Factors influencing knowledge, attitude, and behavior on COVID-19 vaccination program in Indonesia

Background: Vaccination has been one of the globally used efforts to minimize the spread of COVID-19 disease, including in Indonesia. The rising number of false rumours has been a challenge for the COVID-19 booster vaccination program in Indonesia. From this perspective, it is important for the community to have adequate knowledge and a positive attitude toward the COVID-19 vaccine. This study aimed to analyse the factors that influence the community’s knowledge, attitude, and behaviour toward the COVID-19 vaccination program among Indonesians. Methods: This is a cross-sectional study using an online survey form distributed through social media using a snowball sampling method, responded by 595 participants during the period between June and August 2021. The survey assessed factors that influence Indonesian adults’ knowledge about COVID-19 and factors that influence their attitude toward COVID-19 vaccination. Results: A total of 576 out of 595 filled-in questionnaires were eligible for analysis. Among respondents, 85.4% already received mandatory vaccination programs in their childhood, and almost half of them also received additional non-mandatory vaccine programs. Almost all of the respondents expressed a positive attitude toward the COVID-19 vaccination program. Conclusions: The Indonesian community in general had adequate knowledge and a positive attitude towards COVID-19 vaccination. Those factors significantly influenced the attitude and affected their behaviour toward acceptance of the COVID-19 vaccination and its future vaccination booster program.
