Considering how limited the trials were, it's difficult to conclude the wider number would be vanishingly small, given even just one or two incorrect exclusions of vaccine-caused injury, which could reasonably happen even by chance.
Given the context that Pfizer has been repeatedly tried and criminally convicted for highly unethical practices and fined in the billions for it - along with the rest of big-pharma - it's unfair to regard the suspicious as "fucking idiots".
Certainly, the characterisation offends me, as I personally know multiple people who were definitely injured directly by the COVID vaccine, of every major variety: Pfizer, Astra Zeneca, and Moderna.
Statistically, that should simply not be the case, were these "mRNA" injections as safe as they were marketed to be.
