Thus this issue was chosen to be examined and help to measure the outcome and consequence of receiving the vaccine does. Studies on people with specific diseases have not been done in this study in which the complications and conditions are totally different and it is out of the discussion of this study and this statistic applies to adult or young people without considering sex or race. The study aimed to show how safe or risky covid-۱۹ vaccines are.Search Method: This review study was conducted on January ۱ in the Web of Science, Scopus, And Pubmed database on Randomized Controlled Trial Studies which were compiled in ۲۰۲۱, and ۵۲ results were obtained and Twenty-two articles were excluded from the study during the two filtering stages.Results: Pfizer, AstraZeneca, and Sinopharm vaccines were detected to be safe and the Sinopharm vaccine indicated a lower prevalence of adverse effects compared with the other vaccines. The qunsequenses of the vaccines including pain, redness, and swelling at the site of the injection was reported in ۳۴.۵۶% of the participants.

At the same time, they have side effects that are often non-fatal but sometimes cause death in a really small number of people. It is hoped that with the development of corona vaccines, this Fatality rate touches zero.
