European Medicines Agency (EMA) head of vaccines Marco Cavaleri admitted in an interview published Tuesday that there is a link between the AstraZeneca COVID-19 vaccine and blood clots, but the cause of “this reaction” is unclear.
“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,” EMA head of vaccines Marco Cavaleri told Italy’s Il Messaggero newspaper.
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.”
“We are trying to get a precise picture of what is happening, to define in detail this syndrome due to the vaccine,” Cavaleri said.
He added: “Among the vaccinated, there are more cases of cerebral thrombosis… among young people than we would expect.”
