Until now, no serious side effects have been observed in the world in both clinical trials conducted for the COVID-19 vaccines and in the routinely vaccinated population. Post vaccination side effects are often mild.
These mild side effects may include fatigue, headache, fever, chills, muscle/joint pain, vomiting, diarrhea, pain, redness and swelling around the area of injection. However, it should be noted that if any side effects other than those mentioned are to occur after vaccination, the nearest healthcare facility should be consulted and the physician should be informed that the vaccine has been recently administered, without ignoring the possibility of rare allergic reactions.
