concerns about safety and adverse effects. Vaccine literacy is considered as a positive factor in improving vaccination intention, however, the correlation between vaccine literacy and vaccination intention has not been thoroughly investigated in mainland China. This study aims to (1) explore the correlation between vaccine literacy and vaccination intention among adults in mainland China; (2) investigate whether participants could seek out vaccine information on their own initiative and whether they knew basic information of common vaccines.

METHODS

An online cross-sectional survey was conducted on 614 adult participants from 27 May to 8 June 2023 by a convenience sampling. Data were collected by using the questionnaire of demographic characteristics, vaccine literacy, vaccination intention, initiative of seeking out vaccine information, and basic vaccine quiz about common vaccines. Data were analyzed by using IBM SPSS version 24.0 at a significance level of 0.05.

RESULTS

The mean scores of functional, and interactive-critical vaccine literacy were 2.97 ± 0.70 and 2.73 ± 0.66; the vaccination intentions of influenza, hepatitis B, COVID-19 and HPV were 58.5%, 80.0%, 71.3% and 62.9% respectively; interactive-critical vaccine literacy was significantly and positively associated with vaccination intention. The results also showed: 71.4% of the participants could seek out vaccine information on their own initiative, however, a certain proportion of the participants merely knew vaccine names and did not know basic information of common vaccines, especially influenza vaccine and hepatitis B vaccine.

CONCLUSIONS

There is still room for improvement in vaccine literacy, vaccination intention of influenza and HPV vaccines, and basic vaccine information. Based on the significantly positive correlation between interactive-critical vaccine literacy and vaccination intention, it is advisable to harness vaccine literacy to boost vaccination intention by communicating and learning basic information of common vaccines.

The relationship between influenza vaccine hesitancy and vaccine literacy among youth and adults in China

Objectives

The present study aimed to assess influenza vaccine hesitancy and vaccine literacy levels among youth and adults in China, as well as the association between them.

Methods

An online cross-sectional survey was conducted in Mainland China. Participants' total vaccine literacy and three sub-dimension vaccine literacy (knowledge literacy, competence literacy, and decision-making literacy) were assessed by a validated vaccine literacy scale. Having received influenza vaccination in the past three years or intending to accept it in next influenza season indicates less influenza vaccine hesitancy.

Results

Among 997 participants, a sub-optimal vaccine literacy was observed, with a mean score of 66.83 ± 10.27. Regression models 1-4 revealed that participants with middle (aOR: 1.431, P=0.039, 95% CI: 1.018~2.010) or high (aOR: 1.651, P=0.006, 95% CI: 1.157~2.354) total vaccine literacy, as well as those with high competence literacy (aOR: 1.533, P=0.017, 95% CI: 1.079~2.180), or high decision-making literacy (aOR: 1.822, P=0.001, 95% CI: 1.261~2.632) were more likely to have been vaccinated against influenza at least once in past three years. However, those with a high knowledge literacy were associated with a lower influenza vaccine rate (aOR: 0.676, P=0.046, 95% CI: 0.460~0.994). Regression models 5-8 revealed that participants with middle (aOR: 1.661, P=0.008, 95% CI: 1.142~2.414) or high total vaccine literacy (aOR: 2.645, P=0.000, 95% CI: 1.774~3.942), as well as those with middle (aOR: 1.703, P=0.005, 95% CI: 1.177~2.464) or high competence literacy (aOR: 2.346, P=0.000, 95% CI: 1.159~3.461), or high decision-making literacy (aOR: 2.294, P=0.000, 95% CI: 1.531~3.436) were more likely to express the willingness to receive the influenza vaccine in the next influenza season.

Conclusion

The participants' influenza vaccine hesitancy was negatively associated with their total vaccine literacy levels and two of the three sub-dimensions: competence literacy and decision-making literacy. Knowledge literacy suggested a positive or no relationship with influenza vaccine hesitancy.

