Acceptance of a Third Dose of COVID-19 Vaccine and Associated Factors in China Based on Health Belief Model: A National Cross-Sectional Study

COVID-19 infections are returning to many countries because of the emergence of variants or declining antibody levels provided by vaccines. An additional dose of vaccination is recommended to be a considerable supplementary intervention. We aim to explore public acceptance of the third dose of the COVID-19 vaccine and related influencing factors in China. This nationwide cross-sectional study was conducted in the general population among 31 provinces in November, 2021. We collected information on basic characteristics, vaccination knowledge and attitudes, and vaccine-related health beliefs of the participants. Univariable and multivariable logistic regression models were used to assess factors associated with the acceptance of a third COVID-19 vaccine. A total of 93.7% (95% CI: 92.9–94.6%) of 3119 Chinese residents were willing to receive a third dose of the COVID-19 vaccine. Individuals with low level of perceived susceptibility, perceived benefit, cues to action cues, and high level of perceived barriers, old age, low educational level, low monthly household income, and low knowledge score on COVID-19 were less likely to have the acceptance of a third dose of COVID-19 (all p < 0.05). In the multivariable logistic regression model, acceptance of the third dose of COVID-19 vaccine was mainly related to previous vaccination history [Sinopharm BBIP (aOR = 6.55, 95% CI 3.30–12.98), Sinovac (aOR = 5.22, 95% CI:2.72–10.02), Convidecia (aOR = 5.80, 95% CI: 2.04–16.48)], high level of perceived susceptibility (aOR = 2.48, 95% CI: 1.48–4.31) and high level of action cues (aOR = 23.66, 95% CI: 9.97–56.23). Overall, residents in China showed a high willingness to accept the third dose of COVID-19 vaccines, which can help vaccine manufacturers in China to manage the vaccine production and distribution for the huge domestic and international vaccine demand. Relevant institutions could increase people’s willingness to booster shots by increasing initial COVID-19 vaccination rates, public’s perception of COVID-19 susceptibility and cues to action through various strategies and channels. Meanwhile, it also has certain reference significance for other countries to formulate vaccine promotion strategies.

Factors Influencing Protective Behaviors for Dental Radiation Exposure among Female Korean Dental Hygienists Using Health Belief Model

This study aimed to identify the associated factors for protective behaviors for dental radiation exposure (PBDRE) among dental hygienists using the health belief model (HBM). The HBM, which is composed of perceived susceptibility, perceived seriousness, perceived benefits, perceived barriers, and cues to action, explains preventive behavior. In this study, self-efficacy and modifying factors were additionally applied to the HBM. The subjects of the study were 204 dental hygienists who were working at hospitals or clinics in Korea. An online survey was conducted to measure PBDRE-related factors based on the HBM and self-efficacy. The collected data were analyzed using frequency analysis, t-tests, ANOVA, Pearson’s correlation analysis, and hierarchical multiple regression analysis. Regarding modifying factors, performance was found to be high when protection facilities were sufficient (β = 0.24, p < 0.001) and low when radiation education was not received (β = −0.16, p < 0.05). Among the HBM factors, cues to action for PBDRE (β = 0.28, p < 0.001) was the most influential factor in the performance of PBDRE, and the effect of its perceived benefits on radiation exposure was also high (β = 0.17, p < 0.001). Regarding the performance of PBDRE according to the HBM, providing education programs on protection can stimulate appropriate cues to action to perform PBDRE. In addition, if the benefits of PBDRE are highlighted, the performance of PBDRE by dental hygienists is increased.

Analysis of wearing masks compliance during the COVID-19 pandemic based on the Health Belief Model

Background: Maintaining physical distance, washing hands, and wearing masks during the COVID-19 pandemic are very important in preventing the spread of the virus. However, although the use of facemasks is relatively easy to do, its compliance is considered low.Objective: This study aimed to analyze compliance in wearing masks during the COVID-19 pandemic.Methods: This cross-sectional study was conducted on 400 residents in Palembang, Indonesia, selected using simple random sampling from August to September 2021. Data were collected using online questionnaires and analyzed using descriptive statistics, Chi-square, and multivariate using logistic regression.Results: The findings revealed that sex, education, and employment status were significant relationships to compliance to wearing masks (p0.05), but age and family income were not significantly related (p0.05). Multivariate analysis showed only perceived severity and cues to action had a significant relationship with compliance to wearing masks after it was controlled by the sex variable (p0.05), with PR of 0.558 (95% CI 0.331-0.941) and 0.410 (95% CI 0.242-0.696), consecutively.Conclusion: Perceived severity and cues to action are factors that influence compliance to wearing masks. Therefore, these two factors should be considered by public health practitioners as well as the government to increase the compliance wearing masks.

Parents intention to vaccinate their 5-11 years old children with the COVID-19: vaccine rates, predictors and the role of incentives

