Objectives Vaccines are one of the best interventions developed for eradicating COVID-19 the rapid creation of vaccinations was increased the risk of vaccine safety problems. The aim of this study to provide evidence on Sinopharm COVID-19 vaccine side effects. Methods A cross-sectional survey study was conducted between January and April 2021 to collect data on the effects of COVID-19 vaccine among individuals in the UAE. Demographic data chronic conditions side effects of the 1st and 2nd dose toward the vaccination, and the response of unwilling taking COVID-19 vaccine were reported. Results The most common side effects of post 1st dose (less than 49 years old vs >49 years) were normal injection site pain, fatigue, and headache while pain at the vaccination site fatigue lethargy headache and tenderness were the most side effects of the post 2nd dose in both groups. All the side effects in both doses were more prevalent among the participants less than 49-year-old group. Among females vs males side effects were more common in females compared with males in both doses in both doses. The most common adverse reactions of 1st dose in (females vs males) were fatigue lethargy headache while in 2nd dose were fatigue sever injection site pain. The most common reason of not willing to take the COVID-19 vaccine were the vaccines are not effective and they were not authorized to take vaccine.