Factors influencing COVID-19 vaccine uptake among Latinos: A cross-sectional study

Vaccination against COVID-19 can prevent severe illness and reduce hospitalizations and deaths. Understanding and addressing determinants contributing to vaccine uptake among high-risk groups, such as Latinos, are pivotal in ensuring equitable vaccine distribution, promoting health equity, and fostering community engagement to bridge the gap in vaccine acceptance and ultimately enhance public health. This study aimed to examine factors influencing vaccine uptake among Latinos. We conducted a cross-sectional study using an online platform (n = 242). The survey was administered using a multimodal approach. Strategies for recruitment included community outreach, social media, and targeting community networks serving Latinos. Descriptive statistics, chi-square, and multivariable analysis were performed. Overall, 81.4% of respondents had received at least one dose of the COVID-19 vaccine, with 77.0% recommending it and 70.6% believing it to be safe, 66.7% believing in its efficacy, 62.3% able to find trustful information in Spanish or Portuguese, and almost 40% who relied on health organizations as their primary resource for COVID-19 vaccine information. Factors significantly associated with vaccine uptake included higher education level (p<0.001), English level (p = 0.023), living in an urban area (p = 0.048), having insurance (p<0.001), and having a healthcare provider (p = 0.007). Furthermore, belief in vaccine safety and efficacy, trust in public health authorities, concerns about COVID-19, the ability to determine true/false vaccine information during the pandemic, and the availability of trustworthy information in Spanish/Portuguese had statistically significant associations (p<0.05) with COVID-19 vaccine uptake. COVID-19 vaccine uptake differed based on sociodemographic and other modifiable factors. Our findings emphasize the importance of implementing targeted interventions and culturally sensitive communication strategies to improve vaccination uptake among the Latino community in the United States.

Perspectives in the Development of Tools to Assess Vaccine Literacy

Vaccine literacy (VL) is the ability to find, understand, and evaluate vaccination-related information to make appropriate decisions about immunization. The tools developed so far for its evaluation have produced consistent results. However, some dimensions may be underestimated due to the complexity of factors influencing VL. Moreover, the heterogeneity of methods used in studies employing these tools hinders a comprehensive understanding of its role even more. To overcome these limitations, a path has been sought to propose new instruments. This has necessitated updating earlier literature reviews on VL and related tools, exploring its relationship with vaccine hesitancy (VH), and examining associated variables like beliefs, attitudes, and behaviors towards immunization. Based on the current literature, and supported by the re-analysis of a dataset from an earlier study, we propose a theoretical framework to serve as the foundation for creating future assessment tools. These instruments should not only evaluate the psychological factors underlying the motivational aspect of VL, but also encompass knowledge and competencies. The positioning of VL in the framework at the intersection between sociodemographic antecedents and attitudes, leading to behaviors and outcomes, explains why and how VL can directly or indirectly influence vaccination decisions by countering VH and operating at personal, as well as at organizational and community levels.

SARS-CoV-2-Placental effects and association with stillbirth

SARS-CoV-2 has had a significant impact on pregnancy outcomes due to the effects of the virus and the altered healthcare environment. Stillbirth has been relatively hidden during the COVID-19 pandemic, but a clear link between SARS-CoV-2 and poor fetal outcome emerged in the Alpha and Delta waves. A small minority of women/birthing people who contracted COVID-19 developed SARS-CoV-2 placentitis. In many reported cases this was linked to intrauterine fetal death, although there are cases of delivery just before imminent fetal demise and we shall discuss how some cases are sub-clinical. What is surprising, is that SARS-CoV-2 placentitis is often not associated with severe maternal COVID-19 infection and this makes it difficult to predict. The worst outcomes seem to be with diffuse placental disease which occurs within 21 days of COVID-19 diagnosis. Poor outcomes are often pre-dated by reduced fetal movements but are not associated with ultrasound changes. In some cases, there has also been maternal thrombocytopenia, or coagulation abnormalities, which may provide a clue as to which pregnancies are at risk of fetal demise if a further variant of concern is to emerge. In future, multidisciplinary collaboration and cross-boundary working must be prioritised, to identify quickly such a phenomenon and provide clinicians with clear guidance for reducing fetal death and associated poor outcomes. While we wait to see if COVID-19 brings a future variant of concern, we must focus on appropriate future management of women who have had SARS-CoV-2 placentitis. As a placental condition with an infectious aetiology, SARS-CoV-placentitis is unlikely to recur in a subsequent pregnancy and thus a measured approach to subsequent pregnancy management is needed.

