Individuals 6 months of age and older who never received a COVID-19 vaccine can be vaccinated. See table above or specific recommendations.

Individuals who are 5 years of age and older who are eligible can be vaccinated.

Anyone 12 years of age and older and were never vaccinated may receive either an mRNA (Pfizer XBB or Moderna XBB) or protein subunit (Novavax XBB) COVID-19 vaccine.

All other individuals are currently recommended to wait until fall 2024 for their next COVID-19 vaccine dose, unless otherwise advised by their healthcare provider. This includes individuals who are not at higher risk of severe illness from COVID-19 and who did not receive the XBB COVID-19 vaccine in fall 2023.

Vaccination if Immunocompromised

Receiving a vaccine is important for individuals who are moderately to severely immunocompromised and at increased risk of severe illness from COVID-19.

Moderately to severely immunocompromised individuals who are 6 months to 4 years of age who have not been previously vaccinated should receive an additional dose of vaccine to be fully protected. Follow Appendix B in the Ministry of Health’s guidance for number of doses recommended.

Moderately to severely immunocompromised individuals who are 5 years of age and older and never received a COVID-19 vaccine should receive 2 doses of COVID-19 vaccines. Please refer to Ministry of Health guidance for more information.
