A senior official from the European Medicines Agency 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 to the vaccine. However, we still don’t know what is causing this reaction, ”Marco Cavaleri, chairman of the European Medicines Agency’s vaccine evaluation team, told the Italian newspaper Il Messaggero on Tuesday.
He said, “In the next few hours we will say there is a connection, but we have yet to understand how this happens.”
The regulator is investigating 44 reports of an extremely rare clotting disease of the brain known as cerebral venous sinus thrombosis.
Cavaleri said the agency is still unable to provide guidance on what age the vaccine is safe at, although a high proportion of cases have occurred in young and medium-sized women.
AstraZeneca and regulators have repeatedly stated that the benefits outweigh the risks, finding that the blood clots were rare and occurred in 9.2 million people in the European Economic Area.
“Throughout the ongoing investigation, we remain firmly convinced that the benefits of the AstraZeneca vaccine in preventing COVID-19, with the associated risk of hospitalization and death, outweigh the risk of these side effects,” said EMA Managing Director Emer Cooke last month during a briefing.
Several European countries, including France, Germany and the Netherlands, have stopped using the vaccine as regulators investigate reports of blood clots.
