The expected change in recommendations comes following reports of rare blood clots in some immunized patients. Canada is expected to receive 1.5 million doses of this product from the United States on Tuesday.
The AstraZeneca vaccine has not been widely used in people under the age of 55 in this country. Some jurisdictions, such as Prince Edward Island, use part of their supply to immunize young people who work in areas of public contact such as grocery stores and convenience stores.

Health Canada has argued that the benefits of the AstraZeneca COVID-19 vaccine continue to outweigh the risks.
