Lu Hua Chen, Victoria Ka-Ying Hui, Yi-Ching Victoria Lai, Richard Huan Xu, Yingqi Guo

TL;DR
This study explores factors influencing university students in Hong Kong to get vaccinated against COVID-19, finding that perceived risk and past flu vaccination history are key predictors.
Contribution
The study applies the Health Belief Model to understand vaccination intentions among university students in Hong Kong, revealing new insights into effective public health strategies.
Findings
Perceived susceptibility significantly predicts vaccination intention (OR = 2.98).
Previous influenza vaccine uptake positively correlates with vaccination intention (OR = 1.54).
The vaccination lottery program did not significantly influence vaccination intention (OR = 0.87).
Abstract
The fifth wave of COVID-19, driven by the Omicron variant, started to surge in Hong Kong in December 2021. Previous studies have shown that younger adults, compared to older adults, are vulnerable to increased risks of side effects after vaccination. However, little is known about the COVID-19 vaccination behavior among younger adults, especially university students, in Hong Kong. Therefore, the present online survey study aimed to investigate the predictors of COVID-19 vaccination intention among university students in Hong Kong using the Health Belief Model (HBM) as a framework. Two other potential predictors, the previous influenza vaccine uptake frequency and the Hong Kong SAR government vaccination lottery program, were also examined. The intention to receive another dose of the COVID-19 vaccine was low (36.4%). Multivariate binomial logistic regression analysis showed that, after…
