Ontario’s first AstraZeneca-related blood clot confirmed by provincial health officials

Man in his 60s recovering at home

Ontario’s Chief Medical Officer of Health has confirmed Ontario’s first vaccine-induced blood clot. This would mark the fourth such case in Canada.

A man in his 60s developed the rare condition, known as vaccine-induced immune thrombotic thrombocytopenia (VITT), after receiving his first dose of the AstraZeneca vaccine which has been under scrutiny for causing VITT elsewhere.

“While these serious reactions remain extremely rare, we have a robust process in place to monitor for any adverse events and have taken steps to ensure that these events are identified and treated as quickly as possible,” said Dr. Williams on Friday.┬áThe patient has received treatment and is recovering at home. Additional details will not be publicly released to protect the patient’s privacy.”

Ontario continues to offer the AstraZeneca vaccine to anyone 40 years of age or older. “The Health Canada approved vaccines are the best way to protect your health and those around you,” concluded Williams. “Ontarians are encouraged to get vaccinated as soon as they are eligible and monitor their health after receiving their vaccination.”

Over 2.3 million AstraZeneca vaccine doses have been distributed across Canada to date. On Friday, the National Advisory Committee on Immunization recommended the AstraZeneca vaccine be administered to those 30 years of age and up. The move has yet to be approved by the government.
