Canadian health authorities announced on Saturday their decision to postpone the expiration date of nearly 50,000 doses of AstraZeneca vaccine, which expired on May 31, by one month.
Health Canada has assured in a statement that its approval of a thirty-day grace period from May 31 to July 1 of the “expiry date of two batches of AstraZeneca” is “based on scientific evidence.” The change “will allow provinces and territories to use their existing stocks,” the Ministry of Health said.
A Health Canada spokesman said there were about 49,000 doses of AstraZeneca in the country as of May 22, with an expiration date of May 31. According to the CBC channel, a significant proportion of these doses are to be used in Ontario.
55% of the population received one dose and 5% received two.
The country’s health authorities have approved a six-month shelf life for the AstraZeneca Covid-19 vaccine. They point out that they received a document from the company on May 27, “containing product stability data and mathematical model data that demonstrated that the quality, safety and efficacy of the two batches in question would be maintained over a period of time. … an extra month, but only seven months. “
Several Canadian provinces announced in May their decision to suspend the introduction of AstraZeneca serum as a precautionary measure for people receiving the first dose of the vaccine due to an increase in vaccine-related thrombosis. But it continues to be used by people who have received their first dose of AstraZeneca and want a second dose of the same product.
To date, approximately 23 million doses of the vaccine have been administered in Canada, with a population of 38 million. Just over 55% of the population received one dose and 5% received two.
In addition to AstraZeneca, vaccines from Pfizer, Moderna and Johnson & Johnson have been approved in Canada.
