However, identifying community apprehensions towards vaccination needs to be understood in detail. This study aims to determine the factors that can predict the acceptance of the COVID-19 vaccine.Methods: A cross-sectional study was considered by systematic random sampling of 425 adults with chronic illnesses in Ho Chi Minh City. Data were collected between December 2020 and January 2021 via a self-administered, structured questionnaire. The main outcome was the acceptance of future COVID-19 vaccinations.Results: A total of 425 eligible adults responded to the survey, whose mean age was 52.9± 15.6 years; 67.8% of them were women, more than a half of them had high school education level or higher (57.4%) and received COVID-19 information mainly via television and social media accounted for 82.4% and 58.1%, respectively. Overall, knowledge of COVID-19 was reported as relatively good, with a mean score of 7.11 ± 1.77 (0– 9). Determinants of vaccination acceptance were knowledge and cues to action. Accordingly, there was a 1.2-fold increase in the odds of acceptance of COVID-19 vaccination for a 1-unit increase in “the total knowledge score” (AOR 1.2, 95% CI: 1.1– 1.3, p< 0.05), and there was a 3.2-fold increase in the odds of vaccination acceptance for a 1-unit increase in “cues to action” (AOR 3.2, 95% CI: 1.7– 5.8, p< 0.001).Conclusion: Determinants that influence the intention to have the COVID-19 vaccination are identified, which can be applied to future health education interventions that should focus on enhanced knowledge towards COVID-19 via mass media messages and cues to action from healthcare workers’ recommendations to promote vaccine acceptance.Keywords: beliefs, COVID-19, health belief model, knowledge, vaccination |
