Predicting intention to receive COVID-19 vaccine among the general population using the health belief model and the theory of planned behavior model

COVID-19 vaccine acceptance in the second wave of the pandemic among university students in Ethiopia: application of the health belief model

Background

The first case of COVID-19 virus was reported in Africa on 14 February 2020. The pandemic became more aggressive in the continent during the second wave than the first wave. Promoting vaccination behavior is an unparalleled measure to curb the spread of the pandemic. Regarding this, the health belief model (HBM) is the major model for understanding health behaviors. This study aimed to examine predictors of intended COVID-19 vaccine acceptance in the second wave of the pandemic among university students in Ethiopia using HBM.

Methods

A cross-sectional study was conducted among 423 randomly selected medical and health science students at the University of Gondar from 21 August to 15 September 2020. Analysis of data was performed using STATA 14.0. Linear regression analysis was applied and a p value of less than 0.05 was used to declare statistical significance.

Results

Among the total participants, 293 [72.2% (95.0%: CI: 67.2-76.8)] of them scored above the mean of COVID-19 vaccine acceptance. HBM explained nearly 46.3% (adjusted R2 = 0.463) variance in intention to receive the COVID-19 vaccine. Year of study (β = 0.288; 95% CI: 0.144-0.056), using social media (β = 0.58; 95% CI: 1.546-2.804), existing chronic disease (β = 0.12; 95% CI: 0.042-0.433), perceived overall health condition (β = 0.117; 95% CI: 0.307-0.091), perceived susceptibility (β = 0.58; 95% CI: 1.546-2.804), perceived benefit (β = 0.338; 95% CI: 1.578-2.863), and cues to action (β = 0.49; 95% CI: 0.388-0.99) were significantly associated with intended COVID-19 vaccine acceptance at p value < 0.5.

Conclusion

Approximately, three-quarters of the participants were above the mean score of COVID-19 vaccine acceptance, which is higher compared to previous reports in resource-limited settings. Interventions in this study setting chould include placing emphasis on the risks of acquiring COVID-19, enhancing perceived benefits of COVID-19 vaccination and improving cues to action by advocating COVID-19 vaccination. Our findings also implied that social media health campaigns are significant factor in COVID-19 vaccination behavioral change in this study setting.

Characterization of COVID-19 Vaccine Hesitancy Among Essential Workforce Members of a Large Safety Net Urban Medical Center

OBJECTIVES

Vaccine hesitancy among essential workers remains a significant public health challenge. We examined psychological constructs of perceived susceptibility, threat, and self-efficacy and their associations with COVID-19 vaccine hesitancy among a racially and ethnically diverse essential workforce population.

METHODS

We performed a cross-sectional survey of essential workers from September-December 2020 at a large Los Angeles safety-net medical center as part of a program offering free COVID-19 serology testing. Program participants completed a standardized survey at the time of phlebotomy. Hierarchical logistic regression was utilized to determine factors independently associated with vaccine hesitancy.

RESULTS

Among 1327 persons who had serology testing, 1235 (93%) completed the survey. Of these, 958 (78%) were healthcare workers. Based on expressed intent, 22% were vaccine-hesitant 78% were vaccine acceptors. In our multivariate model, vaccine hesitancy was associated with female gender [aOR = 2.09; 95% CI (1.44-3.05)], African American race [aOR = 4.32; (2.16-8.62)], LatinX ethnicity [aOR = 2.47; 95% CI (1.51-4.05)] and history of not/sometimes receiving influenza vaccination [aOR = 4.39; 95% CI (2.98-6.48)]. Compared to nurses, vaccine hesitancy was lower among physicians [aOR = 0.09; 95% CI (0.04-0.23)], non-nursing/non-physician healthcare workers [aOR = 0.55; 95% CI (0.33-0.92)], and non-healthcare care workers [aOR = 0.53; 95% CI (0.36-0.78)].

CONCLUSIONS

Among a racially/ethnically diverse group of safety net medical center essential workers, COVID-19 vaccine hesitancy was associated with racial/ethnic minority groups, employment type, and prior influenza vaccination hesitancy. Interestingly, we found no association with the Health Belief Model construct measures of perceived susceptibility, threat, and self-efficacy. Psychological constructs not assessed may be drivers of vaccine hesitancy in our population.

"I was having an internal conflict with myself." COVID-19 vaccination decision-making processes among pregnant women

BACKGROUND

Vaccination serves as an efficient primary means of control for infectious diseases. However, in the case of the COVID-19 pandemic, pregnant women within the United States had the lowest rates of COVID-19 vaccination and reported the lowest intent to vaccinate.

OBJECTIVES

To explore the decision-making process for COVID-19 vaccination for people pregnant during the pandemic.

DESIGN

A secondary analysis of data from a mixed-methods study that examined the impact of COVID-19 on experiences of prenatal care, birth support, and delivery in the Southern United States.

METHODS

This study used a descriptive phenomenological approach to thematically analyze in-depth interviews (n = 20) with adult women who were pregnant by January 2020 and had their prenatal care and delivery during the pandemic beginning in March 2020. The transcripts were de-identified, coded, and thematically analyzed to saturation to identify drivers of COVID-19 vaccine decision-making based on COVID-19 vaccination status and timing. Comparative analyses were conducted to assess differences in decision-making processes based on race/ethnicity and parity. Participants also completed a sociodemographic survey that included their COVID-19 vaccination status.

RESULTS

Two themes emerged, the weighing of parallel risks and priorities from different sources resulting in vaccine decisional conflict and the need to reconcile that conflict via multiple strategies. All participants weighed priorities and risks from multiple areas of their lives and described internal conflict around vaccination. Participants described tailoring decisions to household dynamics, reconciling public and private values around vaccination, and the impact of their identities on the decision-making process. While many described concerns over vaccine safety and fetal health, uniquely, many highlighted weighing the impact of prior pregnancy loss history, with some choosing other preventive measures like social distancing or mask-wearing, which they deemed less risky.

CONCLUSION

Pregnant people make complex COVID-19 vaccination decisions, which must be considered in future vaccine messaging and advocacy for this group.

COVID-19 Vaccine Acceptance Among Healthcare Students in Vietnam, Based on Health Belief Model

Introduction

Healthcare students have a high risk of acquiring COVID-19 while practicing in medical facilities, and their health-related decisions might considerably impact the people around them. In the circumstance of many people refusing vaccination, the delay in accepting the COVID-19 vaccine by this group could be a barrier to providing effective immunity to the entire population against the COVID-19 pandemic.

Objective

The study aimed to assess the prevalence of vaccination acceptance and the factors influencing COVID-19 vaccine acceptance among Vietnamese healthcare students.

Methods

A web-based cross-sectional study was conducted among 384 respondents. The chi-square, Fisher's exact, and Mann-Whitney tests were used to assess the association between independent and dependent variables. Binary logistic regression analysis was used to identify the potential determinants of COVID-19 vaccine acceptance. Variables with p values of less than .05 at the 95% confidence interval were considered significant variables.

Results

Out of 384 participants, 91.7% accepted COVID-19 vaccination. Nurse and midwife (odds ratio [OR] = 6.81, confidence interval [CI] = 2.02-22.94, p < .01), perceived normal health status (OR = 15.22, CI = 2.74-84.66, p < .001), perceived good health status (OR = 149.00, CI = 11.08-2003.42, p < .01), COVID-19 infection among relatives or friends (OR = 4.19, CI = 1.77-9.95, p < .01) were predictors for the COVID-19 vaccine acceptance. Participants were less likely to accept COVID-19 vaccination if they reported greater perceived barriers (OR = 0.80, CI = 0.69-0.93, p < .01).

Conclusion

The current study offers helpful information on the factors influencing vaccine acceptance based on the Health Belief Model. The findings could benefit policymakers in establishing effective campaigns to improve the acceptance rate of the COVID-19 vaccine among healthcare students and shorten the time required to achieve herd immunity.

How information processing and risk/benefit perception affect COVID-19 vaccination intention of users in online health communities

Objective

To investigate the relationship among information processing, risk/benefit perception and the COVID-19 vaccination intention of OHCs users with the heuristic-systematic model (HSM).

Methods

This study conducted a cross-sectional questionnaire via an online survey among Chinese adults. A structural equation model (SEM) was used to examine the research hypotheses.

Results

Systematic information processing positively influenced benefit perception, and heuristic information processing positively influenced risk perception. Benefit perception had a significant positive effect on users' vaccination intention. Risk perception had a negative impact on vaccination intention. Findings revealed that differences in information processing methods affect users' perceptions of risk and benefit, which decide their vaccination intention.

Conclusion

Online health communities can provide more systematic cues and users should process information systematically to increase their perceived benefits, consequently increase their willingness to receive COVID-19 vaccine.

Factors Associated with Handwashing Behaviors During the COVID-19 Pandemic: An Analysis of the Community Health Survey in Korea

Introduction

Handwashing is the most effective preventive behavior for coronavirus disease-19 (COVID-19) infection. However, research has shown the lower handwashing behaviors among Korean adults.

Objectives

This study aims to analyze factors associated with handwashing as a preventive behavior for COVID-19 infection based on the health belief model (HBM) and the theory of planned behavior (TPB) behavioral theories.

Methods

This secondary data analysis utilized the Community Health Survey developed by Disease Control and Prevention Agency conducted in 2020. Sampling method was stratified and targeted 900 people living in the territory of each community public health center. In total, 228,344 cases were used in the analysis. Handwashing behavior, perceived susceptibility, perceived severity, subjective norm, and influenza vaccine uptake were used in the analysis. Regression analysis using weighing strategy by stratification and domain analysis was used.

