Intention to receive COVID-19 vaccine and its health belief model (HBM)-based predictors: A systematic review and meta-analysis

The purpose of the research was to pool the intention to receive the COVID-19 vaccine and its health belief model (HBM)-based predictors, which is helpful for decision-makers and program managers around the globe. The relevant database was searched and Joanna Briggs Institute (JBI) appraisal checklist was used to evaluate the studies. I2 test and funnel plot was utilized to check heterogeneity and publication bias, respectively. DerSimonian and Laird random-effects model was used. The overall pooled intention to receive COVID-19 vaccine globally was 67.69%. Higher levels of perceived susceptibility (AOR = 1.85), perceived severity (AOR = 1.45), perceived benefits (AOR = 3.10), and cues to action (AOR = 3.40) positively predicted the intention; whereas high level of perceived barrier negatively predicted it (AOR = 0.53). Health beliefs influenced COVID-19 vaccine intention globally. This implies that individuals need sound health education and publicity about vaccines before vaccination.
