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 5397 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.