COVID-19 Vaccine Acceptance and Hesitancy among Nurses in Thailand: Implications, Challenges, and Future Prospects for Attitudes and Vaccine Literacy

Nurses are healthcare workers at high risk of contracting COVID-19 and are prioritized for COVID-19 vaccination. This study aimed to explore COVID-19 vaccine acceptance, vaccine literacy, and attitudes toward COVID-19 vaccines, and determine factors associated with COVID-19 vaccine acceptance among nurses in Thailand. A cross-sectional survey was conducted using online questionnaires between May and June 2021. A total of 510 nurses were recruited during the pandemic's third wave in Thailand. Data were analyzed using descriptive and inferential statistics. Ten percent (n = 51) of the participants were men, all of whom showed COVID-19 vaccine acceptance. Of the 459 female nurses, 94.8% (n = 435) accepted COVID-19 vaccination and 91.3% (n = 419) reported previous influenza vaccination. In multiple logistic regression models, previous influenza vaccination, interactive-critical vaccine literacy, and attitudes toward COVID-19 vaccines were significant predictors of COVID-19 vaccine acceptance among female nurses in Thailand. Those who had previously received influenza vaccination were more likely to accept COVID-19 vaccination. Higher scores for interactive-critical vaccine literacy and positive attitudes toward the COVID-19 vaccine increased the odds of accepting vaccination, while negative attitudes were associated with decreased vaccine acceptance. Vaccine literacy, together with attitudes toward the COVID-19 vaccine, had a strong positive effect on increasing vaccination acceptance and reducing vaccine hesitancy. The results suggest that policymakers should consider both attitudes and vaccine literacy when establishing prospective strategies for promoting vaccine acceptance among nurses beyond the COVID-19 pandemic.

Identifying Mental Health Literacy as a Key Predictor of COVID-19 Vaccination Acceptance among American Indian/Alaska Native/Native American People

BACKGROUND

This study examines how health literacy and mental health literacy associate with the willingness to receive a COVID-19 vaccination among American Indian/Alaska Native/Native American (AI/AN) people.

METHODS

The data were collected with an online Qualtrics survey in February 2021 (n = 563). A purposive snowball sampling strategy was used by sending recruitment flyers to colleagues and organizations who work with AI/AN communities to share with appropriate potential respondents. We performed linear regression analyses examining the relationships between the willingness to receive a COVID-19 vaccination and socio-demographic characteristics such as age, gender, education, health literacy, mental health literacy, self-rated physical and mental health status, worry about getting COVID-19, perceived COVID-19 susceptibility, and perceived COVID-19 severity.

RESULTS

Mental health literacy and health literacy predicted 30.90% and 4.65% of the variance (R2adjusted) in the willingness to receive a COVID-19 vaccine, respectively. After holding the self-rated physical/mental health status, worry about getting COVID-19, perceived susceptibility, perceived severity, health literacy, and socio-demographics constant, mental health literacy was still a strong predictor (b = 0.03, p < 0.001) for the willingness to receive a COVID-19 vaccine (model R2adjusted = 40.14%).

CONCLUSIONS

We identified mental health literacy as a substantial factor associated with the willingness to receive a COVID-19 vaccination among AI/AN respondents.

Barriers to COVID-19 vaccine uptake: classification and the role of Health Literacy and Media Literacy

Background

Vaccination is one of the most influential and cost-effective health interventions for preventing and reducing COVID-19 diseases. Unfortunately, the majority of the world's population is deprived of vaccination. Health Literacy (HL) and Media Literacy (ML) are essential to the COVID-19 vaccination. The present study investigates the barriers to COVID-19 vaccine uptake, focusing on classification and the roles of HL and ML.