Results

Less washing hand was associated with older age (B = 0.01, p < .001), males (B = 0.42, p < .001), not receiving an influenza vaccine (B = 0.09, p < .001), perceived susceptibility (B = 0.12, p < .001), subjective norm (B = 0.05, p < .001), and perceived severity (B = -0.04, p < .001).

Conclusion

While perceived susceptibility and social norm had positive association, perceived severity had a negative association with handwashing. Considering the Korean culture, creating a shared norm for frequent handwashing could be beneficial to promote handwashing rather than emphasizing the disease and its consequences.

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

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

Factors Affecting COVID-19 Vaccination Intentions among Patients Attending a Large HIV Treatment Clinic in Trinidad Using Constructs of the Health Belief Model

Persons living with HIV are particularly vulnerable to COVID-19 and understanding the factors influencing their decision to take the COVID-19 vaccine are crucial. Using the Health Belief Model (HBM), our study examined the role of psychological factors in predicting vaccine intention in patients with HIV. The underlying concept of the HBM is that behaviour is determined by personal beliefs about a disease, and access to strategies to decrease its occurrence. A cross-sectional survey using a structured questionnaire was conducted between August and September 2021 at an HIV clinic in Trinidad. Data on the HBM constructs, namely patient's beliefs about the perceived severity and susceptibility to COVID-19, their perceived benefits of taking the vaccine, and external cues to action, i.e., factors that may motivate them to take the vaccine, were collected. Univariate and multivariable logistic regression analyses were used to examine associations and whether the HBM components were predictors of vaccination intention. In this study, 59.9% of patients indicated their intentions to take the vaccine. Females (OR 0.49, 95% CI 0.30-0.81) were less inclined to take the COVID-19 vaccine compared to males, while Indo-Trinidadian patients with HIV (OR 4.40, 95% CI 1.26-15.3) were more inclined to take the vaccine compared to Afro-Trinidadians. Health beliefs such as having confidence in the vaccine (p = 0.001) and believing in its perceived benefits (p = 0.001) were significant predictors of vaccination intention. Patients who were confident about the vaccine were six times more likely to take the vaccine (OR 6.45, 95% CI 2.13-19.5) than persons who were not confident in it. Having adequate information about the vaccine or the knowledge of others who received the vaccine (OR 1.48, 95% CI 1.03-2.11) were significant cues to action influencing their decision. Guided by the HBM, understanding patient's health beliefs is important in the design of tailored interventions to improve vaccine outcomes. The HBM may also be useful in the design of approaches to increase the uptake of critical HIV prevention, and treatment services.

Assessing the Impact of COVID-19 Phased Vaccine Eligibility on COVID-19 Vaccine Intent among African Americans in Southeastern Louisiana: A Community-Based, Cohort Study

The purpose of this study was to explore the impact of eligibility for the coronavirus 2019 (COVID-19) vaccine at the time of the vaccine rollout as a predictor of vaccine intent within the African American community.

METHODS

Four hundred eighty-seven African American participants in southeastern Louisiana were surveyed from January-April of 2021, with follow-up surveys occurring in Fall 2021. Survey domains included demographics, vaccine hesitancy, discrimination in the healthcare setting, and knowledge and experiences with COVID-19. Descriptive statistics, Chi-square tests, and binary logistic regression were performed.

RESULTS

Participants eligible for the vaccine were 1.61 times as likely to express positive vaccine intent versus ineligible participants. Additional predictors of vaccine intent were age, insurance status and coverage, and female sex at birth. In the multivariable logistic analysis, eligible individuals were 2.07 times as likely to receive the vaccine versus ineligible individuals.

CONCLUSIONS

Vaccine eligibility for the COVID-19 vaccine was a significant predictor of intent to vaccinate in the African American community. Younger individuals were less likely to have a positive intent, correlating with the eligibility of ages 16+ occurring 5 months post-vaccine approval.

Social cognitive predictors of vaccination status, uptake and mitigation behaviors in the Canadian COVID-19 Experiences survey

Emerging infectious diseases like COVID-19 will remain a concern for the foreseeable future, and determinants of vaccination and other mitigation behaviors are therefore critical to understand. Using data from the first two waves of the Canadian COVID-19 Experiences Survey (CCES; N = 1,958; 66.56 % female), we examined social cognitive predictors of vaccination status, transition to acceptance and mitigation behaviors in a population-representative sample. Findings indicated that all social cognitive variables were strong predictors of mitigation behavior performance at each wave, particularly among unvaccinated individuals. Among those who were vaccine hesitant at baseline, most social cognitive variables predicted transition to fully vaccinated status at follow-up. After controlling for demographic factors and geographic region, greater odds of transitioning from unvaccinated at CCES Wave 1 to fully vaccinated at CCES Wave 2 was predicted most strongly by a perception that one's valued peers were taking up the vaccine (e.g., dynamic norms (OR = 2.13 (CI: 1.54,2.93)), perceived effectiveness of the vaccine (OR = 3.71 (CI: 2.43,5.66)), favorable attitudes toward the vaccine (OR = 2.80 (CI: 1.99,3.95)), greater perceived severity of COVID-19 (OR = 2.02 (CI: 1.42,2.86)), and stronger behavioral intention to become vaccinated (OR = 2.99 (CI: 2.16,4.14)). As a group, social cognitive variables improved prediction of COVID-19 mitigation behaviors (masking, distancing, hand hygiene) by a factor of 5 compared to demographic factors, and improved prediction of vaccination status by a factor of nearly 20. Social cognitive processes appear to be important leverage points for health communications to encourage COVID-19 vaccination and other mitigation behaviors, particularly among initially hesitant members of the general population.

Willingness to accept a second COVID-19 vaccination booster dose among healthcare workers in Italy

Background

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is evolving,the newly emerged Omicron variant being the dominant strain worldwide, and this has raised concerns about vaccine efficacy. The purposes of this survey were to examine the extent to which healthcare workers (HCWs) intend to receive a second booster dose of the COVID-19 vaccine and the factors that influence their willingness to accept it.

Methods

The study was conducted among HCWs who were randomly selected from four public hospitals in the Campania region, Southern Italy.

Results

A total of 496 HCWs answered the questionnaire (a response rate of 61.2%). Among the respondents, 20.8% indicated a score of 10, using a 10-point Likert-type scale, regarding the usefulness of a second COVID-19 vaccine booster dose. Physicians, HCWs who believed that COVID-19 was a severe disease, and those who have acquired information about the second booster dose from scientific journals were more likely to have this positive attitude. Slightly more than half of HCWs self-reported willingness to receive a second booster dose. Respondents who believe that HCWs are at higher risk of being infected by SARS-CoV-2, those who have a higher belief that COVID-19 is a severe disease, and those who have a higher belief that a second booster dose is useful were more willing to receive a second booster dose. The main reasons for those who had a positive intention were to protect their family members and patients, whereas, the main reasons for not getting vaccinated or for uncertainty were that the dose does not offer protection against the emerging variants and the fear of its side effects. HCWs of younger age, physicians, those who have a higher belief that a second booster dose is useful, and those who were willing to receive a second booster dose were more likely to recommend the booster dose to their patients.

Conclusion

This study's findings highlight the necessity for designing and implementing educational interventions for improving second booster dose uptake and beliefs among HCWs and their capacity to recommend the vaccine to the patients.

Moral Foundations Predict COVID-19 Vaccine Hesitancy: Evidence from a National Survey of Black Americans

In this study we examine the role of moral values in predicting COVID-19 vaccine hesitancy among Black Americans. Guided by moral foundations theory, we assess the associations between six moral foundations (care, fairness, loyalty, authority, purity, liberty) and attitudes and intentions toward COVID-19 vaccination. Results of a national survey of Black Americans (N = 1,497) indicate that the care and loyalty moral foundations consistently predicted less vaccine hesitancy with overall more favorable attitudes and intentions toward COVID-19 vaccination, whereas the purity and liberty moral foundations were consistently associated with greater vaccine hesitancy. Relationships between the foundations and vaccine hesitancy were mediated by perceived vaccine effectiveness and safety. Implications of the findings for COVID-19 vaccine communication are discussed.

Factors affecting the willingness of mental health staff to get vaccinated against COVID-19

RATIONALE AND OBJECTIVE

At the beginning of vaccination against coronavirus disease 2019 (COVID-19), information about the effects of the vaccine was not known and hesitancy was observed among the population. The mental health staff members in our center in Israel had to decide whether to get vaccinated or not. The objective of this study was to evaluate the differences in demographic characteristics of vaccinated and nonvaccinated mental health care workers (HCWs), and to identify their reasons for or against vaccination.

METHOD

Data on characteristics of 357 staff members at a mental health center (MHCS) in Israel and their attitudes regarding COVID-19 vaccination, those who were nonvaccinated, were collected via anonymous questionnaires, from 1 January to 10 January 2021. The groups were then compared using χ2 , Fisher's exact tests, t test or Mann-Whitney nonparametric test as appropriate. A logistic regression was then performed using the significant variables and odd ratios presented.

RESULTS

Eighty-one per cent of the sample received at least the first dose of the vaccine. Results indicated differences in seniority (p < 0.001), profession (p < 0.001), department (p < 0.001), risk groups (p < 0.05), religion (p < 0.001), religiosity (p < 0.001), previous care for COVID-19 patients (p < 0.05) and level of interaction with patients (p < 0.01), between the vaccinated and nonvaccinated staff. The factor that was found to be most influential regarding vaccination and which convinced those originally against the vaccine to become vaccinated was the level of scientific knowledge about the vaccine.

