EMA official: Clear link between AstraZeneca vaccine and rare blood clots in the brain
In an interview published on Tuesday, a senior official from the European Medicines Agency (EMA) said there is a correlation between AstraZeneca’s COVID-19 vaccine and very rare blood clots in the brain, but the possible causes are still unknown.
“It is now clear, in my view, that there is a connection between the vaccine and the disease. However, the cause of this reaction is still unknown “When asked about a potential connection between the AstraZeneca vaccine and cases of brain blood clots, Marco Cavaleri, chair of the EMA’s vaccine evaluation committee, told Italian newspaper Il Messaggero.
The EMA, according to Cavaleri, will say there is a correlation, but the regulator is unlikely to be able to say how old people should be given the AstraZeneca shot this week.
He did not offer any evidence to back up his claims.
A spokesperson for AstraZeneca could not be reached for comment right away. It has previously stated that the vaccine has not been linked to an increased risk of clots.
As it investigates 44 cases of an extremely rare brain clotting condition known as cerebral venous sinus thrombosis (CVST) among 9.2 million people in the European Economic Area who received the AstraZeneca vaccine, the regulator has repeatedly stated that the benefits outweigh the risks.
The vaccine is also endorsed by the World Health Organization.
The European Medicines Agency (EMA) announced last week that its investigation had found no clear risk factors for these extremely rare cases, such as age, gender, or a history of clotting disorders. The agency stated that although a causal link to the vaccine has not been established, it is probable and that further investigation is underway.
While several of the recorded cases involved young and middle-aged women, the European Medicines Agency (EMA) did not conclude that this group was especially vulnerable to AstraZeneca’s vaccine.
On Wednesday, the European Medicines Agency (EMA) will provide an update on its inquiry.
While the investigations are ongoing, several nations, including France, Germany, and the Netherlands, have placed the vaccine on hold for younger people.
Scientists are looking into a few theories to understand the exceedingly unusual brain blood clots that occurred in people after getting the AstraZeneca vaccine in the days and weeks afterwards.
One hypothesis proposed by European researchers is that the vaccine causes an unusual antibody to be generated in a small number of cases, whereas others are investigating whether the cases are related to birth control pills.
However, several scientists believe there is no conclusive proof, and it’s unclear whether or why AstraZeneca’s vaccine will cause a problem that isn’t shared by other coronavirus vaccines targeting a similar part of the virus.
In a separate interview, Armando Genazzani, a member of the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP), told La Stampa that the blood clots were “possible” to be linked to the AstraZeneca vaccine.