Methods

A cross-sectional study was conducted among people 18-65 years old in Sarab City, located in East Azerbaijan, Iran, between September to October 2020. Multistage cluster sampling was employed to recruit 298 people from Health Care Services Centers (HCCs).

Results

The results of this research demonstrated that about 32.6% of participants reported that they have fully injected COVID-19 vaccines. Also, HL was positively associated with ML (r = 0.214, p < 0.05). Barriers of COVID-19 vaccine uptake were classified into personal, interpersonal, group and organizational, society and decision-making factors. Besides, barriers to the COVID-19 vaccine were significantly correlated with HL (r = -0.298, p < 0.05) and ML (r = 0.266, p < 0.05). Additionally, in the hierarchical regression model, demographic characteristics accounted for 8.2% of the variation in barriers to the COVID-19 vaccine (F = 4.34; p = 0.001), that monthly income (ß = -0.237; p < 0.05) and marriage statues (ß = 0.131; p < 0.05) were statistically associated with low barriers. HL as predictor variables explained an additional 14.4% of variation in barriers of COVID-19 vaccine (F = 53.84; p < 0.001) and ML explained an extra 9.2% of the variation (F = 38.83; p < 0.001). In total, demographic characteristics, HL dimensions and ML were able to explain 31.8% of the variation in barriers to COVID-19 vaccine.

Conclusions

According to the findings, various strategies are needed to increase the COVID-19 vaccination uptake. This is due to the fact that barriers to COVID-19 vaccination uptake are multifactorial. These facts can help health policymakers and healthcare providers design media-based interventions to reduce barriers to COVID-19 vaccination uptake among adults. Enhancing vaccine HL and ML for adults and improving vaccine confidence are of high priority.

Using the COM-B framework to elucidate facilitators and barriers to COVID-19 vaccine uptake in pregnant women: a qualitative study

Since April 2021, COVID-19 vaccines have been recommended for pregnant women. Despite this, COVID-19 vaccine uptake in this group is low compared to the non-pregnant population of childbearing age. Our aim was to understand barriers and facilitators to COVID-19 vaccine uptake among pregnant women in Northern Ireland using the COM-B framework, and so to make recommendations for public health interventions. The COM-B proposes that human behaviour is influenced by the extent to which a person has the capability, opportunity, and motivation to enact that behaviour. Understanding the factors underpinning behaviour through this lens helps discern what needs to change to change behaviour, therefore supporting the development of targeted interventions.This study consisted of eight semi-structured interviews with new/expectant mothers who did not receive a COVID-19 vaccine dose while pregnant since April 2021, and a focus group with five participants who received at least one COVID-19 vaccine dose while pregnant. Interview and focus group data were analysed using semi-deductive reflexive thematic analysis framed by a subtle realist approach. The COM-B was used to categorise codes and subthemes were developed within each COM-B construct.Within Psychological Capability, subthemes captured the need for consistent and reliable COVID-19 vaccine information and access to balanced and jargon-free, risk-benefit information that is tailored to the pregnant individual. The behaviour/opinions of family, friends, and local healthcare providers had a powerful influence on COVID-19 vaccine decisions (Social Opportunity). Integrating the COVID-19 vaccine as part of routine antenatal pathways was believed to support access and sense of familiarity (Physical Opportunity). Participants valued health autonomy, however experienced internal conflict driven by concerns about long-term side effects for their baby (Reflective Motivation). Feelings of fear, lack of empathy from healthcare providers, and anticipated guilt commonly underpinned indecision as to whether to get the vaccine (Automatic Motivation).Our study highlighted that the choice to accept a vaccine during pregnancy generates internal conflict and worry. Several participants cited their concern was primarily around the safety for their baby. Healthcare professionals (HCPs) play a significant part when it comes to decision making about COVID-19 vaccines among pregnant women. HCPs and pregnant women should be involved in the development of interventions to improve the delivery and communication of information.

