Ontario reports 1st fatal case of rare blood clot after man received AstraZeneca COVID-19 vaccine

The Ontario government has reported the first fatal case of an extremely rare blood clot that has been detected in a small number of residents who received the AstraZeneca/COVISHEILD COVID-19 vaccine.

Dr. Barbara Yaffe, Ontario’s associate chief medical officer of health, made the announcement during a news conference at Queen’s Park Tuesday afternoon.

She said a man in his 40s developed vaccine-induced immune thrombotic thrombocytopenia (VITT) after receiving his first dose of the vaccine at the end of April and died a few weeks later.

“The risks associated with this vaccine are rare, but they are real,” Yaffe said, encouraging people with questions to contact their medical providers.

To date, more than a million people in Ontario have received the AstraZeneca vaccine and in total there have been 13 publicly confirmed cases of VITT.

This is a developing story that will be updated throughout the afternoon.
