I worked in the past with the FDA and was impressed (not always in a positive way) with their attention to detail and their rigidity. With the mRNA vaccines (and even the intentional lack of treatment before the vaccine monotherapy) I was stunned at the lack of standards (as were Marion Gruber and Philip Krause who resigned as the heads of the FDA's vaccine division).
Danish researcher Stabell Benn and colleagues did a comparison of available Covid vaccines; the data presented on the mRNA vaccines (singly or pooled) from the Gold Standard EUA trials, double blinded and placebo controlled with over 70,000 subjects, showed ZERO protection from death (31 deaths in mRNA vaccine groups, 30 in controls. The British Medical Journal and others pointed to fraud in the Pfizer trials.) This was the Gold Standard clinical trial that the CDC/ FDA/ NIH were demanding of ivermectin and other well characterized drugs, which while prophylactic efficacy wasn't established (as with the Covid vaccines), had minimal acute toxicities (particularly compared to the Covid vaccines). The WHO declared glucocorticoids VERBOTEN, though published in March 2020 as effective by Chinese clinical immunologists (and also Standard of Care in Veterinary Medicine for all(?) mammals with serious respiratory viral infections). The wide range of toxicities by batch of the mRNA vaccines and the "accomodation" to switch storage conditions is not characteristic of the FDA I remember.
While there are always populational differences in adverse effects (for example carbamazepine is more dangerous to Han Chinese), the ranges of mRNA toxicities (1 in 800 hospitalized after the jabs in the UK, also high in Australia even before Covid appeared; while the CDC blanket dismissed all adverse effects with their "safe and effective" mantra. (When measles vaccines were introduced, Western Africa had lost about 20% of their children below age 6 to measles. There were "only" 400 children (immigrants?) lost to measles in the US annually; measles was an endemic childhood disease, eradicated from the US in 2000 (rubella in 2004; their vaccines should be travel vaccines, un-necessary to vaccinate every toddler for a conquered disease). Of course the measles vaccines reduced death from measles by over 90% in the vaccinated (strikingly different from the Covid vaccines).
The Big Question is why weren't the Covid vaccine roll-outs stopped or at least limited to those at most risk from the virus? The vaccine issues (un-necessary in healthy subjects under age 50; myocarditis and clotting disorders particularly in young healthy people; leaky with poor protection against infection and spread of Covid) were well known by summer of 2021. But rather than correct the situation, there was a doubling down (mandates!) with what Norman Fenton's data suggest was a placebo. Most of Europe has limited the Covid vaccines to the most vulnerable only. The US is pushing these vaccines in children (90% of whom by end of 2022 tested positive for SARS-CoV2 antibodies and thus have superior natural immunity.)
