Safety Key Messages
Public Health Agency of Canada, Vaccine Safety Key Messages
Common reactions to vaccine(s) are mild and may include:
- itching and/or rash at the injection site
- headache or dizziness (less common)
Severe allergic reactions are very rare. The dangers of vaccine-preventable diseases are many times worse than the risks of a serious reaction to the vaccine.
Get medical attention immediately if you develop any of the following symptoms within 3 days of getting the needle:
- swelling of the mouth and throat
- trouble breathing, hoarseness or wheezing
- high fever (over 40⁰C/104⁰F)
- convulsions or seizures
- or any other serious reaction to the vaccine