CONCLUSION

Efforts and resources should focus on the dissemination of reliable scientific data about the vaccine, to increase vaccination rates among mental HCWs.

Characterizing intentions to receive the COVID-19 vaccine among the general population in British Columbia based on their future intentions towards the seasonal influenza vaccine

Introduction

This study assessed the relationship between intention to receive a COVID-19 vaccine and intention to receive a seasonal influenza vaccine, as well as how intention to receive a COVID-19 vaccine has changed during the pandemic.

Methods

Residents of British Columbia aged 25–69 years were invited to complete an online cross-sectional survey from August 2020 - March 2021. Mixed-effects logistic regression models assessed the relationship between intention to receive a COVID-19 vaccine and intention to receive the seasonal influenza vaccine. A generalized additive mixed model was used to investigate changes in COVID-19 vaccine intention during the pandemic (August 2020–March 2021). The relationship between intention to receive a COVID-19 vaccine and retrospective overall perceived value of vaccines prior to and during the pandemic was also considered.

Results

Of 6,333 participants, 80.2 % of participants were ‘somewhat or very likely’ to receive a COVID-19 vaccine and 69 % of participants reported intending to receive a seasonal influenza vaccine. In multivariable modeling, intention to receive a COVID-19 vaccine was strongly associated with intention to receive a seasonal influenza vaccine (aOR = 4.25, 95 %CI 3.33–5.43). Intention to receive a COVID-19 vaccine increased over the study period (p < 0.0001), with the largest increase coinciding with the announcement of forthcoming approvals of COVID-19 vaccines in November 2020 (aOR = 1.45, 95 %CI 1.11–1.91).

Conclusion

Intention to receive the COVID-19 vaccine was associated seasonal influenza vaccine intention, which is an important relationship to measure for implementation and future planning of COVID-19 booster doses. We found an increase in the intention to receive a COVID-19 vaccine after public announcements of forthcoming vaccine approval, which highlights the importance of ongoing monitoring and reporting of vaccine uptake, and the potential impact of emerging vaccine safety and efficacy information may have on vaccine acceptance.

A comparison of seasonal influenza and novel Covid-19 vaccine intentions: A cross-sectional survey of vaccine hesitant adults in England during the 2020 pandemic

We compared intention to receive the seasonal influenza vaccine with a prospective coronavirus (COVID-19) vaccine among undecided or COVID-19 vaccine hesitant individuals to better understand the underlying differences and similarities in factors associated with vaccine intention. We delivered a cross-sectional online survey in October-November 2020. We included psychological constructs and sociodemographic variables informed by theory. We conducted pairwise comparisons and multiple linear regression models to explore associations between vaccine intention and psychological constructs. We recruited 1,660 participants, where 47.6% responded that they would likely receive the influenza vaccine, 31.0% that they would probably not accept the vaccination and 21.4% were unsure. In relation to the prospective COVID-19 vaccine, 39.0% responded that they would likely receive the vaccination, 23.7% that they would probably not accept the vaccination and 37.3% were unsure. Unique factors positively associated with COVID-19 vaccine intention were: perceived knowledge sufficiency about vaccine safety, beliefs about vaccine safety, and living in an area of low deprivation. The only unique factor positively associated with influenza intention was past influenza behavior. The strongest common predictors positively associated with intention were: favorable vaccine attitudes, the anticipated regret they may feel following infection if they were not to receive a vaccine, and the expectation from family or friends to accept the vaccine. Despite overall similarities in those factors associated with vaccination intention, we identified unique influences on intention. This additional insight will help support the planning and tailoring of future immunizations programmes for the respective viruses.

Understanding Vaccine Perceptions and Willingness to Receive COVID-19 Vaccination: Opportunities to Strengthen Public Health Responses and COVID-19 Services for People Who Use Drugs

Background: People who use drugs (PWUD) are at high risk for COVID-19 infection, morbidity, and mortality. COVID-19 vaccines are safe and effective at reducing serious illness and death from COVID-19. There are sparse data on the perceptions and willingness of PWUD to receive COVID-19 vaccination. Materials and Methods: In order to assess the perceptions of, and willingness to receive, COVID-19 vaccination among PWUD, we conducted a rapid survey-based assessment of 100 PWUD in NYC (Spring 2021) who reported not having received COVID-19 vaccination and who reported past 30-day illicit drug use. Results: More than 80% of respondents agreed that personally receiving a COVID-19 vaccine was important for the health of others in the community, and endorsing this belief was significantly associated with COVID-19 vaccine willingness reflecting a high prevalence of altruistic beliefs (p-value: 0.01). Other reported perceptions that were significantly associated with COVID-19 vaccine willingness were believing that COVID-19 vaccines are safe for PWUD and trusting COVID-19 information from their healthcare providers (p-values < 0.05). That said, 62% reported being unwilling to receive a COVID-19 vaccine, and 70−83% had concerns about general vaccine safety/efficacy. Examining pairs of questions to explore potential ambivalence between vaccine endorsement and vaccine concerns identified that 56−65% simultaneously reported vaccine safety/efficacy concerns and beliefs that vaccination was an important intervention. Of the 75 respondents who reported past 30-day use of harm reduction and/or substance use disorder (SUD) programs, nearly 90% reported these programs as trusted sources of COVID-19 information. Conclusion: Most participants reported altruistic beliefs about the role of vaccines for community health, including COVID-19 vaccines, and this altruism was associated with willingness to be vaccinated against COVID-19. These findings suggest a complex relationship between beliefs about the role of vaccination in community health and the safety/efficacy of vaccines; this ambivalence suggests that COVID-19 vaccine willingness may not be firmly fixed, indicating potential opportunities to address questions and build vaccine confidence. Harm reduction and SUD programs could be leveraged to further engage PWUD in receipt of COVID-19 information and/or vaccination. Recognizing vaccine ambivalence, emphasizing collective and individual benefits of vaccination, and messaging from trusted sources may be promising approaches to increase vaccination in this population.

How Does NIMBYism Influence Residents' Behavioral Willingness to Dispose of Waste in Centralized Collection Points?-An Empirical Study of Nanjing, China

Residents' low behavioral willingness to dispose of waste in Centralized Collection Points (CCPs) seriously hinders the operational efficiency in waste collection of CCPs regarded as NIMBY ('not in my backyard') facilities. However, fewer researchers notice NIMBY facilities with low hazards. It has been ignored that the NIMBYism may influence behavioral willingness during the operation period persistently. Meanwhile, there is no consistent conclusions on internal factors of waste behavioral willingness, which deserves further study. Therefore, this study took CCPs as a research object and aimed to investigate how NIMBYism influences residents' behavioral willingness to dispose of waste in CCPs. The extended theory of planned behavior and structural equation modeling approach involving 550 respondents were adopted to conduct the analysis. The results revealed that attitude (β = 0.295, p < 0.001), government trust (β = 0.479, p < 0.001), and perceived behavioral control (β = 0.222, p < 0.001) have statistical positive impacts on behavioral willingness to dispose of waste in CCPs. Perceived risk (β = ‒0.047, p = 0.022 < 0.05) can influence behavioral willingness negatively. Additionally, government trust (β = 0.726, p < 0.001) exerts a positive impact on attitude. Furthermore, relevant strategies were proposed to enhance residents' behavioral willingness to dispose of waste in CCPs. This study is expected to inspire the government to formulate policies from the aspects of standards and regulations, resident participation, construction, and publicity. It will provide the government instructive suggestions for the smooth operation of CCPs, and ultimately building a healthy and environment friendly society.

Factors Contributing to Citizens' Participation in COVID-19 Prevention and Control in China: An Integrated Model Based on Theory of Planned Behavior, Norm Activation Model, and Political Opportunity Structure Theory

Chinese citizens' participation in COVID-19 prevention and control has made great contributions to the successful fight against the pandemic. The factors that have impacted citizens' participation have rarely been reported based on both social-psychological and political environmental theories. This paper presented a study to explore the determinants of Chinese citizens' participation in COVID-19 prevention and control based on a combined model of the theory of planned behavior, the norm activation model, and political opportunity structure theory. A dataset involving 463 respondents from Harbin in northeast China was acquired and analyzed. The results showed that the comprehensive model explained 62.9% of the total variance in citizens' participation behavior. The openness to public participation not only significantly directly influenced citizens' participation but also indirectly affected participation behaviors through attitude and perceived behavioral control, both of which were important mediators and had the greatest overall impacts. The awareness of consequences and subjective norms were crucial antecedents to the activation of other influencing factors. Personal norms indirectly affected participation behavior through the mediation of attitude. The empirical results showed the comprehensiveness, effectiveness, and high explanatory power of the postulated model. The study also provides both new theoretical perspectives for explaining public participation and useful practical implications for future policy development in promoting citizens' participation in public health emergency management.

