Uptake of COVID-19 Vaccination and Its Associated Factors among College Students in China: A Nationwide Cross-Sectional Study

Our study aims to assess the uptake of COVID-19 vaccination and its associated factors among Chinese college students. A web-based cross-sectional study was conducted from 18 May to 17 June 2022. A total of 3916 participants were included. The coverage of the first dose, complete vaccination and booster vaccination among college students was 99.49%, 81.96% and 79.25%, respectively. College students with an older age (AOR: 0.72, 95% CI: 0.57–0.90), non-medical major (0.47, 0.37–0.61) and studying in north-east China (0.35, 0.22–0.58) were less likely to complete vaccination. Individuals who were female (1.62, 1.35–1.94) and received a recombinant subunit vaccine (8.05, 5.21–12.45) were more likely to complete vaccination. Non-medical students (0.56, 0.43–0.73) and students studying in north-east China (0.28, 0.16–0.49) were less likely to receive a booster dose, while female students (1.51, 1.23–1.85) had a higher likelihood. The main reason for being unvaccinated was “contraindication” (75.00%), and the main reason for not receiving a booster dose was “being too busy to attend to it” (61.37%). This study demonstrated a high adherence to the COVID-19 vaccination policy among Chinese college students. Targeted strategies should be applied to remove barriers to COVID-19 vaccination among college students.
