Provinces and territories are expanding eligibility for fourth doses of the COVID-19 vaccine to millions more Canadians.
This week, the National Advisory Committee on Immunization recommended that second boosters be administered to residents aged 70 and over.
Here's where things stand so far:
NEWFOUNDLAND AND LABRADOR: Fourth doses are available to immunocompromised people at least 22 weeks after their previous dose.
NEW BRUNSWICK, NOVA SCOTIA AND P.E.I.: All are working on updating guidance, with announcements expected in the coming days.
QUEBEC: Fourth doses are being given to anyone 70 and older, long-term care home and retirement home residents and immunocompromised people. Those aged 60 and older are to be eligible for a second booster starting next week.
ONTARIO: Fourth doses are open to anyone 60 and older at a recommended interval of five months after the initial booster shot; First Nations, Inuit and Métis people and their non-Indigenous household members aged 18 and older; long-term care home and retirement home residents; and immunocompromised people.
MANITOBA: Fourth doses are being offered to residents of personal care homes and elderly persons supportive housing and assisted living; people aged 70 or older who live in the community; and First Nations, Inuit and Metis people aged 50 or older, regardless of where they live. The province said the second booster should be given at least six months after the last booster dose.