Predicting Vaccination Intention against COVID-19 Using Theory of Planned Behavior: A Systematic Review and Meta-Analysis

This study systematically analyzed the literature using the theory of planned behavior (TPB) as a theoretical framework to examine the influence of its constructs on vaccination intention against COVID-19. Quantitative studies were searched in PubMed, CINAHL, Web of Science, and Google Scholar following the PRISMA guidelines. The average rate of COVID-19 vaccination intention was 73.19%, ranging from 31% to 88.86%. Attitude had the strongest association with vaccination intention (r₊ = 0.487, 95% CI: 0.368-0.590), followed by subjective norms (r₊ = 0.409, 95% CI: 0.300-0.507), and perceived behavioral control (r₊ = 0.286, 95% CI: 0.198-0.369). Subgroup analyses showed that the pooled effect sizes of TPB constructs on vaccination intention varied across geographic regions and study populations. Attitude had large effect sizes in Asia, Europe, and Oceania, especially among the adult general population, parents, and patients. Subjective norms had large effect sizes in Asia and Oceania, especially among parents and patients. Perceived behavioral control was the most dominant predictor of vaccination acceptance in Africa among patients. These findings suggest that TPB provides a useful framework for predicting intention to receive a COVID-19 vaccine. Hence, public awareness and educational programs aimed at promoting COVID-19 vaccination intention should consider using TPB as a framework to achieve the goal.

The role of Israeli researchers in the scientific literature regarding COVID-19 vaccines

BACKGROUND

The accurate and timely publication of scientific findings is a key component of the global response to the COVID-19 pandemic. This article explores the role of Israeli researchers in the scientific literature regarding COVID-19 vaccines.

METHODS

Content and bibliometric analysis of articles included in the Web of Science database regarding COVID-19 vaccines, that were published between January 2020 and June 2022.

RESULTS

The Web of Science includes 18,596 articles regarding COVID-19 vaccines that were published between January 2020 and June 2022. 536 (3%) of those articles had at least one Israeli author. These "Israeli articles" accounted for 11% of the NEJM articles on COVID-19 vaccines, 9% of such articles in Nature Medicine, and 4% of such articles in the Lancet. 80 of the 536 Israeli articles (15%) were recognized as "Highly Cited Papers" (articles that rank in the top 1% by citations for field and publication year). Most of the Israeli Highly Cited Papers (HCPs) analyzed the safety and/or efficacy of the COVID-19 vaccine developed by Pfizer and BioNTech (BNT162b2). Most of the Israeli HCPs made use of detailed and comprehensive individual data available from Israel's health plans, hospitals, or Ministry of Health. The 15% HCP rate (i.e., the number of HCPs divided by the number of all articles) for the Israeli articles was triple the HCP rate for all articles on COVID-19 vaccines (5%). A key factor contributing to Israel's prominent role in rapid publication of vaccination impact studies was Israel's being a world leader in the initial vaccination rollout, the administration of boosters, and the vaccination of pregnant women. Other contributing factors include Israeli researchers' access to well-developed electronic health record systems linking vaccinations and outcomes, the analytic strengths of leading Israeli researchers and research institutions, collaborations with leading research institutions in other countries, and the ability to quickly identify emerging research opportunities and mobilize accordingly. Recent developments in the priorities and selection criteria of leading journals have also played a role; these include an increased openness to well-designed observational studies and to manuscripts from outside of Europe and North America.

CONCLUSIONS

Israeli researchers, Israeli research institutions, and the Israeli government can, and should, take concrete steps to build upon lessons learned in the course of the recent surge of high-quality publications related to COVID-19 vaccines (such as the value of linking data across organizations). These lessons can be applied to a wide range of fields, including fields that go well beyond vaccines and pandemic responses.

Knowledge, attitude, acceptance, and practice of COVID-19 vaccination and associated factors complemented with constructs of health belief model among the general public in South Gondar, Ethiopia: A community-based study

Introduction

Understanding the epidemiological dynamics of disease control, as well as the effectiveness, compliance, and success of the vaccination program requires an understanding of the local population's knowledge, attitude, and practice regarding the Corona Virus Disease of 2019 (COVID-19) vaccine. Thus, the objective of this study was to assess knowledge, attitude, and practice toward COVID-19 vaccination and associated factors among the general public.

Methods

A cross-sectional study was conducted in the South Gondar Zone, among residents above the age of 18 years. The study used objective measures and the constructs of the Health Belief Model. Binary logistic regression was used and the result of the final model was presented in terms of adjusted odds ratio (AOR) and 95% confidence intervals (CI), and statistical significance was taken and considered at a P-value < 0.05.

Results

The study was conducted on 1,111 study participants. The mean age is 30.83 ± 7.106. About 575 (51.8%) of the respondents have good knowledge about the COVID-19 vaccination and 43.4% have a positive attitude toward COVID-19 vaccination. About 361 (32.5%) of the respondents were willing to take the vaccine if it is available and 113 (10.2%) of them were vaccinated. Participants with a positive attitude and good knowledge, those with a secondary level of education AOR = 5.70, 95% CI (2.60-12.60), those with a monthly income of >2,000 birr AOR = 6.30, 95% CI (2.50-15.60), those having a television (TV), and those who use Facebook AOR = 17.70, 95% CI (10.10-30.90) had a higher level of acceptance of COVID-19 vaccination. The Health Belief Model's constructs of perceived susceptibility AOR = 1.53, 95% CI (1.26-1.85), perceived benefit AOR = 1.49, 95% CI (1.28-1.75), and cues to action AOR = 0.54, 95% CI (0.45-0.65) were all linked to COVID-19 vaccine acceptability.

Conclusion

The level of acceptance of COVID-19 vaccination is much lower. Having a positive attitude score and good knowledge score, level of education, monthly income, presence of TV, the use of Facebook, and knowing the means of transmission of COVID-19 increase the level of acceptance of COVID-19 vaccination.

Count on trust: the indirect effect of trust in government on policy compliance with health behavior instructions

Trust in government is considered a prominent factor for enhancing public compliance with government policies and instructions. The Coronavirus pandemic demonstrates the crucial role public compliance with governmentally issued health guidelines has in mitigating the pandemic. However, the mechanism explaining the trust-compliance association, particularly in regard to health-behavior compliance, is unclear. This article develops a new theoretical model, the Mediated Trust Model (MTM), for explaining the relationship between trust in government and public compliance with health instructions. The model extends the classic Health Belief Model for predicting health behavior by claiming that the perceptions regarding the instructions' costs, benefits and one's ability to perform them are affected by trust in government and mediate the trust-compliance association. The MTM was tested in four cross-sectional studies performed during the first 20 months of the Coronavirus pandemic in Israel on 3732 participants, for various health instructions. Implications for public health literature, policy compliance theory and policy makers are discussed.

Factors associated with COVID-19 vaccine intention in Benin in 2021: a cross-sectional study

Introduction

The development of COVID-19 vaccines has brought considerable hope for the control of the pandemic. With a view to promoting good vaccine coverage, this study aimed to measure vaccine intention against COVID-19 and to understand the factors that promote it.

Method

In April 2021, we conducted a cross-sectional and analytical study at the national level through a telephone survey of Beninese aged 18 years or older. We used a marginal quota sampling method (n=865) according to age, gender, and department. We constructed the questionnaire using a theoretical framework of health intention. We determined the factors associated with intention to vaccinate against COVID-19 in Benin using a multinomial logistic regression at the 5% significance level.

Results

The intention to vaccinate was 64.7%; 10.9% of the population were hesitant, and 24.4% did not want to vaccinate. Thinking that it was important to get vaccinated (AOR=0.274; CI=0.118-0.638) or that getting vaccinated will help protect loved ones from the virus (AOR=0.399; CI=0.205-0.775) increased the intention to vaccinate. Having a high level of education (AOR=1.988; CI=1.134-3.484), thinking that the vaccine could put one's health at risk (AOR=2.259; CI=1.114-4.578), and hearing something negative about the vaccine (AOR=1.765; CI=1.059-2.941) reduced intention to vaccinate. In addition, believing that the creators of the vaccine had ensured its safety (AOR=0.209; CI=0.101-0.430), and believing that it was unlikely to be infected after vaccination (AOR=0.359; CI=0.183-0.703) decreased hesitancy in favour of the intention to vaccinate.

Conclusion

In April 2021, vaccine intention was high, but maintaining this high rate requires building confidence in the vaccine and combating misinformation about the vaccine.

COVID-19 Vaccine Hesitancy: Disadvantaged Groups’ Experience with Perceived Barriers, Cues to Action, and Attitudes

Purpose

Drawing from the Health Belief Model, we explored how disadvantaged groups in the U.S., including Black, Hispanic, less educated and wealthy individuals, experienced perceived barriers and cues to action in the context of the COVID-19 vaccination.

Design

A cross-sectional survey administered in March 2021.

Setting

USA

Subjects

A national sample of U.S. residents (n = 795) recruited from Prolific.

Measures

Perceived barriers (clinical, access, trust, religion/spiritual), cues to action (authorities, social circles), attitudes toward COVID-19 vaccination.

Analysis

Factor analysis and Structural Equation Model (SEM) were performed in STATA 16.

Results

Black and less educated individuals experienced higher clinical barriers (CI [.012, .33]; CI [.027, .10]), trust barriers (CI [.49, .92]; CI [.057, .16]), and religious/spiritual barriers (CI [.28, .66]; CI [.026, .11]). Hispanics experienced lower levels of clinical barriers (CI [-.42, .0001]). Clinical, trust, and religious/spiritual barriers were negatively related to attitudes toward vaccination (CI [-.45, −.15]; CI [-.79, −.51]; CI [-.43, −.13]). Black and less educated individuals experienced fewer cues to action by authority (CI [-.47, −.083]; CI [-.093, −.002]) and social ties (CI [-.75, −.33]; CI [-.18, −.080]). Lower-income individuals experienced fewer cues to action by social ties (CI [-.097, −.032]). Cues from social ties were positively associated with vaccination attitudes (CI [.065, .26]).

