What are the side effects of the COVID-19 vaccine?

After you get the COVID-19 vaccine, you may have pain and swelling in the arm where you got the shot. You may also feel tired or get a fever, chills, or headache. Side effects are a normal sign that your body is building up protection against COVID-19. They should go away in a few days. Currently, both available COVID-19 vaccines require two shots for full immunity. If you have side effects after your first shot, you should still get the second one unless your doctor or vaccine provider tells you not to. Rarely, COVID-19 vaccines can cause a severe allergic reaction that requires emergency treatment. If you believe you are having a severe allergic reaction after receiving a COVID-19 vaccine, seek care immediately by calling 911.
