examining side effects of the sputnik v covid-19 vaccine

Background: as a result of the covid-19 pandemic, many vaccines were developed to counter the disease, including the vector-based sputnik v vaccine. this study aims to identify the side effects of the sputnik v covid–19 vaccine in a medical center and compare the results with the previous reports. methods: a questionnaire-based study was performed after the injection of the first and second doses of the vaccine to assess the side effects experienced by the participants. it was performed by reviewing similar previous studies. results: injection site pain, muscle pain, fever, fatigue, chills, and headache were the most common side effects of the vaccine. the incidence of major side effects decreased with age and was lower in men. in our study and others, the incidence of side effects was decreased in the second dose. in some studies, participants with a previous history of severe acute respiratory syndrome coronavirus 2 (sarscov-2) infection developed more side effects, especially injection site pain, muscle pain, and fatigue. conclusion: most studies agree with our reported results. serious side effects of this vaccine are rare and may be considered tolerable in adults.