Conclusion

Communication should be personalized to address perceived barriers disadvantaged groups differentially experience and use sources who exert influences on these groups.

Determinants of university students' COVID-19 vaccination intentions and behavior

Vaccination hesitancy has been a major challenge for health authorities and societies during the COVID-19 pandemic. The general determinants of vaccination intentions and behavior include sociodemographic and health-related, psychological, and communication-related factors, with varying relevance for different types of vaccinations, countries, and target groups. The predictors of university students' COVID-19 vaccination behavior have not been sufficiently studied. Using a German university as an example and based on an online survey of 1398 university students, we investigated factors related to (a) the likelihood of vaccination against COVID-19 and (b) vaccination intention among those who had not been vaccinated by summer of 2021. Psychological factors showed high relevance. Field of study, trust in, and use of certain media and information channels were found to be important determinants of students' vaccination decision. Our findings can help better understand university students' vaccination behavior to develop and implement tailored strategies and campaigns.

Predictors of Influenza Vaccination among Chinese Middle School Students Based on the Health Belief Model: A Mixed-Methods Study

Influenza vaccination rates among Chinese middle school students are low. This study aims to explore the influencing factors of vaccination among middle school students and promote vaccination. We conducted a mixed-methods study, integrating a questionnaire survey among 9145 middle school students in four cities in China and semi-structured interviews with 35 middle school students to understand their attitudes and perceptions toward vaccination based on the Health Belief Model. We found the overall vaccination rate was 38.2% (3493/9145), with students in Beijing, boarding at school, or senior high school showing higher values than their counterparts (p < 0.05). Multiple logistic regression results showed that non-boarding (OR = 0.46, 95%CI: 0.42−0.51) and perceived barriers (OR = 0.97, 95%CI: 0.96−0.98) were unfavorable factors for influenza vaccination, whereas perceived susceptibility (OR = 1.07, 95%CI: 1.05−1.08), perceived benefits (OR = 1.02, 95%CI: 1.01−1.04), cues to action (OR = 1.08, 95%CI: 1.05−1.11), and self-efficacy (OR = 1.04, 95%CI: 1.02−1.07) were facilitators. Qualitative results indicated that positive health beliefs, school, and the home environment contribute to vaccination. In conclusion, the influenza vaccination rate among middle school students remains low. The concerns about the safety and potential side effects of vaccines are the main barriers to vaccination, underscoring the need for strengthening communication, education, and information among students and their teachers/parents.

COVID-19 Booster Vaccine Intention by Health Care Workers in Jakarta, Indonesia: Using the Extended Model of Health Behavior Theories

In Indonesia, COVID-19 vaccination hesitancy persists among health care workers (HCWs). Understanding the motives and challenges impacting HCWs’ acceptance of the booster vaccination is critical. Efforts are still needed to overcome apprehension about taking a booster dosage. This study aims to analyze the vaccine acceptance among HCWs in Jakarta using an extended, modified model of health behavior theories, namely The Health Belief Model (HBM) and The Theory of Planned Behavior (TPB). A cross-sectional survey from November 2021 to January 2022 was distributed to health care workers in Jakarta. Bivariate analysis followed by multivariate regression was used to assess factors associated with the vaccine intention and collected 1684 responses. The results have shown that the final model combining the constructs and demographic characteristics could explain 50% of the variance of intention to receive a COVID-19 booster vaccination. Moreover, anticipated regret had the most significant standardized coefficient among the constructs (β = 0.381, p < 0.001). Other significant predictors in the model were attitude (β = 0.243, p < 0.001), perceived benefits (β = 0.103, p < 0.001), subjective norms (β = 0.08, p = 0.005), and perceived susceptibility (β = 0.051, p = 0.016). The findings can be used to strategize interventions to increase vaccine uptake.

Knowledge and Factors Associated with Breast Cancer Self-Screening Intention among Saudi Female College Students: Utilization of the Health Belief Model

Breast cancer (BC) screening is vital, as it is linked to a greater likelihood of survival, more effective treatment, and better quality of life. One of the most extensively applied models for conceptualizing probable barriers and facilitators to the adoption of desired health behavior is the health belief model (HBM). This study aimed to assess the impact of health perception and knowledge on breast self-examination intention (BSE) using HBM. HBM measures specific factors (perceived susceptibility, severity, barriers, benefits, cues to action, and self-efficacy) that impact one's intention to use BSE. Data were collected from female undergraduate students (n = 680) using a cross-sectional design, stratified simple random sampling, and a self-administered structured online questionnaire. We used multivariable logistic regression to evaluate our assumptions for students who intended to self-examine for BC. For demographic factors, we modified the multivariate model. Most respondents (93%) were under the age of 24 years. Female students from health colleges (48.5%), in their fourth academic year (42.6%), and from the southern region (57.6%) accounted for the majority of the sample. Respondents with a family history of BC were 9.7% of the total. Categories for age, college, region, residency, and BSE intention showed significant differences in their average knowledge scores. The survey revealed that 72.4% were aware of abnormal breast changes. Three constructs of the health belief model (perceived benefit, perceived barriers, and self-efficacy) are good predictors of BSE intention. Theory-based behavioral change interventions are urgently required for students to improve their prevention practices. Furthermore, these interventions will be effective if they are designed to remove barriers to BSE intention, improve female students' self-efficacy, and enlighten them on the benefits of self-examination.

Factors Associated with COVID-19 Vaccination Acceptance Among Muslim High School Students in Jakarta Metropolitan Area, Indonesia

Purpose

This study aims to identify the factors associated with COVID-19 vaccination uptake and the intention to receive the COVID-19 vaccine among Muslim high school students in Jakarta, Indonesia.

Patients and Methods

A cross-sectional study using an online survey was conducted for high school students. The population in this study were Muslim students grade 11 and 12 at secondary high school living and studying in Jakarta Metropolitan area. A total of 440 samples have been selected using non-probability sampling. In this study, the independent variables were factors associated with vaccination behaviors that were derived from the HBM and TPB theories, while the dependent variables were vaccination uptake and vaccination intention. Factors associated with the dependent variables have been identified using chi-square and Mann-Whitney tests.

Results

About 65% respondents had received COVID-19 vaccine and 72% of those who had not received COVID-19 vaccine had the intention to receive the vaccine. Some of the behavioral model variables such as the perceived susceptibility score, perceived severity score, perceived benefits score, perceived barriers score, self-efficacy score, attitude score, and social norms score were significantly associated with COVID-19 vaccine uptake among high school students. Furthermore, all of the behavioral model variables, ie, perceived susceptibility score, perceived severity score, perceived benefits score, perceived barriers score, cues to action score, self-efficacy score, attitude score, social norms score, and perceived behavioral control score were significantly associated with an intention of being vaccinated.

Conclusion

The vaccination for students can be set in more affordable locationsfor example, in schools. In addition, efforts to increase student knowledge regarding the effectiveness and safety of vaccines and the dangers of COVID-19 should be sustained.

The impact of vaccine hesitation on the intentions to get COVID-19 vaccines: The use of the health belief model and the theory of planned behavior model

Object

During the later period of the COVID-19 pandemic, the public has been at risk of the evolving COVID-19 variants and hesitated to be vaccinated against COVID-19 to a certain extent. In this context, the health belief model (HBM) and the theory of planned behavior model (TPB) were used to compare and summarize the relationship between vaccine hesitation/non-hesitation and the intentions to get COVID-19 vaccines and its influencing factors.

Methods

The cross-sectional, population-based online survey was conducted from 14 April to 30 April 2021, and 1757 respondents were recruited to participate in the survey through the Wenjuanxing online survey platform. The HBM and TPB covariate scores were expressed using means and standard deviations and compared between groups using t-tests. Backward multiple linear regression models were used to explore the factors influencing the public's intentions to receive the COVID-19 vaccines.

Results

This study found that educational background is one of the factors influencing vaccine hesitation. Most people with high education do not hesitate (65.24%), while a more significant proportion of people with low education have vaccine hesitation (66.00%). According to HBM, for the vaccine hesitation group, self-efficacy, family advice, and doctor's advice were the most critical factors affecting the public's future vaccination intentions; for the vaccine non-hesitation group, self-efficacy, doctor's advice, and perceived benefits are the most important influencing factors. According to the TPB, the subjective norm is the most critical factor affecting the future vaccination intention of the vaccine hesitation group, and the attitude toward behavior is the most critical factor affecting the future vaccination intention of the vaccine non-hesitation group.

Conclusions

In the context of COVID-19, the public's hesitation on the "current" vaccines will still affect future vaccination intentions. Using HBM and TPB would help health policymakers and healthcare providers formulate intervention plans.

How older adults’ health beliefs affect intention to perform COVID-19 self-examination: A reasoned action approach

BACKGROUND: COVID-19 self-examination is a significant part of the national recovery plan against the virus. Although it is easier to perform COVID-19 self-examination (CSE), only a small percentage of people prefer it. There are no precise statistics on CSE in Malaysia, but informal data from news agencies imply low CSE. Lack of awareness and conflicting information about the reliability of CSE results may have raised concerns about CSE’s efficacy and effectiveness. OBJECTIVE: This study investigates how Malaysian older adults’ health beliefs influence their intention to perform CSE. The study developed a framework combining illness threats (ITH), perceived barriers (PBA), medical motivations (MMO), and control over illness (COI) from the Health Belief Model (HBM) with the Reasoned-Action Approach’s attitude (ATT), perceived control (PCO), and intention (INT). METHODS: Structural Equation Modelling (SEM) analyses were conducted with AMOS 26 software to determine the influence of HBM on older adults’ attitude, perceived control, and intention. The study collected 200 data for the pilot study and 400 data for hypotheses testing. RESULTS: ITH, MMO, and COI have positive effects, whilst PBA affects ATT negatively. ITH and COI positively impact PCO, and PCO has a greater significant effect on INT than ATT. CONCLUSION: Given the HBM’s role in influencing older adults’ intention to perform COVID-19 self-examination, providing different levels of care and emphasising the perception of knowledge of illness are especially beneficial. Several recommendations are made to ensure that CSE remains relevant for older adults’ well-being, although COVID-19’s impact has become more stabilised.

