Norway: AstraZeneca COVID-19 vaccine can cause blood clots due to extremely high levels of antibodies

On April 10, the Norwegian Radio and Television Company (NRK) reported that the Norwegian study pointed out that there is a link between the AstraZeneca vaccine and blood clots, but researchers still do not know which substances in the vaccine can trigger this side effect. The researcher studied 5 Norwegian patients aged 32 to 54 who had abnormal thrombosis within 10 days after vaccination with AstraZeneca. At the same time, the platelet count was low, and 3 patients died.

The study was published in the New England Journal of Medicine on the 9th. The results of the study showed that what the 5 patients have in common is that the antibody levels of the complex of platelet factor 4 (PF4) and polyanion are very high. These types of antibodies can activate and cause low platelet counts. Researchers call this vaccine induction. Immune Thrombocytopenia (VITT).

Ingvild Sørvoll, chief physician of the UNN research team in Tromsø, said: “This is a side effect of drugs, in which antibodies against heparin drugs are formed. However, these patients are not treated with heparin. . When we checked the literature, this antibody was never described after vaccination.”

Madsen, the medical director of the Norwegian Medicines Agency, said that it is not yet known what triggers this side effect, so this research is very important and provides a basis for further research.

Madsen said the study will influence the decision of the Norwegian Institute of Public Health (FHI) whether to re-vaccinate AstraZeneca.

It is reported that Norway stopped vaccinating AstraZeneca’s new vaccine in early March, and the Norwegian Institute of Public Health will announce on April 15 whether to re-vaccinate AstraZeneca.
