More than half of Canada’s AstraZeneca vaccine doses expired, will be thrown out
OTTAWA — Canada is about to toss more than half of its doses of the Oxford-AstraZeneca COVID-19 vaccine because it couldn’t find any takers for it either at home or abroad.
It also has yet to explain how it plans to manage millions of doses of both Novavax and Medicago vaccines that it bought but is unlikely to use itself.
Canada signed a contract with AstraZeneca in 2020 to get 20 million doses of its vaccine, and 2.3 million Canadians received at least one dose of it, mostly between March and June 2021.
Following concerns in the spring of 2021 about rare but potentially fatal blood clots from AstraZeneca, and with more ample supplies of the mRNA vaccines from Pfizer-BioNTech and Moderna, Canada moved away from using AstraZeneca. In July 2021, it promised to donate the rest of its procured supply, about 17.7 million doses.
