The European Medicines Agency confirmed today that there is a link between AstraZeneca and abnormal blood clots, but emphasized that its benefits still outweigh the risks of side effects.
“After investigating dozens of cases of blood clots after the EU vaccination against AstraZenec, the EMA Safety Committee concluded that the benefits of AstraZeneca outweigh the risk of side effects. Covid-19 is a very serious disease that occurs every day in Europe. Hundreds of people were killed. European Union: EMA Director Emer Cooke said: “This vaccine has proven to be very effective and can prevent hospitalization and serious illness. This vaccine can save lives and is extremely important in the fight against COVID-19. “
EMA investigated 86 reported cases of clot formation. In the European Economic Area composed of the European Union, Iceland, Liechtenstein and Norway, AstraZenecom has vaccinated 9.2 million people.
In the United Kingdom, as of March 24, 30 vaccinators have been confirmed, of which 18 million have died.
Cook said: “We came to the conclusion that the rare combination of blood clots and low platelets should be listed as possible rare side effects of the vaccine.
Cook said: “When millions of people are vaccinated, there may be very rare side effects that have not been observed in clinical trials. This shows that our surveillance system is working. These very rare events have been confirmed. .”
According to reports, within two weeks of vaccination, most reported cases of blood clots occurred in women under 60 years of age.
Said at a press conference: “Our investigation concluded that blood clots are a very rare side effect of the AstraZeneca vaccine.”
“Most cases are reported in women under the age of 60, but based on current evidence, no specific risk factors have been identified, such as age, sex, or previous medical conditions for thrombosis. Blood clotting was reported in all groups. AstraZeneca will Other studies are needed to investigate the occurrence of blood clots,” EMA said.
Peter Arlett, an EMA official in charge of data analysis, compared the risk of AstraZeneca vaccine use with the contraceptive pill, which can also cause coagulation cases in a small amount on a large scale, but is still used.
EMA reports that one possible explanation for the combination of blood clot formation and low platelet counts is that “the body’s immune system reacts to conditions similar to those sometimes experienced by patients receiving heparin (heparin-induced thrombocytopenia or HIT). situation.”
EMA investigates reports of brain clots in rare cases called cerebral venous sinus thrombosis (CVST).
In the United Kingdom, as of March 24, 30 vaccines have been confirmed, of which 18 million people have died, including 7 deaths.
Reuters reported that European health ministers met later today after the EMA announcement, and previously announced that the European agency’s decision on vaccine safety will directly affect the vaccination plan and coordinated response.
