The Relationship between Depression and COVID-19 Vaccine Uptake and Intention among Korean Adults: The 2021 Community Health Survey

Abstract

Individuals with depressive symptoms are vulnerable to COVID-19 infection and mortality; therefore, their vaccination status must be investigated to reduce these rates. This study investigated the association between depressive symptoms and COVID-19 vaccine uptake and intention and identified the reasons for vaccine avoidance. Data were collected from the 2021 Korea Community Health Survey and analyzed using logistic regression. A statistically significant association was found between the presence of depressive symptoms and no COVID-19 vaccine uptake. Among individuals who reported experiencing depression, 4.6% were unvaccinated and 7.7% reported no intention to get vaccinated. Among the unvaccinated, the adjusted odds ratio (aOR) for depression was 1.53 (95% confidence interval: 1.45–1.61) compared to the vaccinated. Similarly, a significant association was observed between depressive symptoms and no intention to get vaccinated. In the group with no vaccine intention, the aOR for depression was 2.06 (95% CI: 1.86–2.27) compared to the group with vaccine intention. Furthermore, “health-related reasons” and “concerns about side effects or past experience of side effects” accounted for 89% of the reasons for vaccine avoidance among individuals with depression. Therefore, it is important to provide tailored information and develop programs to increase awareness and promote COVID-19 vaccine uptake among these individuals.
