According to Radio German wave In Germany, researchers from the Greifswald Hospital in northern Germany announced that they have discovered the cause of abnormal blood clotting in the few people who received the AstraZeneca COVID-19 vaccine.
Consequently, the AstraZeneca vaccine appears to activate the immune system to produce an autoimmune antibody that can cause blood clots in the brain. The mechanism appears to be similar to how SARS-CoV-2 causes clotting in patients with severe COVID-19, but the risk with the vaccine is much lower.
The findings mean that doctors can treat people with blood clots with popular blood thinners, which have also been used in severe COVID-19 patients.
The treatment can only be used when vaccinated people have developed blood clots, the researchers said, and cannot be used as an early preventive measure.
The information has now been shared with hospitals across Europe.
Joint research work between the Greifswald Hospital, the Paul Ehrlich Institute (PEI) – German Federal Medical Administration and Austrian doctors It has not been published in a scientific journal, so it has not received comments from independent experts.
Based on the new findings, the German Society for the Study of Thrombosis and Haemostasis recommends that people who have been vaccinated with AstraZeneca with symptoms of headache, dizziness or decreased vision lasting more than 3 days need to see to a doctor.
On March 18, the European Health Authority (EMA) announced that “no direct link was found between the AstraZeneca vaccine and the blood clot” according to their information. “The benefits of the vaccine outweigh the possible risks,” the agency said.
After the new guidelines, Germany and many European countries began to resume the vaccination program with the AstraZeneca vaccine from March 19.
