Report summary updated January 19, 2024
- A total of 105,016,456 vaccine doses have been administered in Canada as of December 3, 2023, including 5,694,993 vaccine doses of XBB.1.5 vaccines and 9,948,907 doses of bivalent vaccines. Adverse events (side effects) have been reported by 58,712 people up to and including January 5, 2024. That’s about 6 people out of every 10,000 people vaccinated who have reported 1 or more adverse events.
- Of the 58,712 individual reports, 47,010 were considered non-serious (0.045% of all doses administered) and 11,702 were considered serious (0.011% of all doses administered). Among all adverse event reports:
- 1,044 were following bivalent vaccines, of which 783 were considered non-serious (0.008% of bivalent doses administered) and 261 (0.003% of bivalent doses administered) were considered serious.

- Most adverse events are mild and include soreness at the site of injection or a slight fever.
- Serious adverse events are rare, but do occur. They include anaphylaxis (a severe allergic reaction), which has been reported 777 times (1 report per 100,000 doses administered) for all COVID-19 vaccines across Canada. That’s why you may need to wait for a period of time after you receive a vaccination so that you can receive treatment in case of an allergic reaction.
