The committee now recommends mRNA boosters to people who received two doses of the Oxford-AstraZeneca vaccine, adults over the age of 70, front-line health-care workers with a short interval between their first two doses, and people from First Nations, Inuit and Metis communities.
The latest recommendation says the emerging evidence suggests vaccine effectiveness against asymptomatic infection and mild COVID-19 disease may decrease over time, and a booster could help restore protection.
By the new year, mandatory boosters all round.
