Canada reports first blood clot possibly linked to AstraZeneca vaccine

Australia has abandoned a goal to vaccinate almost all of its 26 million population by the end of 2021 following advice that people under the age of 50 take Pfizer's COVID-19 vaccine rather than AstraZeneca's shot.

This comes after the United States made a decision to pause the use of the Johnson & Johnson vaccine also due to reports of rare blood clots.

The individual is at home recovering and Health Canada maintains that this is a "very rare" adverse event.

This week Australia abandoned a goal of vaccinating all of its almost 26 million population by year-end, after Europe's drug regulator reported rare cases of blood clots among some adult recipients of AstraZeneca doses, suggesting a link.

Health Canada approved AstraZeneca Feb. 26 and J&J March 5, but only AstraZeneca has been used here so far.


At a press conference on Tuesday, Prime Minister Justin Trudeau indicated that doses of this vaccine are expect to arrive at the end of April.

Earlier today the United States also paused use of the Johnson & Johnson vaccine following reports of six similar blood clots, and Health Canada says it has asked the drugmaker for more information on that vaccine as well.

When the European Medicines Agency ruled the benefits of the AstraZeneca vaccine outweighed the risks of side effects late last month, doctors pointed out the risk of blood clots from the vaccine was considered lower than what healthy women face while taking birth control pills. This prompted Australian officials to recommend that those younger than 50 receive the Pfizer Inc's vaccine in preference to AstraZeneca's shot, throwing the vaccination programme into disarray. It said it is working with the manufacturer, the US Food and Drug Administration and other worldwide regulators to determine the shot's safety as it awaits orders for up to 38 million doses.