Coevolution based immunoinformatics approach considering variability of epitopes to combat different strains: A case study using spike protein of SARS-CoV-2

In the recent past several vaccines were developed to combat the COVID-19 disease. Unfortunately, the protective efficacy of the current vaccines has been reduced due to the high mutation rate in SARS-CoV-2. Here, we successfully implemented a coevolution based immunoinformatics approach to design an epitope-based peptide vaccine considering variability in spike protein of SARS-CoV-2. The spike glycoprotein was investigated for B- and T-cell epitope prediction. Identified T-cell epitopes were mapped on previously reported coevolving amino acids in the spike protein to introduce mutation. The non-mutated and mutated vaccine components were constructed by selecting epitopes showing overlapping with the predicted B-cell epitopes and highest antigenicity. Selected epitopes were linked with the help of a linker to construct a single vaccine component. Non-mutated and mutated vaccine component sequences were modelled and validated. The in-silico expression level of the vaccine constructs (non-mutated and mutated) in E. coli K12 shows promising results. The molecular docking analysis of vaccine components with toll-like receptor 5 (TLR5) demonstrated strong binding affinity. The time series calculations including root mean square deviation (RMSD), radius of gyration (RGYR), and energy of the system over 100 ns trajectory obtained from all atom molecular dynamics simulation showed stability of the system. The combined coevolutionary and immunoinformatics approach used in this study will certainly help to design an effective peptide vaccine that may work against different strains of SARS-CoV-2. Moreover, the strategy used in this study can be implemented on other pathogens.

Better to Be Unpaid than COVID-19 Vaccinated! A Qualitative Study on Italian Nurses Suspended from Work without Salary

In Italy, from April 2021, healthcare workers were required to receive the COVID-19 vaccine; if they refused it, an immediate unpaid suspension was implemented until they received the vaccine. Although there are numerous quantitative studies on the factors that influenced vaccine hesitancy during the COVID-19 pandemic, qualitative research on the causes of vaccine refusal is still missing. This research aimed to investigate the phenomenon of nurses who refused to receive COVID-19 vaccination despite being required to do so, as well as the reasons behind their refusal. Furthermore, the actions of those who abandoned this stance were explored. This was a qualitative study involving the methodological approach of grounded theory. Twenty-four nurses were interviewed virtually via Zoom from May to July 2022. Anti-vax behavior-as emerged from nurses' experiences-was based on seven themes: (1) job satisfaction, (2) the main sources of information on COVID-19, (3) the reasons for refusing the COVID-19 vaccine, (4) the attitudes of family members toward the COVID-19 vaccine, (5) previous experience with other vaccines, (6) firm opposition to the vaccine (unvaccinated nurses), (7) reluctant acceptance (vaccinated nurses). It was shown that it is imperative for health authorities to adopt timely, documented, transparent, and consistent communication when carrying out public health campaigns, especially for vaccination.

Influenza Vaccination among Patients with Diabetes or Ischemic Heart Disease in Thailand: Coverage, Knowledge and Associated Factors

An influenza vaccination is recommended for patients with diabetes mellitus (DM) or ischemic heart disease (IHD) to prevent cardiovascular events, but the vaccination coverage remains low. This cross-sectional study sought to investigate vaccination coverage, knowledge level on influenza and factors associated with influenza vaccination in patients with DM or IHD treated at a tertiary hospital in northern Thailand. Patients were interviewed from August to October 2017. Of 150 patients interviewed (51.3% women, mean age of 66.7 ± 8.3 years, 35.3% DM, 35.3% IHD, 29.3% DM and IHD), 45.3% (68/150) were vaccinated against influenza. The mean knowledge score was 9.68 ± 1.35 (total: 11) and did not differ between those receiving the immunization and those who did not (p = 0.056). Two factors remained significantly associated with their vaccination after multivariable logistic regression analysis: knowing their right to receive free vaccinations (adjusted OR 2.32, 95% CI: 1.06-5.10, p-value: 0.035), and needing to be vaccinated (adjusted OR 3.50, 95% CI: 1.51-8.12, p-value: 0.003). Overall, the vaccine coverage was low; less than one-half of patients received the influenza vaccine, but their knowledge level was high. Possessing the right and having a need were two factors associated with vaccination. Such factors should be carefully considered to encourage patients with DM and IDH to receive the influenza vaccination.
