* For most people in Canada, a “complete primary series” is two doses of either Pfizer, Moderna or AstraZeneca vaccine. Some individuals, including those who are immunocompromised, require three doses of the COVID-19 vaccine. Additional guidance on intervals between infection and vaccination for individuals who are moderately to severely immunocompromised, or children who have experienced multisystem inflammatory syndrome in children (MIS-C), are outlined in NACI’s updated guidance. Guidance on suggested intervals between infection and vaccination may change as additional evidence emerges. For more information, read our factsheet or visit halton.ca/COVIDvaccines. |
