Based on the expanded health belief model, this study analyzed the factors influencing individuals' intention to receive the COVID-19 vaccination. Specifically, perceived severity and vulnerability to COVID-19, perceived benefits and barriers regarding COVID-19 vaccination, social norms (prescriptive norms, descriptive norms), self-efficacy, individual emotions, and partisan media use were examined as the influencing factors on vaccination intention against COVID-19. An online survey was conducted with 525 Seoul citizens who had no confirmed COVID-19 experience in February, 2022. As a result, it was found that the higher the perceived severity of COVID-19, the perceived benefits, social norms and self-efficacy regarding COVID-19 vaccination, the higher the intention to get COVID-19 vaccination in near future. On the other hand, it was found that the higher the perceived benefits of COVID-19 vaccine and anger toward the COVID-19 vaccination, the lower the intention to get the COVID-19 vaccination. In addition, it was found that the respondents who used more conservative media had lower intentions to get the vaccination against COVID-19. The theoretical and practical implications of the main findings were discussed.
