Health Canada has given the green light to an eagerly anticipated fall COVID-19 booster shot in hopes of bolstering the nation’s defence against the virus as the fall season approaches.
The health regulator on Tuesday approved the updated vaccine made by Moderna for all Canadians aged six months and older. Approval for the updated Pfizer vaccine under review has not been announced.
The updated mRNA vaccine is tailored to the XBB.1.5 Omicron subvariant that is circulating in the country. It also has additional sequences that target other Omicron variants.
Health Canada posted the decision on its website Tuesday morning, stating the vaccine can be given as one dose for people five years and older, regardless of their COVID-19 vaccination history.
For those six months to four years of age, one dose is recommended for those previously vaccinated against COVID-19, according to the product label. Two doses should be given to those in that age group who have not been previously vaccinated.
The approval comes as new COVID-19 variants — BA.2.86 and EG.5 — circulate the country, raising concerns about the effectiveness of existing vaccines and the need for continued vigilance in public health measures.
This comes a day after the United States approved updated COVID-19 vaccines. The shots from Moderna and Pfizer are available to most even if they’ve never had a coronavirus vaccination. The Centers for Disease Control and Prevention still must sign off on the vaccinations, which is expected to come Tuesday.
On Sept. 6, Pfizer said its new COVID-19 vaccine elicited a strong antibody response against the highly mutated BA.2.86 variant of the coronavirus in a preclinical study in mice.
Moderna also said clinical trial data in humans showed its updated shot will likely be effective against the variant.
The National Advisory Committee on Immunization (NACI) has previously recommended Canadians roll up their sleeves for the updated booster in the fall if it has been at least six months since their last dose or COVID-19 infection.
