"Ontario will no longer give the AstraZeneca-Oxford COVID-19 vaccine as a first dose due to the risk of rare blood clots. Dr. David Williams, chief medical officer of health, said on Tuesday that the province made the decision due to an increase in cases of a rare blood clotting syndrome known as Vaccine-Induced Immune Thrombotic Thrombocytopenia (VITT) linked to the AstraZeneca vaccine. According to the Ontario health ministry, as of May 8, more than 853,000 doses of the AstraZeneca vaccine were administered with a rate of VITT of roughly 1 per 100,000 doses administered. The ministry said there have been increased reports of VITT, with a rate of 1.7 per 100,000 doses administered, over the last few days.
Dr. Jessica Hopkins, the chief health protection and emergency preparedness officer with Public Health Ontario, said there have been eight cases of VITT in Ontario as of May 8, 2021. She said the rate has gone from one in 125,000 to one in 60,000.
"When you look at risk on a population level, what we're really looking at is, overall, does this safety signal give us enough concern that we would preferentially choose other products at this point in time? And given that we're seeing the overall case numbers of COVID going down and an increase in the safety signal at a population level, it makes sense to pause Astrazeneca because the risk of severe outcomes with VITT shouldn't be underestimated."
Dr. Dirk Huyer, coordinator of the provincial outbreak response, said VITT is considered serious. "This is a serious side effect that could lead to serious health implications and potentially to people passing," Huyer said."
Die "bildungsnahen" Teilnehmer werden sicher eine Erklärung für die Diskrepanz der Zahlen zur Häufigkeit schwerster Astra-Nebenwirkungen (D <-> N, DK, CA) parat haben. Was die kanadischen Behörden da jetzt bekanntgeben ist bereits nah an den katastrophalen Zahlen aus N und Dk (und laut dem Artikel zudem im steilen Höhenflug).
