What are the side effects from the vaccine?

Side effects that have been reported with the COVID-19 vaccine include:

  • Pain, redness or swelling at the site of injection
  • Fatigue
  • Fever
  • Headache
  • Muscle or joint pain
  • Chills
  • Nausea
  • Swollen lymph nodes

For the two-dose vaccines (Moderna and Pfizer), one or more of these side effects are to be expected in up to 1-in-4 people after the first dose and 1-in-2 after the second dose. They generally occur the day after vaccination and are normal signs that the vaccine is working. You can take fever or pain relievers like acetaminophen or ibuprofen if needed or apply a cool compress to the injection site. Contact your healthcare provider if you are concerned or if the symptoms don’t go away within two days (48 hours).

About half of those receiving the Janssen vaccine experience one or more of the side effects listed above.
