A senior official of the European Medicines Agency (EMA) said in an interview published on Tuesday that there was a link between AstraZeneca’s Kovid-19 vaccine and rare blood clots in the brain.

However, the EMA said in a statement later that a review of the vaccine was ongoing and that it was expected to announce its results on Wednesday or Thursday. A spokeswoman for AstraZeneca declined to comment.

“In my opinion, we can now say that it is clear that the vaccine is associated with a blood clot in the brain. However, we still do not know the reason for this reaction, “Marco Cavalli, chairman of the vaccination team at the EMA, told Italy’s Daily Il Masseiro.

The cavalry did not provide any evidence to support his comments.

A higher proportion of reported cases affected young and middle-aged rats, but the EMA did not conclude that there was a particular risk of the AstraZeneca pill.

Scientists are exploring a number of possibilities that may explain the blood clots in the brain that occurred in the days and weeks after receiving the AstraZeneca vaccine in individuals.

European researchers have put forward a theory that the vaccine activates an abnormal antibody in some rare cases; Others are trying to figure out if the cases are related to birth control pills.

But many scientists say there is no conclusive evidence and it is not clear whether the AstraZeneca vaccine targets this part of the coronavirus because the cause of an issue is not shared by other vaccines.
