Health Canada extends expiry of thousands of AstraZeneca shots by an additional month
TORONTO — Health Canada extended the expiry date of tens of thousands of Oxford-AstraZeneca COVID-19 vaccine doses by one month on Saturday, easing pressure on Canadians scrambling to get a second shot before the jabs went to waste.
That was most dramatically illustrated in Ontario, where pharmacists and physicians planned to work through the weekend to use up 45,000 shots expiring on May 31 and 10,000 more with a best-before date in June. Any injections formerly set to expire on Monday can now be used until July 1, according to Health Canada’s new guidance.
The government department stressed that the move is supported by ample scientific evidence. A Saturday statement said Health Canada received an application directly from AstraZeneca complete with “product stability and mathematical modelling data” showing that two lots totaling 49,000 shots could be safely and effectively used over seven months rather than the original shelf life of six.
“This change will ensure that provinces and territories are able to use up their existing inventory and provide Canadians access to much needed doses of the vaccine,” Health Canada said in a statement.
