A senior official at the European drug regulator said there appears to be a “clear link” between the AstraZeneca vaccine and blood clots.
“In my opinion, we can say it now, it is clear that there is a link with the vaccine. But we still don’t know what causes this reaction, ”Marco Cavaleri, chairman of the European Medicines Agency’s vaccine evaluation team, told the Italian newspaper Il Messaggero on Tuesday.
He said that “in the next few hours we will say that there is a connection, but we have yet to understand how this happens.”

EMA executive Emer Cooke. month during an information session.
Several European countries, including France, Germany and the Netherlands, have halted use of the vaccine while regulators investigate reports of blood clots.
