The Johnson & Johnson vaccine used against the COVID-19 virus has now been linked to 28 blood clot cases and 3 deaths as per the latest records. Given an increasing in the rare blood clot cases, U.S. has decided that no J&J vaccines will be sent by the state.
As a result, many countries and states including the US, Ontario province of Canada, Norway, Denmark and other European countries have either paused or eliminated the use of J&J vaccine. Meanwhile, Australia has also recorded 5 new cases of blood clots due AstraZeneca Vaccine.
Certainly, scientists and medical experts have been working day and night to find out the reason behind the occurrence of blood clots. Finally, a researcher from Germany claims that he has found what about J&J vaccine is triggering clots. German blood Expert Andreas Greinacher, along with his team at the University of Greifswald say that the “so-called viral vector vaccines—which use modified harmless cold viruses, known as adenoviruses, to convey genetic material into vaccine recipients to fight the coronavirus—could cause an autoimmune response that leads to blood clots.” According to Prof. Greinacher, “that reaction could be tied to stray proteins and a preservative he has found in the AstraZeneca vaccine.”
Other than that, Prof. Greinacher has begun working on J&J vaccine as well. However, more than 1000 proteins have been identified in the AstraZeneca Vaccine, which is derived from human cells and a preservative known as EDTA. The researchers have hypothesized that EDTA helps those proteins stray into the bloodstream. There, they bind together with a blood component called platelet factor 4 (PF4), which results in formation complexes that activate the production of antibodies.
Researchers say when the inflammation caused by vaccines combine with PF4, it could trick the immune system and make it believe that the body had been attacked by a bacteria. As a result, it triggers an archaic defense mechanism that then runs out of control and causes clotting and bleeding.
These findings by Prof. Greinacher have been supported by Prof. John Kelton of McMaster University in Canada. Kelton’s outfit runs Canada’s reference lab for testing patients with blood-clotting symptoms after vaccination. He confirmed Prof. Greinacher’s findings and said that the lab has replicated some of Prof. Greinacher’s research. However, he stated, “(this) hypothesis could be right, but it could also be wrong”.
Now, Prof. Greinacher is working to confirm his theory.