Relationship of spirituality, health engagement, health belief and attitudes toward acceptance and willingness to pay for a COVID-19 vaccine

PURPOSE

To explore the wider determinant factor of citizens' spirituality, health engagement, health belief model, and attitudes towards vaccines toward acceptance and willingness to pay for a Coronavirus disease 2019 (COVID-19) vaccination.

METHODS

A community-based cross-sectional online investigation with convenience sampling was utilized to recruit 1423 citizens from 18 districts across Indonesia between December 14, 2020 and January 17, 2021. Descriptive statistics, One-way analysis of variance, Pearson correlation, Independent t-tests, and multiple linear regression were examined.

RESULTS

Spirituality, health engagement and attitude toward vaccines, as well as health beliefs constructs (all scores of perceived benefits and barriers) were significant key factors of acceptance of vaccines. Interestingly, the spirituality, attitude toward vaccine, and health beliefs constructs including perceived susceptibility, and benefits indicated a significantly higher willingness.

CONCLUSIONS

Results demonstrated the utility of spirituality, health engagement, health belief model, and attitudes towards vaccines in understanding acceptance and willingness to pay for a vaccine. Specifically, a key obstacle to the acceptance of and willingness to pay COVID-19 vaccination included a high score of the perceived barrier construct. Moreover, the acceptance of and willingness to pay could be impaired by worries about the side-effects of a COVID-19 vaccination.

COVID-19 Vaccination Acceptance in the Context of the Health Belief Model: Comparative Cross-Sectional Study in Punjab, Pakistan

One of the models that could be used to understand the adoption of vaccine uptake is the Health Belief Model (HBM). The aim of this study is to assess the role of HBM constructs and Perceived Health Status (PHS) on the vaccination status of individuals and to understand the role of socio-demographic variables on HBM scoring. A comparative cross-sectional telephone survey was conducted among 1325 vaccinated (60.0%) and non-vaccinated (40.0%) individuals aged 40 years and above in July 2021 in Punjab province, Pakistan. A higher level of education was the strongest predictor of positive HBM. All constructs of HBM, PHS and cues-to-action were significant predictors of COVID-19 vaccination uptake, with perceived benefits as the strongest predictor. In order to expand the vaccination coverage, double-pronged interventions utilizing both information and communication technology and human resources should be designed that address each barrier perceived by individuals and understandably communicate the benefits of COVID-19 vaccination to the broader population.

Parental COVID-19 vaccination hesitancy among parents of children aged 5-18 years in Thailand: a cross-sectional survey study

BACKGROUND

To promote an acceptance rate of COVID-19 immunization among Thai children, concerns about parental vaccination hesitancy should be urgently studied. This study aimed to examine the parental COVID-19 vaccination hesitancy (PVh) level and influencing factors among Thai parents of children 5-18 years of age.

METHODS

This cross-sectional survey was conducted in Thailand during May and June of 2022. The Google forms for data collection were distributed to parents (a father, a mother, or one who nurtures and raises a child) via various online social media. Data regarding PVh level, relevant attitudes, experiences of COVID-19 and COVID-19 vaccination (EC&V), and family contexts (FC) were collected and analyzed using descriptive statistics. Mann-Whitney U test was used to compare the differences among groups of parents based on EC&V and FC. The factors influencing PVh were assessed by multiple regression analysis.

RESULTS

Four hundred and eighty-eight parents completed the online questionnaire. Their median (IQR) age was 41 (35-47) years. They lived in different provinces from all regions across Thailand. Ninety percent of them were authorized persons to make decision about children vaccination. Fifty-eight percent of the respondents had vaccine hesitancy, defined as PVh level at moderate or above. Parents who had ever refused COVID-19 vaccination for themselves or refused to vaccinate their children against any other diseases had statistically significant higher levels of PVh (p value < 0.001). Conversely, the parents who had finished the initial COVID-19 vaccine had lower PVh levels with statistical significance (p value = 0.001). Attitude towards COVID-19 (AC), attitude towards COVID-19 vaccine (AV), and perceived behavioral control (PC) of the parents negatively influenced PVh with statistical significance, according to the results of the multiple regression analysis (Betas = - 0.307, - 0.123, and - 0.232, respectively).

CONCLUSIONS

COVID-19 vaccination hesitancy was commonly found among Thai parents. The factors of the hesitancy were multifaceted. Different experiences regarding COVID-19 vaccination for themselves and any vaccinations for their children were associated with different PVhs. The attitudes especially AC, AV, and PC statistically influenced PVh. These findings should be exploited for national and local policy planning as well as public campaigns.

COVID-19 certificate as a cutting-edge issue in changing the perception of restaurants’ visitors—Illustrations from Serbian urban centers

As one of the first European cases of the introduction of COVID-19 certificates, the Serbian Government initiated the measure of limited working hours of restaurants for unvaccinated visitors. Due to such actions and frequent bans on working during the pandemic, many restaurants in Serbia had to lay off workers or close. At the end of October 2021, the certificate for entering restaurants and all catering facilities for all the visitors became mandatory. It is interesting to note that earlier findings suggested that some personality characteristics determine the specific behaviors during the pandemic, but there is still a small number of results related to restaurants’ visitors. This study aimed to investigate the predictive strength of the Big Five Factors (BFF) to attitudes toward visits to restaurants in Serbia during the pandemic, depending on the attitudes toward accepting COVID-19 certificates. A survey was conducted on a total sample of 953 visitors of restaurants in three major cities in Serbia. The results of hierarchical regression analysis showed that Openness and Extraversion positively predict attitudes toward visits to facilities during a pandemic, while Conscientiousness and Neuroticism were negative predictors. However, in the second step of hierarchical regression analysis, attitudes toward a COVID-19 certificate as a mediator variable significantly reduced the negative effect of Neuroticism on the attitudes toward visits. It seems that, by obtaining the certificate, the fear of unsafe stays in restaurants can be reduced, and that making decisions about (no) visiting restaurants during the pandemic does not necessarily have to be compromised by emotional lability.

Social asset or social liability? How partisanship moderates the relationship between social capital and Covid-19 vaccination rates across United States counties

This study investigates the interactive effect of social capital and partisanship on COVID-19 vaccination rates. Using county-level data from the United States (U.S.), we empirically find that social capital is a double-edged sword. Its effect on the vaccination rate depends on the dominant partisanship of the jurisdiction. In more liberal counties, stronger social capital is a social asset that encourages people to seek vaccination and results in a higher vaccination rate. In contrast, in more conservative counties where the Trump-voting rate reaches 73% and beyond, stronger social capital becomes a social liability for public health by reinforcing residents' hesitancy toward or rejection of vaccinations, leading to a lower vaccination rate. This study implies the need for reducing the partisanship salience and investing in bridging and linking social capital in polarized communities.

COVID-19 vaccine acceptance among pregnant women worldwide: A systematic review and meta-analysis

Background

The COVID-19 pandemic has led to the death of many people worldwide. The World Health Organization (WHO) has declared vaccine resistance as one of the greatest health threats in the world even before the COVID-19 epidemic. The aim of this study was to evaluate the acceptance of COVID-19 vaccine in pregnant women.

Method

We performed this systematic review and meta-analysis in accordance with the PRISMA guidelines. We applied the standard search strategy to the PubMed/Medline, Web of Science (ISI), Scopus, Science Direct, Cochrane Library, EMBASE, and EBSCO databases, and the Google Scholar search engine. Heterogeneity between studies was relatively high and therefore meta-analyses were performed based on random effects model with 95% CI using STATA version 16.

Results

In 16 articles with a sample size of 19219 pregnant women, the acceptance of COVID-19 vaccine was estimated 53.46% (95%CI: 47.64%-59.24%). Subgroup analysis was performed based on continent (p = 0.796), data collection method (p = 0.450) and meta-regression based on the month of the study (P<0.001), and only meta-regression was significant based on the month of the study. The effect of some variables such as graviad (OR = 1.02 [95%CI: 0.90–1.16]), maternal age was (OR = 1.02 [95%CI: 0.93–1.11]) and history of influenza vaccination (OR = 0.87 [95%CI: 0.71–1.06]) on COVID-19 vaccine acceptance was evaluated, which was not significant.

Conclusion

The prevalence of COVID-19 vaccine acceptance in pregnant women was 53.46%, which was much lower than the general COVID-19 vaccination. Therefore, necessary interventions should be taken to increase the acceptance of the vaccine, address safety concerns and educate about it.

