Safety & Side Effects

Tell your vaccination provider if you have any medical conditions, including:

  • any allergies
  • a fever
  • a bleeding disorder or are on a blood thinner
  • immunocompromised or are on a medicine that affects your immune system
  • are pregnant or plan to become pregnant
  • breastfeeding
  • have received another COVID-19 vaccine

Side effects that have been reported after COVID-19 vaccination include:

  • Injection site reactions: pain, tenderness and swelling of the lymph nodes in the same arm of the injection, swelling (hardness), and redness
  • General side effects: fatigue, feeling unwell, headache, muscle pain, joint pain, chills, nausea and vomiting, and fever

There is a remote chance the COVID-19 vaccines could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to four hours after getting a dose of either COVID-19 Vaccine. For this reason, your vaccination provider may ask you to stay at the place where you received your vaccine for monitoring after vaccination. Signs of a severe allergic reaction can include:

  • Difficulty breathing
  • Swelling of your face and throat
  • A fast heartbeat
  • A bad rash all over your body
  • Dizziness and weakness

These may not be all the possible side effects of COVID-19 vaccines. Serious and unexpected side effects may occur. The COVID-19 vaccines are still being studied in clinical trials.
