Description
Summary:	In Indonesia, COVID-19 vaccination hesitancy persists among health care workers (HCWs). Understanding the motives and challenges impacting HCWs' acceptance of the booster vaccination is critical. Efforts are still needed to overcome apprehension about taking a booster dosage. This study aims to analyze the vaccine acceptance among HCWs in Jakarta using an extended, modified model of health behavior theories, namely The Health Belief Model (HBM) and The Theory of Planned Behavior (TPB). A cross-sectional survey from November 2021 to January 2022 was distributed to health care workers in Jakarta. Bivariate analysis followed by multivariate regression was used to assess factors associated with the vaccine intention and collected 1684 responses. The results have shown that the final model combining the constructs and demographic characteristics could explain 50% of the variance of intention to receive a COVID-19 booster vaccination. Moreover, anticipated regret had the most significant standardized coefficient among the constructs (beta = 0.381, p < 0.001). Other significant predictors in the model were attitude (beta = 0.243, p < 0.001), perceived benefits (beta = 0.103, p < 0.001), subjective norms (beta = 0.08, p = 0.005), and perceived susceptibility (beta = 0.051, p = 0.016). The findings can be used to strategize interventions to increase vaccine uptake.
