Christian Bogdan (Christian Bogdan) member of the German Vaccine Council said that the very rare incidence of blood clotting among women under 60 who received the AstraZeneca vaccine was 20 times higher than expected.
His comments came after the European Medicines Agency (EMA) and the British medical regulatory agency recognized a possible link between the AstraZeneca vaccine and the rare blood clot associated with low platelet counts. EMA conducted a detailed review of 86 blood clots, including 18 deaths.
Most people suffering from blood clots are women. However, of the 34 million doses received, EMA only reported 169 blood clots, indicating that they are rare. In contrast, due to oral contraceptives, 4 out of 10,000 women will develop blood clots.
Bogdan did not specify how many blood clot cases there are in the normal population, but he said that a higher prevalence in a population over a period of time is a very obvious red flag.
He said at an online conference organized by the Science Media Center: “We used the number of cases in society as a background incidence rate and compared it with cases observed between 4 and 16 days after vaccination.”
Bogdan added: “With this in mind, your ratio shows that among women aged 20 to 59, the proportion of women is 20 times.”
The German committee recommended last week that people under 60 who received the first dose of AstraZeneca should receive a second dose of another vaccine. Health experts at the online conference said that more research is needed to find out what causes people to form blood clots and the exact mechanism that causes them to form blood clots.
