A senior official for Europe’s drug regulator said that 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 there is a link with the vaccine. But we still do not know what causes this reaction,” Marco Cavaleri, chair of the European Medicines Agency’s vaccine evaluation team, told Italy’s Il Messaggero newspaper on Tuesday.
He said that “in the next few hours, we will say that there is a connection, but we still have to understand how this happens.”
The regulator is currently investigating 44 reports of an extremely rare brain clotting ailment known as cerebral venous sinus thrombosis.
Cavaleri said the agency still won’t be able to provide guidance on what age is safe to receive the vaccine, though a high proportion of the cases occurred among young and middle-aged women.
