Prevalence and factors associated with belief in COVID-19 vaccine efficacy in Indonesia: A cross-sectional study

Abstract

Objective: To investigate the prevalence of belief in COVID-19 vaccine efficacy and its associated factors. Methods: Due to mobility restriction, this study was conducted cross-sectionally via online platforms. The included factors were age, gender, religious identity, marital status, education level, occupation, and living with health workers. Logistic regression was used to assess the association between belief in COVID-19 vaccine with the predictors. Results: A total of 5 397 responses were taken into analysis. The prevalence of belief in COVID-19 vaccine efficacy was 62.3%. Whereas factors associated with belief in COVID-19 vaccines were being in the age of 45-54 (aOR 1.767; 95% CI 1.219-2.562), 55-64 (aOR 1.703; 95% CI 1.219-2.562), and >64 (aOR 2.136; 95% CI 1.128-4.047), completing education until the secondary level (aOR 1.354; 95% CI 1.111-1.650), working as health practitioners (aOR 2,353; 95% CI 1.655-3.344), and living with health workers (aOR 1.278, 95% CI 1.079-1.514). All religious identities including Muslim (aOR 2.447; 95% CI 1.183-5.062), Protestant (aOR 3.615; 95% CI 1.703-7.677), Catholic (aOR 4.486; 95% CI 2.015-9.987), and Hindu (aOR 3.286; 95% CI 1.410-7.655) showed significant association with belief in COVID-19 vaccine efficacy. Conclusions: A high prevalence of belief in COVID-19 vaccine efficacy was evident. Since vaccine compliance is determined by an individual's risk-benefit perception, this study emphasizes the need of raising awareness of the benefits of COVID-19 immunization.
