A Brief Reflection on the Side Effects of COVID-۱۹ Vaccines

Less than two years after the COVID-۱۹ epidemic, several vaccine candidates received emergency use permits in a wide range of countries. During the general vaccination, due to the diversity in the target groups, the presence of people with underlying diseases, and vaccination of a large number of persons in a short period of time, the probability of complications attributed to vaccination and causing concern in society is higher than normal conditions. To date, there was no evidence of a causal association between COVID-۱۹ vaccines and death. The side effects of injectable vaccines have not been widely observed in recipients. However, some vaccine recipients have experienced complications such as gastrointestinal disorders, skin allergies, and even platelet clots. For example, only a few cases of anaphylaxis have been reported after receiving Pfizer-BioNTech and Moderna COVID-۱۹ vaccines. Health authorities recognize that all of authorized COVID-۱۹ vaccines can cause side effects. In general, researchers believe that the benefits of COVID-۱۹ vaccination outweigh the side effects associated with it. This review summarizes the known side effects of the ۸ authorized COVID-۱۹ vaccines and provides insight into risks that researchers are still investigating.
