Brief Summary

Numerous vaccination studies are conducted to protect against COVID-19 infection, and preclinical and clinical studies are still ongoing worldwide. During this extraordinary period, the necessity to perform COVID-19 vaccine studies and immunization programs together has emerged. Many manufacturing companies have started mass production of vaccines accepting the risk of failure of vaccines during trials. Vaccine Adverse Effects (VAEs) need to be documented quickly. We aimed to determine the VAEs and to compare the frequency of VAEs between groups according to socio-demographic characteristics after the inactivated vaccine (Corona Vac®) was administered to healthcare workers (HCWs) in Turkey. In this study, an online questionnaire was delivered to volunteer healthcare workers across the whole country. Sociodemographic characteristics, medical history, history of COVID-19 infection, and VAEs occurring after the first and second doses of inactivated vaccine were evaluated.
