German Researchers Zero In On Cause of Vaccine Induced Thrombosis

is a complexing agent which reduces free iron ion concentrations to very low levels. I got taught about it back when I was doing an M.Sc. in inorganic chemistry.

It seems to be put into the AstraZeneca vaccine to "generate an inflammatory co-signal that further stimulates the immune response: EDTA in the vaccine increases capillary leakage at the inoculation site, likely by endothelial (VE)-cadherin disassembly".

The paper does suggest that the vaccine might still work without it.

Increased vascular permeability in response to immune cell activity at the infection site is a natural and necessary response in that it allows blood borne immune cells to leave the blood and access infected cell tissue. Extreme cases of this occur in the case of hemorrhagic viral infection such as Ebola. So this microvascular leakage is going to occur with or without the EDTA boost. There was an early theory about the thrombosis that hypothesized rare cases of vaccine misadministration that punctured capillary vessels causing the vaccine to enter the blood directly. The adenovirus will just as easily infect a platelet cell as any other cell, which would result in a quasi autoantibody being produced that attacks the resulting platelet/antigen combination. Apparently this EDTA is widely and heavily used in the cosmetics industry to enhance performance of skin/ hair care products. Seeing as nearly all the thrombosis victims are women, this fact is hardly a coincidence. These women probably already had leaky vascularity due to skin creams at the injection site prior to vaccination.

...shows, AstraZeneca contains EDTA, Pfizer does not. J&J and Sputnik probably have it too. None of the mRNA vaccines have it.

If it was the EDTA doing the damage then the people taking this alternative therapy offered below would all be dead!

EDTA is used in legitimate medicine treating lead and mercury poisoning and in crank medicine chelating other random elements. It isn't at all specific about what metal ions it will grab onto if no toxic metals are around. It is a legitimate antidote to them - benefits outweigh risks.

Dose makes the poison and the amount of EDTA in the vaccine is small compared to these other uses. I'd be very surprised if it were guilty.

EDTA is not killing them directly. It simply makes the microvascular walls more permeable to antigen proteins than normal. How the individual responds to the antigen/platelet interaction via this NET production is a personal matter.

But it would still kill many more when used in significant doses as below. Unusual blood clotting and platlet deficit isn't even mentioned as a side effect. Low calcium levels, kidney failure and death are.

You're missing the point entirely. EDTA has nothing to do with clot formation, it simply facilitates, through vascular leakage, the exposure of platelets to the vaccine viral antigen protein, and it's those proteins that set the lethal clotting process in motion. "Antigen formation in a proinflammatory milieu offers an explanation for anti-PF4 antibody production. High-titer anti-PF4 antibodies activate platelets and induce neutrophil activation and NETs formation, fueling the VITT prothrombotic response."

Are viral antigens present in this dumb chelation therapy? Not likely.
