Scientists have found out the cause of blood clots after vaccination with AstraZeneca

A group of scientists from the United States and the United Kingdom have found out the probable cause of thrombosis, which in some cases were recorded after vaccination against coronavirus infection with the drug company AstraZeneca. This is stated in a study published in the scientific journal Science Advances.

Blood clots may be influenced by how the adenovirus, which is used in the AstraZeneca vaccine to transfer infection genetic material into cells, binds to a specific protein in the blood known as platelet factor 4 (PF4), according to experts. It is noted that the binding process causes a chain reaction in the immune system, which leads to the formation of blood clots.

The scientists emphasized that thrombosis after vaccination appears in extremely rare cases, since a whole chain of complex events must occur for them to occur.

Earlier it became known that production of the drug for the coronavirus AstraZeneca began in Russia. This was announced by the First Deputy Minister of Industry and Trade of Russia Vasily Osmakov. The pharmaceutical company “R-Pharm” is engaged in the release. According to him, the use of only domestic vaccines will continue on the Russian market.
