The incidence rate of adverse reactions following COVID-19 vaccination among university students

Abstract

This study aimed to determine the incidence rate of adverse reactions following COVID-19 vaccination, as well as examine the influence of sex, number of doses received, days elapsed since vaccination, and past medical history. The survey involved students who participated in any of the three vaccination program sessions that took place at these universities. The participants noted their health statuses for eight days, including on the vaccination day itself, and provided demographic information and reports of any adverse reactions. An analysis of the surveys revealed incidence rates of pain at the injection site, swelling, fatigue, myalgia, and fever that all exceeded 50%. A generalized linear model analysis indicated a higher incidence in women than men, and a higher incidence following the second dose compared to the first. The incidence peaked the day after vaccination and gradually decreased over the following days. Those with medical histories of bronchial asthma and pollinosis were found to be associated with a higher incidence of adverse reactions. The findings of this study will hopefully contribute to public health data, particularly regarding university students—who have been under-represented in previous studies on this topic.