Background: On September 20, 2021, Pfizer announced encouraging effectiveness and safety results from their COVID-19 vaccine clinical trials in 5-11 years old children. This study aims to assess parents perceptions and intention to vaccinate their 5-11 years old children and to determine the socio-demographic, health-related and behavioral factors, as well as the role of incentives beyond these factors, in predicting this intention. Methods: A cross-sectional representative online survey among parents of children aged 5-11 years in Israel (n=1,012). The survey was carried out between September 23 and October 4, 2021, at a critical time, immediately after Pfizers announcement. Two multivariate regressions were performed to determine predictors of parents intention to vaccinate their 5-11 years old children against COVID-19 in the coming winter and how soon they intend to do so. Results: Overall, 57% of the participants reported their intention to vaccinate their 5-11 years old children against COVID-19 in the coming winter. This intention was higher for participants over the age of 40. Perceived susceptibility, perceived benefits, perceived barriers, and cues to action, as well as two incentives - vaccine availability and receiving a green pass - were all significant predictors of this intention. When asked about how soon they intend to vaccinate their 5-11 years old children, 27% of the participants responded immediately; 26% within three months; and 24% within more than three months. Participants having a family member suffering from a chronic disease as well as those whose children were vaccinated against influenza in the previous winter intend to vaccinate their children sooner. Perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and cues to action, were all found to be significant predictors of this sense of urgency. Similar to the intention to vaccinate children in the coming winter, while vaccine availability and receiving a green pass were found to be positive significant predictors of how soon parents intend to vaccinate their children, other incentives such as monetary rewards or monetary penalties were not found to be significant predictors. Parental concerns centered around the safety of the vaccine (64%), fear of severe side effects (60%), and fear that clinical trials and the authorization process were carried out too quickly (56%). Conclusions: This study provides up-to-date information on the rates of the intention of parents to vaccinate their 5-11 years old children, how soon they intend to do so, and the predictors of those intentions, which is essential for health policy makers and healthcare providers for planning vaccination campaigns. Moreover, as vaccine safety and side effects were found to be key parental concerns, it is important to release post-approval safety data regarding the vaccine to the public as soon as such is available. Finally, our findings underscore the important role of vaccine accessibility and receiving a green pass over other incentives in promoting parents intentions to vaccinate their children.

Factors related to preventive COVID-19 behaviors using health belief model among general population: a cross-sectional study in Iran

Background Coronavirus disease (COVID-19) pandemic has become one of the biggest challenges to global health and economy. The present study aimed to explore the factors related to preventive health behaviors during the COVID-19 pandemic in Khuzestan Province, South of Iran, using the Health Belief Model (HBM). Methods The present cross-sectional study was conducted in the period between July 2020 and September 2020. A total of 1090 people from Khuzestan province participated in the study. The data collection method included a multistage cluster sampling method with a random selection of provincial of health centers. The questionnaire collected socio-demographic information and HBM constructs (e.g., perceived susceptibility, perceived severity, perceived benefits and barriers, cues to action, and COVID-19 preventive behaviors). Data were analyzed using ANOVA, t-test, hierarchical multiple linear regression, and SPSS version 22. Results The mean age of the participants was 35.53 ± 11.53, more than half of them were female (61.6%) and married (65.3). The results showed that 27% of the variance in the COVID-19 preventive behaviors was explained by HBM constructs. The regression analysis indicated that female gender (β = 0.11), perceived benefits (β = 0.10), perceived barriers (β = − 0.18), external cues to action (β = 0.25), and internal cues to action (β = 0.12) were significantly associated with COVID-19 preventive behaviors (p < 0.05). Conclusion Designing an educational intervention on the basis of HBM might be considered as a framework for the correction of beliefs and adherence to COVID-19 behavior. Health information campaigns need to (1) emphasize the benefits of preventive behaviors including avoiding the likelihood of getting a chronic disease and complications of the disease, (2) highlight the tips and advice to overcome the barriers (3) provide cues to action by means of showing various reminders in social media (4) focusing on adoption of COVID-19-related preventive behaviors, especially among men.

Predictors of COVID-19 Vaccine Acceptability Among Health Professions Students in Vietnam

Background: The COVID-19 vaccine hesitancy or refusal has actually been a threat to global health. In the current situation, health profession students are at risk for SARS-CoV-2 infection during their internship at healthcare facilities. Furthermore, those future healthcare workers will advise people to accept the COVID-19 vaccination. Therefore, the attitude of students towards vaccine acceptance and the predicting factors needs to be elucidated. This study applied the Health Belief Model to determine predictors of COVID-19 vaccine acceptability among health professions students. Methods: 911 students participated in a cross‐sectional online survey in Vietnam. Multinomial logistic regression model determined predictors of the COVID-19 vaccine acceptability. Results: The overall vaccine acceptance, hesitancy, and refusal rates were 58% (95% CI: 54.7% - 61.3%), 40.4% (95% CI: 37.2% - 43.7%) and 1.5% (95% CI: 0.8% - 2.6%), respectively. Regarding vaccination hesitancy, a predictor such as "Receiving recent flu shots” had a negative correlation, whereas "Vaccines haves little efficacy & serious adverse effects” (Perceived barriers), nationality, and majors were positive correlates. For refusal, "Unvaccinated students feasibly infected COVID-19 during hospital internship” (Perceived susceptibility) was a negative correlate. For both hesitancy and refusal, "Mass media appreciating effectiveness and safety of vaccines" (Cues to action), and " Health professions students get serious complications of COVID-19 if not vaccinated" (Perceived severity) had a negative correlation. In contrast, "Manufacturers do not disclose adverse effects of vaccines" (Cues to action), and "Adverse effect causes death" (Perceived barrier) were positive correlates. Strong Health Belief Model predictors of vaccine refusal were "Manufacturers do not disclose adverse effects of vaccines" (Cues to action) (OR= 5.299, 95% CI: 1.687-16.641, p= 0.004), and "Adverse effect causes death" (Perceived barrier) (OR= 10.255, 95% CI = 3.528-29.814, p= 0.0005). Conclusion: Perceived susceptibility to and severity of COVID-19 might lead to vaccination acceptance among students. However, concerns of vaccine effectiveness and safety may still affect the choice of refusal or hesitancy in vaccination. Health information from mass media and transparency of vaccine effectiveness and safety could improve COVID-19 vaccine acceptance.
