AstraZeneca Blood Clots

AstraZeneca-linked blood clot confirmed in Alberta: Hinshaw

Apr 17, 2021 | 10:43 AM

Alberta’s chief medical officer says the province has confirmed a rare blood clot case in a patient who received the Oxford-AstraZeneca vaccine.

Dr. Deena Hinshaw says the patient, who is in his 60s and is recovering, marks the second Canadian case of the blood clot disorder known as vaccine-induced immune thrombotic thrombocytopenia, or VITT.

More than 700,000 doses of the AstraZeneca vaccine have been administered across Canada to date.

“The global frequency of VITT has been estimated at approximately one case in 100,000 to 250,000 doses of vaccine,” said Dr. Hinshaw, in a statement issued Saturday morning.

“In comparison, Albertans 55 and older who are diagnosed with COVID-19 have a one in 200 chance of dying from that infection. They are also at least 1,500 times more likely to be hospitalized from COVID-19 than experiencing VITT after getting AstraZeneca.”

Hinshaw says the second case does not change the province’s risk assessment, and that she continues to recommend the AstraZeneca vaccine for anyone 55 and older.
