COVID-19 Vaccine Intention Among Iranian Health Workers: Application of the HBM Model

The study aimed to determine the application of the health belief model (HBM) in the acceptance of COVID-19 vaccination among health workers in 2021. The cross-sectional study was conducted on 3600 health workers from February to March 2021. Data was collected using a researcher-made questionnaire that included the intention to receive vaccines based on the health belief model constructs. Data were analyzed using descriptive statistics indicators, Chi-square, ANOVA test, and logistic regression model at a 95% confidence level. More than 62% of the participants intended to receive the vaccine. The odds of intention to receive the vaccine among people who worked in the health center and did not have a history of hospitalization due to COVID-19 disease were 1.50 and 2.10 units more than the others. Intention to receive the vaccine in individuals with high perceived sensitivity was 1.10 units. Furthermore, in terms of perceived benefits, self-efficacy, and cue-to-action constructs were 1.15, 1.34, and 1.65 units respectively. The rate of vaccine acceptance among Iranian health care workers was relatively good and the constructs of HBM in predicting the rate of intention to receive the vaccine had good applicability.