Acceptance of COVID-19 Vaccine Booster Doses Using the Health Belief Model: A Cross-Sectional Study in Low-Middle- and High-Income Countries of the East Mediterranean Region

Coronavirus disease (COVID-19) booster doses decrease infection transmission and disease severity. This study aimed to assess the acceptance of COVID-19 vaccine booster doses in low, middle, and high-income countries of the East Mediterranean Region (EMR) and its determinants using the health belief model (HBM). In addition, we aimed to identify the causes of booster dose rejection and the main source of information about vaccination. Using the snowball and convince sampling technique, a bilingual, self-administered, anonymous questionnaire was used to collect the data from 14 EMR countries through different social media platforms. Logistic regression analysis was used to estimate the key determinants that predict vaccination acceptance among respondents. Overall, 2327 participants responded to the questionnaire. In total, 1468 received compulsory doses of vaccination. Of them, 739 (50.3%) received booster doses and 387 (26.4%) were willing to get the COVID-19 vaccine booster doses. Vaccine booster dose acceptance rates in low, middle, and high-income countries were 73.4%, 67.9%, and 83.0%, respectively (p < 0.001). Participants who reported reliance on information about the COVID-19 vaccination from the Ministry of Health websites were more willing to accept booster doses (79.3% vs. 66.6%, p < 0.001). The leading causes behind booster dose rejection were the beliefs that booster doses have no benefit (48.35%) and have severe side effects (25.6%). Determinants of booster dose acceptance were age (odds ratio (OR) = 1.02, 95% confidence interval (CI): 1.01-1.03, p = 0.002), information provided by the Ministry of Health (OR = 3.40, 95% CI: 1.79-6.49, p = 0.015), perceived susceptibility to COVID-19 infection (OR = 1.88, 95% CI: 1.21-2.93, p = 0.005), perceived severity of COVID-19 (OR = 2.08, 95% CI: 137-3.16, p = 0.001), and perceived risk of side effects (OR = 0.25, 95% CI: 0.19-0.34, p < 0.001). Booster dose acceptance in EMR is relatively high. Interventions based on HBM may provide useful directions for policymakers to enhance the population's acceptance of booster vaccination.

COVID-19 vaccine hesitancy among Israeli adults before and after vaccines' availability: A cross-sectional national survey

Vaccine hesitancy (VH) is a major health threat to the efforts to tackle COVID-19 morbidity and mortality. This study’s objectives were to assess COVID-19 VH before and after vaccines' availability and to analyze the associations between COVID-19 VH and participants’ characteristics.

A national cross-sectional telephone interview survey among Israeli adults aged 21 and older was conducted from September 2020 through May 2021. Attitudes towards COVID-19 vaccines were assessed pre/post vaccines' availability. Multivariate logistic regression analyses were used to identify associations between demographic and health-related characteristics and COVID-19 VH.

Most study participants (72.0 % of 2,998) were willing to be vaccinated against COVID-19 across the survey period. The COVID-19 VH declined significantly from 45.6 % pre-vaccine availability to 16.3 % post-vaccine availability (P < 0.001). The multivariable analysis demonstrated that post-vaccine availability, COVID-19 VH was associated with younger age, Arab ethnicity, higher level of religiosity, lower education, past diagnosis of COVID-19, and influenza VH. The main reasons for VH after the vaccine availability included insufficient data on the vaccine (37.4 %) and fear of the vaccine's side effects (33.8 %).

Despite the significant decrease in COVID-19 VH following vaccine availability, 16.3% of the population still refuses to get vaccinated. As Israel may face additional waves of the COVID-19 pandemic and booster vaccinations, multimedia vaccine promotions targeting the above-mentioned hesitant populations and their reasons for VH are urgently needed.

Willingness to pay for COVID-19 vaccines in Jordan: Applying the health belief model

BACKGROUND

To date, there is no effective treatment for COVID-19. Vaccines are effective and safe strategies to control the pandemic.

OBJECTIVE

To measure consumers' maximum willingness to pay (WTP) for COVID-19 vaccines in Jordan and to identify the predictors of WTP.

METHOD

An online survey was used to collect data related to sociodemographic factors and constructs from the Health Belief Model (HBM). The contingent valuation method using the payment card approach was used, whereby the respondents were asked to choose their maximum WTP value from a range of 5-200 Jordanian Dinar (JOD). The maximum WTP values were then categorized into several groups, and an ordered logistic model was used to generate adjusted odds ratios and estimate the significant predictors of maximum WTP.

RESULTS

A total of 3116 respondents completed the survey. More than half of the sample were not willing to pay out of pocket for the vaccine (57%). Among the respondents who were willing to pay any amount above zero, the mean maximum WTP was 28.1 JOD (39.63 USD), and the median WTP was 20 JOD (28.21 USD). The significant predictors of higher WTP values were being of younger age, higher income, being a healthcare provider, having one or more chronic diseases, previous history of receiving the seasonal influenza vaccine, having a family member/friend who has died from the COVID-19, lower perceived risk of the vaccine, higher perceived benefits of the vaccine, and having been recommended to get the vaccine.

CONCLUSION

It is recommended to continue providing the vaccine free of charge to increase its uptake. Educational campaigns should focus on refuting myths related to the vaccine and promoting the benefits of receiving the vaccine in slowing the spread of the pandemic, and improving the economy. Healthcare providers' recommendations have the potential to increase WTP for the vaccine.

Healthcare Provider Recommendations and Observed Changes in HPV Vaccination Acceptance during the COVID-19 Pandemic

Healthcare provider (HCP) recommendation of the human papillomavirus (HPV) vaccination is crucial for HPV vaccination acceptance and uptake. It is unclear to what extent the disruptive effect of the COVID-19 pandemic impacted the recommendation and acceptance of HPV vaccination. HCPs practicing in Texas were invited to complete an online survey between January and April 2021. This population-based survey examined the association between HPV vaccination recommendation by HCPs and their observed changes in HPV vaccination acceptance during the COVID-19 pandemic. Of the total 715 HCPs included in this study, 13.9% reported a decrease, 8.7% reported an increase, and 77.5% reported no change in HPV vaccination acceptance during the COVID-19 pandemic. Compared to the HCPs who never/sometimes recommend HPV vaccination, those who often/always recommend HPV vaccination were less likely to observe a decrease (12.3% vs. 22.1%) and more likely to observe an increase in HPV vaccination (9.1% vs. 6.2%), during the COVID-19 pandemic. Furthermore, those who provided recommendations often/always had 46% (odds ratio: 0.54; 95%CI: 0.30–0.96) lower odds of reporting a decrease in HPV vaccination acceptance during the COVID-19 pandemic. This study adds to prior evidence of the positive influence of provider recommendations on HPV vaccination acceptance despite the disruptive effect of the COVID-19 pandemic on cancer prevention services.

Predictors of knowledge and adherence to COVID-19 safety protocols among nurses at health facilities in Tamale Metropolis of Northern Ghana

Background

Corona Virus Disease of 2019 (COVID-19) emerged in 2019 and caused widespread disruption to many facets of life, including healthcare. Healthcare workers, particularly nurses, became the front-line fighters against the pandemic, making it imperative to comply with recommended safety protocols. However, many nurses were infected by the virus in the Tamale Metropolis, raising concerns regarding their level of adherence to the safety protocols. This study assessed the predictors of knowledge and adherence to COVID-19 safety protocols among nurses at selected health facilities in the Tamale Metropolis of northern Ghana.

Methods

A facility based cross-sectional study design was adopted and 339 nurses from six (6) public health facilities in the Tamale Metropolis were recruited for the study using questionnaires. The questionnaires were transformed into Google Forms for respondents to answer online via WhatsApp or email. The data were exported from the Google spreadsheet into SPSS and analyzed using descriptive and inferential statistics.

Results

Of the 339 participants, 60.2% were classified as having adequate knowledge while only 9.1% demonstrated high adherence to COVID-19 safety protocols. Knowledge of COVID-19 was predicted by source of information, and marital status, whereas health facility types predicted level of adherence. The odds of having adequate knowledge were higher among unmarried nurses (AOR = 1.94; 95% CI: 1.16–3.25; p = 0.012) and nurses using social media (AOR = 1.80; 95%CI 1.02–3.18; p = 0.042) compared to their counterparts. Meanwhile, primary health care nurses (AOR = 0.24; 95% CI = 0.12–0.50; p<0.001) and secondary health care nurses (AOR = 0.52; 95% CI = 0.31–0.88; P = 0.016) had reduced odds of exhibiting higher adherence compared to nurses from tertiary-level facility.

Conclusion

In this study, we found that knowledge was high but adherence to COVID-19 safety protocols was low. We suggest that facility managers should enforce compliance of their staff to the safety protocols to prevent spread of the virus within healthcare settings.

Development and implementation of an online community as a strategy for mixed methods research during a pandemic

Conducting mixed methods research is critical for healthcare researchers to understand attitudes, behaviors, and experiences on health-related topics, such as vaccine acceptance. As the COVID-19 pandemic has made it difficult to employ traditional, face-to-face qualitative methodologies, this paper describes the use of a virtual platform to conduct person-centered research. To overcome these challenges and better understand the attitudes and behaviors of vaccine-eligible individuals in the United States, an online health community called the Virtual Engagement Research Community (VERC) was designed and implemented. Using the Health Belief Model as a framework, the VERC employed a mixed methods approach to elicit insights, which included discussion topics, rapid polls, and surveys. Throughout the initial enrollment period of April-October 2021, continuous improvement efforts were made to bolster recruitment and member engagement. This agile research strategy was successful in utilizing mixed methods to capture community sentiments regarding vaccines. While this community focused on vaccination, the methodology holds promise for other areas of health research such as obesity, HIV, mental health disorders, and diabetes.

