This is the cause of clots after the corona vaccine

Corona vaccine and clots … and an endless cycle of questions As scientists around the world race to understand that Corona virus vaccines from AstraZeneca and Johnson & Johnson cause rare but deadly blood clots, after recording a number of cases, which angered some and did not hesitate in taking vaccinations.

The German researcher, Dr. Andreas Grencher, found that the chemical in the “AstraZeneca” vaccine leads to an immune reaction that produces those rare side effects that were recorded in a few people who received the vaccine.

He also explained that a preservative in the “AstraZeneca” Covid-19 vaccine may lead to a rare overreaction of the immune system that causes blood clots, according to what was reported by the “Wall Street Journal.”

A preservative in the vaccine may be the cause

The German professor and his team identified more than 1000 proteins in the human cell-derived AstraZeneca vaccine, as well as a preservative known as ethylenediaminetetraacetic acid, or EDTA, that may trigger an excessive immune reaction by forming clumps using platelets in the bloodstream.

He also explained, that the inflammation caused by vaccines, in addition to PF4 compounds, can fool the immune system into believing that the body has been infected with bacteria, which leads to an old defense mechanism that gets out of control and causes clotting and bleeding.

The theory holds true and false

Professor John Kelton of McMaster University in Canada, whose group runs a reference laboratory to screen patients with symptoms of blood clotting after vaccination, said the lab had replicated some of Grincher's research and confirmed his findings.

However, Kelton explained that the reasons are not yet "sufficiently clear", noting that Greencher's hypothesis may be correct, but it may also be wrong.

Some scientists believe viruses themselves could play a role in triggering the condition because they are linked to blood clotting. Others speculate that infected people could have a genetic predisposition, or that their immune systems had previously developed the problematic antibody.

Vaccine-related clots are rare

And the World Health Organization announced, last April, that the link between the AstraZeneca vaccine against the Corona virus and the emergence of a rare form of blood clots is “possible, but not certain.”

WHO experts in the field of vaccines said earlier that it is necessary to conduct specialized studies in order to fully understand the potential link between vaccination and possible risk factors, pointing out that these phenomena are very rare despite being alarming, knowing that more than 200 million people have received the AstraZeneca vaccine - Oxford
