Nevertheless, some peopleare reluctant to be vaccinated because of potential side effects. This study aimed to analyze the effects of knowledge,attitudes, and behavior related to the coronavirus disease 2019 (COVID-19) vaccine acceptance.Material and Methods: This is a quantitative study that employed the cross-sectional approach and was conducted from December 2021 to February 2022. Data were collected from 520 samples aged 22-64 years chosen via simple random sampling. The data collection was carried out using a questionnaire via Google Forms. To analyze the acceptance of the COVID-19 vaccination program in the community, multiple linear regressions using the SPSS software version 25 were employed.Results: Knowledge (b=0.11, SE=0.05, 95% CI=0.01 to 0.21, p-value=0.030), attitude (b=0.08, SE=0.03, 95% CI=0.03 to 0.13, p-value=0.003), and behavior (b=0.07, SE=0.02, 95% CI=0.03 to 0.10, p-value<0.001) affected the COVID-19 vaccine acceptance. The higher the knowledge about the COVID-19 vaccine, the higher the public acceptance of the vaccination program. Likewise, the more positive the public’s attitude towards the COVID-19 vaccine, the higher its acceptance of the vaccination. The better the public’s behavior related to COVID-19 vaccination, the higher the level of acceptance of the COVID-19 vaccine.Conclusion: Comprehensive knowledge, positive attitudes, and good behavior related to the COVID-19 vaccinationaffect the acceptance of COVID-19 vaccine by the public of Indonesia.