Temporal Trend of COVID-19 Vaccine Acceptance and Factors Influencing International Travellers

The COVID-19 pandemic has seen disrupted international travel due to travel restrictions and public health measures aimed at containing the spread of the virus. With increasing evidence of the COVID-19 vaccines' ability to mitigate disease severity, reopening tourism is desirable to promote the recovery of the global economy. However, the COVID-19 vaccine and vaccination passport for international travellers remains an ongoing debate. Little is known of the acceptance of these and the influencing factors among this population group. Therefore, this study sought to determine the temporal trend in COVID-19 vaccine acceptance and influencing factors among international travellers. A cross-sectional study was conducted using a self-administered questionnaire among international travellers who visited the Thai Travel Clinic, Hospital for Tropical Diseases, Mahidol University, Thailand from June 2021 to December 2021 (3 different variants dominated during this period). Study data were analyzed using SPSS software, version 23. Chi-square was used to demonstrate associations. Binary logistic regression was used to evaluate the magnitude of effect, demonstrated by odds ratio with 95% confidence interval. All significant variables were included in a multinomial logistic regression model to estimate adjusted odds ratios. The study enrolled 1068 travellers, 719 (67.3%) Thai and 349 (32.7%) foreign travellers. Most travellers were female (55.4%) and aged 18-30 years. The three main purposes for visiting the clinic were: for study, visiting friends and relatives, and returning to their home country. The overall COVID-19 vaccine acceptance rate among the travellers was 96.2%. The temporal trend of acceptance among Thai and non-Thai travelers varied from 93-99% and 93-100%, respectively. Vaccine efficacy, protective duration of the vaccine, risk of infection, and travel plan were factors strongly associated with COVID-19 vaccine acceptance. In conclusion, the COVID-19 vaccine acceptance rate among these international travellers was very high. The safe and effective reopening of tourism to international travellers will facilitate economic recovery.

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.

Factors associated with intention to take COVID-19 vaccine among the university students in Bangladesh

Purpose

This study examined the Bangladeshi university students' intention to take coronavirus disease 2019 (COVID-19) vaccines by assessing the Health Belief Model and Theory of Planned Behavior.

Materials and Methods

University students were queried on their intention to take COVID-19 vaccines. The sample used in this study (n=310) was obtained through an online survey among university students (age, 18-25 years old) from August 7 to September 18, 2021.

Results

Although over 90% of respondents showed their willingness to take the COVID-19 vaccine, around 37.3% of respondents still desired to wait and see to take the vaccine. The most frequently cited reasons for vaccines hesitancy were concerns over side effects (62.4%). There is still an unmet need for adequate information on COVID-19 vaccines (81.4%). Results of the binary logistic regression model showed that students from private universities (odds ratio [OR], 0.19; 95% confidence interval [CI], 0.04-0.97), respondents who concerned about the vaccine safety (OR, 0.07; 95% CI, 0.01-0.44) and side effects of vaccine (OR, 0.21; 95% CI, 0.05-0.89) were less willing to take COVID-19 vaccine. On the other hand, desire to wait to take COVID-19 vaccines was associated with marital status (OR, 7.76; 95% CI, 1.50-40.27); COVID-19 preventive behavior, including use of facemask (OR, 0.25; 95% CI, 0.09-0.70) and maintain social distance (OR,1.75; 95% CI, 1.00-3.07); COVID-19 infection (OR, 0.50; 95% CI, 0.26-0.99); provide more information on vaccines (OR, 2.32; 95% CI, 1.06-5.09); the perceived side effects (OR, 2.82; 95% CI, 1.54-5.17); and effectiveness of COVID-19 vaccines (OR, 2.41; 95% CI, 1.16-5.01).

Conclusion

Public health managers should provide adequate information on COVID-19 vaccines to address the concerns about the safety and side effects of the vaccines.

COVID-19 Vaccine Hesitancy among Parents of Children under Five Years in the United States

On 17 June 2022, the U.S. FDA authorized the Pfizer-BioNTech and Moderna COVID-19 (SARS-CoV-2) vaccines for emergency use (EUA) in children ages 6 months–4 years. Seroprevalence has increased during the current Omicron variant wave for children under 5 years, and the burden of hospitalization for this age group is similar or exceeds other pediatric vaccine-preventable diseases. Research following the October 2021 EUA for vaccines for children 5–11 indicates a high prevalence of parental vaccine hesitancy and low uptake, underscoring the urgency of understanding attitudes and beliefs driving parental COVID-19 vaccine rejection and acceptance for younger children. One month prior to FDA approval, in the present study 411 U.S. female guardians of children 1–4 years from diverse racial/ethnic, economic, and geographic backgrounds participated in a mixed method online survey assessing determinants of COVID-19 pediatric vaccine hesitancy. Only 31.3% of parents intended to vaccinate their child, 22.6% were unsure, and 46.2% intended not to vaccinate. Logistic regression indicated significant barriers to vaccination uptake including concerns about immediate and long-term vaccination side effects for young children, the rushed nature of FDA approval and distrust in government and pharmaceutical companies, lack of community and family support for pediatric vaccination, conflicting media messaging, and lower socioeconomic status. Vaccine-resistant and unsure parents were also more likely to believe that children were not susceptible to infection and that the vaccine no longer worked against new variants. Findings underscore the need for improved public health messaging and transparency regarding vaccine development and approval, the importance of community outreach, and increased pediatrician attention to parental concerns to better improve COVID-19 vaccine uptake for young children.

Higher Collective Responsibility, Higher COVID-19 Vaccine Uptake, and Interaction with Vaccine Attitude: Results from Propensity Score Matching

Providing both personal and social benefits, vaccination may be motivated by collective responsibility (CR). Some previous studies have indicated the relationship between CR and vaccination but could not exclude confounding bias and had little knowledge about the boundary conditions. This study aimed to examine the association between CR and COVID-19 vaccine uptake and its boundary conditions in an extended version of the theory of planned behavior. A cross-sectional survey with 608 participants from six tourism satellite industries in Macao was conducted from 28 July 2021 to 20 August of 2021. Respondentss in CR-lower and CR-higher groups were 1:1 paired using propensity score matching (PSM) to control the potential confounding factors. Results showed participants in the CR-higher group reported significantly higher COVID-19 vaccine uptake than those in the CR-lower group (64.7% vs. 49.7%, p = 0.005). Multivariate logistic regression results indicated a positive association between CR and COVID-19 vaccine uptake (p = 0.012, OR = 2.070, 95% CI= 1.174 to 3.650) and its interaction effect with COVID-19 vaccine attitude (p = 0.019, OR = 0.922, 95% CI = 0.861 to 0.987). Spotlight analysis further illustrated that CR was more effective among individuals with a more negative COVID-19 vaccine attitude. These findings may help promote understanding of vaccine hesitancy, and hence optimize vaccination communication strategies during the COVID-19 pandemic.

Factors influencing physician's behavioral intention to use Traditional Chinese Medicine to treat coronavirus disease 2019 based on the theory of planned behavior

OBJECTIVE

To explore the factors influencing physicians' intentions to use Traditional Chinese Medicine (TCM) to treat coronavirus disease 2019 (COVID-19).

METHODS

A cross-sectional, self-report online survey was conducted from March 16, 2020, to April 2, 2020, in China. Participants were recruited through convenience and snowball sampling. Data were collected by using a self-designed questionnaire based on the Theory of Planned Behavior. Structural equation modeling was used for data analysis.

RESULTS

A total of 494 physicians were enrolled in this study. Overall, the model explained 75.4% and 75.5% of the total variance in intention and attitude, respectively. Specifically, attitudes (β = 0.467, P < 0.001), past behavior (β = 0.384, P < 0.05), subjective norms (SN) (β = 0.177, P < 0.001), and perceived behavioral control (PBC) (β = 0.133, P < 0.05) significantly affected physicians' intention to use TCM. Cognition (β = 0.606, P < 0.001) and PBC (β = 0.569, P < 0.01) significantly influenced physicians' attitudes toward using TCM. SN (β = 0.064, P = 0.263) was not a factor affecting attitude.

CONCLUSION

Physicians' intention to use TCM was significantly associated with attitude, past behavior, PBC, and SN. The findings may not only be useful for understanding the influencing factors and paths of physicians' intention to use TCM to treat COVID-19 but also provide a reference for health authorities and policymakers to promote physicians to utilize TCM.

Personal and contextual determinants of COVID-19 vaccination intention: a vignette study

BACKGROUND

This vignette study explores which factors contribute to higher COVID-19 vaccination intentions.

METHODS

Between the 4^th-11 January 2021, we recruited 15,901 Belgian citizens (M_age = 50.11 years, range 18-100) through convenience sampling to participate in a vignette study. In each vignette, we manipulated contextual determinants consisting of different factors. Each participant rated six vignettes in terms of the outcomes 'vaccination intention' and 'recommendation to others.' Finally, we explored the benefits of tailored communication by examining whether these ratings depended upon citizens' initial motives for vaccination.

RESULTS

Participants are most likely to accept a vaccine when they expect no or only small side effects, when the vaccine offers a 95% protection, and when people can no longer infect others (p < 0.001). The possibility to receive the vaccine at home or at the GP's office, highlighting that most citizens are willing to get vaccinated, and emphasizing the protective benefits for others yielded additional positive effects (p < 0.001). Results showed that tailored communication has a small but significant effect, especially for individuals high on distrust-based amotivation (p < 0.01).

CONCLUSION

In addition to vaccine characteristics, there is room for policymakers to respond to those determinants that fall under their control and can thus be highlighted within communication campaigns.
