Potential side-effects

The COVID-19 vaccines stimulate a strong immune response that may cause mild and temporary symptoms in many individuals for 1-3 days. These are normal signs that your body is building protection:

  • pain and swelling at the injection site

  • fever   

  • fatigue

  • chills

  • headaches

  • muscle aches           

  • nausea

Once you are fully vaccinated:

  • You are not required to quarantine or get tested following a known exposure, as long as you don't have symptoms of COVID-19.

  • You can travel domestically without pre- or post-travel testing or self-quarantine.

  • You should still get tested if you experience COVID-19 symptoms.

You are considered fully protected two weeks after your final dose of a COVID-19 vaccine. For the Pfizer or Moderna vaccine, this means two weeks after the second dose. For the Janssen (J&J) vaccine, this means two weeks after the single dose.
