Below is an unedited message (highlights are mine!<\/em>) from Dr Mike Yeadon, former Chief Scientist and Vice-President of the Allergy and Respiratory Research Division of Pfizer, and is the co-founder and former CEO of the biotechnology company Ziarco.<\/p>\n Dear all, I am a card carrying\u00a0trained mechanistic toxicologist<\/strong>\u00a0(as well as a\u00a0biochemist<\/strong>, at least, that\u2019s what my degree certificate says).<\/em><\/p>\n More relevantly, I have over\u00a030 years experience<\/strong>\u00a0leading new drug design teams across the disciplines.<\/em><\/p>\n Over the life of the pharmaceutical industry, we have collectively learned a great deal what kind of chemical and biochemical structures confer what kinds of safety and toxicity risks.\u00a0We still miss things, especially when they\u2019re not understood<\/strong>\u00a0and all we have is harms\u00a0leading to abandonment of research projects<\/strong>\u00a0or even\u00a0withdrawal of launched products<\/strong>. Sometimes,\u00a0board level executives still don\u2019t withdraw harmful products<\/strong>\u00a0if they think there\u2019s some slight or arguable uncertainty & if they think they can get away with it.\u00a0Thalidomide\u00a0<\/strong>for example was sold in Spain deep into the 1970s, 15 years after it was unequivocally known to be a teratogen in humans.\u00a0Merck didn\u2019t withdraw their COX2 inhibitor<\/strong>\u00a0until it was so obvious that they were more or less going to get caught. Other times, companies behaved well.\u00a0<\/em><\/p>\n Equally, we have learned what kinds of design features confer good or poor absorption, low or high plasma protein binding, fast or slow oxidative or conjugative metabolic clearance of drugs via which pathways (hepatic to stool, renal to urine, etc). Drug disposition is perhaps the best understood to the extent there are AI systems which a century of medicinal chemistry & drug metabolism data has fed.\u00a0<\/em><\/p>\n Toxicology is much less well understood by the industry broadly, but students of the specialist field almost all of the well understood mechanisms of toxicity. Things like aspirin, paracetamol, paraquat, rotenone, masked anilines, certain free radical generators, planar polyaromatic hydrocarbons, etc etc. I\u2019ve forgotten so many.\u00a0<\/em><\/p>\n One classic example was dioxin release at\u00a0Seveso<\/strong>, Italy, which resulted in widespread harms from halogenated biphenyls, which injure us via the aryl hydrocarbon receptor, a nuclear factor controlling expression or repression of numerous genes. The underlying biology is extremely complex and I don\u2019t believe we can claim to understand it. We\u2019re not even sure what the endogenous ligands are.\u00a0<\/em><\/p>\n In one project in industry in which I was lead biologist, I noticed two chemistry colleagues had developed unusual facial rashes. I always pored over chemical structures, and noticed a plausible similarity between part of the new molecules that were being made & tested for this program and those industrial pollutants involved in the Italian accident. Sure enough, they had chloracne and it became a major incident, which we solved, killing the project (obviously) and teaching the industry worldwide to avoid close-in analogues.\u00a0<\/em><\/p>\n So when I looked at the purported vaccines,\u00a0I detected at least three distinct mechanisms of toxicity.<\/strong>\u00a0I assure you, not one of those features would have remained in molecules in the research teams armoury after the first project meeting. It wouldn\u2019t need to be me leading it. Any of my senior staff would see the\u00a0very obvious safety risks.\u00a0<\/strong>My peers in industry would also know of them. I\u2019ve talked about them in interviews, pieces to camera and affidavits.<\/em><\/p>\n No one has tapped me on the shoulder to explain why I\u2019ve got it all wrong. Several very clever people have independently said overlapping things, such as Professor Sucharit Bhakdi.\u00a0<\/em><\/p>\n Others with great expertise in intracellular signalling and molecular biology quickly spotted at least two other, clearly designed-in, obviously intentional,\u00a0mechanisms of toxicity (to do with nuclear localisation signals).\u00a0<\/strong><\/em><\/p>\n That makes at least five, independent, starkly obvious, in-the-structure harms<\/strong>. Based on at least some of these, I and doctor in Germany, Wolfgang Wodarg, wrote an open letter to the European Medicines Agency, prior to any such product being granted an Emergency Use Authorization. We listed several concerns for the kinds of harms we expected and feared would follow from mass administration to the population. In response to this letter, the media fell upon us both, we were smeared by our national broadcasters and pushed off numerous online platforms.\u00a0Within weeks of commencement of mass rollouts, all but one of our concerns were starkly obvious<\/strong>. The last one had to do with reproductive toxicity, which duly rolled in a year later.\u00a0 If you choose to disregard this testimony, I don\u2019t know what to say.<\/em><\/p>\n link to open letter to EMA:<\/em><\/p>\n https:\/\/doctors4covidethics.org\/urgent-open-letter-from-doctors-and-scientists-to-the-european-medicines-agency-regarding-covid-19-vaccine-safety-concerns\/<\/a><\/em><\/p>\n -Dr Mike Yeadon<\/em><\/p>\n This is Mike\u2019s official telegram channel:<\/p>\n https:\/\/t.me\/DrMikeYeadonsolochannel<\/a><\/p>\n Please share.<\/p>\n
