In Germany, one researcher thinks he has found what is triggering the clots. Andreas Greinacher, a blood expert, and his team at the University of Greifswald believe 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.
Prof. Greinacher and his team has just begun examining Johnson & Johnson’s vaccine but has identified more than 1,000 proteins in AstraZeneca’s vaccine derived from human cells, as well as a preservative known as ethylenediaminetetraacetic acid, or EDTA. Their hypothesis is that EDTA, which is common to drugs and other products, helps those proteins stray into the bloodstream, where they bind to a blood component called p

The European Medicines Agency has said that, as of April 20, there have been 287 reports of rare blood clots with low platelets after administration of the AstraZeneca vaccine, eight with Johnson & Johnson, 25 with Pfizer, and five with Moderna. The clots are notable because many have occurred in unusual and deadly locations in the veins that drain the brain (known as cerebral venous sinus thrombosis) and the abdomen (known as splanchnic vein thrombosis).
