Are you seriously going to just ignore the fact that Flu shots do not require VARES reporting on AE events whereas COVID vaccine shots DO require doctors to report events even if the doctor knows it to be unrelated? You dont think that would have a significant effect on the numbers huh?
Of course there is a fuzz factor.. No the presence of a fuzz factor doesn't invalidate it, yes citing data based on VARES is fine... **if** you know enough about statistics to actually **normalize** the data.. What you cant do is just take a raw number without normalization and expect it to mean something.
