Canadian health authorities announced Saturday that they were rolling back the expiration date of nearly 50,000 doses of AstraZeneca coronavirus vaccine in a month.
“This change will ensure that provinces and territories can use their existing inventory and provide Canadians with access to much-needed doses of the vaccine,” the agency said.
A Health Canada spokesman said as of May 22, there were about 49,000 doses of AstraZeneca in the country that expired on May 31. CBC reported that most were in the province of Ontario.
The Canadian health authorities had previously approved a six-month period service life for the Covid-19 vaccine from AstraZeneca.
But they said they received information from the company on May 27 that included “product stability data and mathematical modeling” that showed the two batches could be used safely and effectively for another month.
Several provinces have announced this month their decision to suspend the use of the AstraZeneca vaccine for people receiving their first shot, due to rare cases of blood clots.
But Canadians who had received a first dose of AstraZeneca were able to get their second scheduled dose.
Just over 55 per cent of Canada’s 38 million people have received a dose of Covid-19 vaccine and 5 per cent have received two doses.
In addition to AstraZeneca, Pfizer, Moderna and Johnson & Johnson vaccines are approved for use in Canada.
