Researchers say they might have discovered a factor for an unusual blood clot condition that has actually happened in some people who got the AstraZeneca COVID-19 vaccine.

” There is no other thing than the vaccine that can describe this immune response,” he stated.

Now, a group of German researchers, led by teacher Andreas Greinacher at the University of Greifswald, said on Friday in a statement that they believe the AstraZeneca vaccine, in many cases, triggers overactivation of platelets in the blood, which can then cause possibly fatal embolisms. They said its comparable to what occurs with a condition called heparin-induced thrombocytopenia.

Pushed by the local paper as to why hes so confident, Holme added that theres “no other history in these patients that can offer such a strong immune response. Im quite sure its these antibodies thats the cause, and I see no other reason than that its the vaccine that triggers it.”

They state receivers need to be on the lookout for uncommon bruising, swelling or headaches that start four or more days after getting the vaccination. If recognized quickly, they state, the clotting problem can be managed reasonably easily by health experts.

While Greinacher and his coworkers were studying the cases in Germany, researchers at the Oslo University Hospital were investigating 3 post-vaccination blood clots in Norway. All the Norwegian cases were health care workers under the age of 50. Among them has because passed away.

The German researchers state fortunately is that if their theory is proper, this rare negative reaction to the jab can be recognized and treated.

Greinacher and his colleagues evaluated the 13 cases of cerebral blood clots reported in Germany following the administration of roughly 1.6 million doses of the AstraZeneca vaccine in that country. While Greinacher and his associates were studying the cases in Germany, researchers at the Oslo University Hospital were examining three post-vaccination blood embolisms in Norway. On Friday, the EMA said that there is “no increase in total risk of blood embolisms” amongst people whove gotten the AstraZeneca vaccine. The European regulator stated it had reports of 25 embolisms so far amongst the approximately 20 million individuals whove gotten the AstraZeneca shot. “A causal link with the vaccine is not shown,” the EMA stated in a statement, “however is possible and is worthy of additional analysis.”

Greinacher and his coworkers evaluated the 13 cases of cerebral embolism reported in Germany following the administration of approximately 1.6 million dosages of the AstraZeneca vaccine in that nation. Of the 13 cases, 12 were ladies, and all the cases occurred between 4 and 16 days after the shot was administered. The EMA had also kept in mind that practically all the reported clotting occurrences remained in women under the age of 55.

” Our theory that this is a strong immune response that probably follows the vaccine,” Holme said. Its the exact same theory that Greinacher and his colleagues have advanced in Germany.

Greinacher and his colleagues state that in 4 of the patients, they were able to isolate and determine the particular antibodies that provoke the immune reaction leading to the cerebral embolism.

There were reports previously this month of approximately 30 blood clots happening after vaccination, a few of them fatal. This led more than a dozen European nations to suspend their use of the AstraZeneca vaccine.

The majority of nations resumed using it, however, after the European Medicines Agency carried out an examination and declared on Thursday that the AstraZeneca vaccine is safe and effective. The EMA stated the advantages of the vaccine far exceed the possible risks– and pointed out that the rate of post-vaccine embolism was actually lower than the expected rate in the basic population.

Two teams of European researchers, working independently, say they think theyve identified the reason for an uncommon blood clot condition that has occurred in some individuals after receiving the AstraZeneca COVID-19 vaccine.

Professor Pål Andre Holme informed the Norwegian paper VG that hes positive theyve identified antibodies prompted by the vaccine that caused an overreaction by the body immune system resulting in the embolism.

If correct, their research study might suggest any embolism that happen might be easily treated.

On Friday, the EMA said that there is “no boost in general threat of blood clots” amongst people whove gotten the AstraZeneca vaccine. The European regulator said it had reports of 25 embolisms up until now among the approximately 20 million people whove gotten the AstraZeneca shot. The EMA, nevertheless, didnt rule out a possible connection entirely. “A causal relate to the vaccine is not shown,” the EMA stated in a statement, “but is possible and is worthy of more analysis.”

Not everybody, including the European Medicines Agency, is persuaded that the reason for these clots has been found.
