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

Common side effects form the COVID-19 vaccine include: pain & swelling at the injection site and potentially fever, chills, tiredness and headache. These side effects should go away in a few days. More information about common vaccine side effects can be found here.

In most cases, discomfort from fever or pain is normal. Contact your healthcare provider:

  • If the redness or tenderness where you got the shot increases after 24 hours
  • If your side effects are worrying you or do not seem to go away after a few days.

If you get a COVID-19 vaccine and you think you are having a severe allergic reaction after leaving the vaccination site, seek immediate medical care by calling 911.
