Possible Side Effects After Getting a COVID-19 Vaccine

COVID-19 vaccination will help protect you from getting COVID-19. You may have some side effects, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days. Some people have no side effects.

Common Side Effects

On the arm where you got the shot:

  • Pain
  • Redness
  • Swelling

Throughout the rest of your body:

  • Tiredness
  • Muscle pain
  • Headache
  • Chills
  • Fever
  • Nausea

  • Helpful Tips

    Talk to your doctor about taking over-the-counter medicine, such as ibuprofen, acetaminophen, aspirin, or antihistamines, for any pain and discomfort you may experience after getting vaccinated. You can take these medications to relieve post-vaccination side effects if you have no other medical reasons that prevent you from taking these medications normally.

    To reduce pain and discomfort where you got the shot

  • Apply a clean, cool, wet washcloth over the area.
  • Use or exercise your arm.
