Some patients who receive the COVID-19 vaccine may develop minor side effects. Fever, headaches, and body aches are typical COVID-19 vaccination adverse effects, as are aching arms. Usually, these symptoms disappear after a day or two. Rest, a lot of non-alcoholic beverages, and, if necessary, taking medicine to control pain and fever will help you manage any side effects.

Contact your healthcare practitioner immediately if you have trouble breathing, chest pain, confusion, loss of speech, or mobility following your vaccination.
