Abstract

Vaccination is an important strategy for controlling the coronavirus disease 2019 (COVID-19) pandemic. We conducted a web-based cross-sectional survey based on Google Forms to collect data on adverse events (AEs) after the first dose of the ChAdOx1 nCoV-19 vaccine for healthcare workers (HCWs). Among the 1,676 vaccinated HCWs, 59.5% (998/1,676) responded to the survey. In total, 809 (81.1%) respondents reported experiencing AEs. There were no serious AEs, such as anaphylaxis. The most common AE was pain at the injection site (76.2%), followed by fatigue (75.9%), myalgia (74.9%), and fever (58.4%). HCWs in the younger age group experienced significantly more AEs than in the older age group.
