As the province announced 587 new cases of COVID-19 on Thursday, it reported a second case of a rare blood-clotting syndrome called vaccine-induced immune thrombotic thrombocytopenia, or VITT, linked to the AstraZeneca vaccine. “This is a rare but very serious condition,” said provincial health officer Dr. Bonnie Henry. “We are following it carefully.” A Fraser Health man in his 40s is being treated for VITT and is in stable condition. A woman in her 40s in the Vancouver Coastal health region was the first case in the province, reported last week. About 227,000 first doses of AstraZeneca have been administered since the vaccine arrived in the province about two months ago, said B.C. Health Minister Adrian Dix. In Canada, about 28 cases of VITT have been reported.
