Its now discovered WHY. Its that 7% of adults have severe "PEG" allergy and all mRNA vaccines use PEG as a emulsifier and preservative. 0.6% of that 7% will die from it. PEG is polyethylene glycol, and not used intravenously before, and not in food, but is (or was) in some toothpastes. This woman died from PEG reaction but not mentioned in link: https://www.modernatx.com/mrna-technology/science-and-fundamentals-mrna-technology That woman died because of the exotic use of polyethylene glycol, and she is one of 7% of adults with severe polyethylene glycol allegies. And a polyethylene glycol glycol allergy is about 50 times more dangerous than a food allergy. It kills 0.6% of all such people, in studies. READ this long science article on PEG and vaccines : https://www.sciencemag.org/news/2020/12/suspicions-grow-nanoparticles-pfizer-s-covid-19-vaccine-trigger-rare-allergic-reactions All mRNA covid-19 vaccines use polyethylene glycol (PEG) and bind it to nanoparticles, and the mRNA is stuck under the PEG. SHE DIED NEEDLESSLY due to wanton use of polyethylene glycol causing anaphylactic reaction. SOLUTION? Blood pressure can be restored in a ER if patient is monitored for a full hour after getting injected, after that, if too many hours goes by, its a death sentence, even in a hospital ER. SOLUTION for now? STOP TAKING VACCINES using mRNA and PEG. This week, as I type this, 6 countries (not USA!) jsut started a 2 week ban on PEG vaccines! All due to this 0.6% mortality. SOLUTION for 2023 : A antibody test for PEG sensitivity can ban 7% of humans from taking the vaccine. A cheap 4 dollar prescreen instant test. If the 7% still want a shot... a second test of those 7% can test for the SECOND component of what causes only some of the 7% to die (only 0.6% of those 7% die so its something in addition. A second unproven mystery cofactor as in my link). 6 countries now ban this vaccine for creating 10 times more deaths from "reaction" vs other vaccines. But now we all know its PEG and not a mystery.
