As to be expected, given that these were technically massive trials. What doesn’t square with that however is that they ended their earlier trials early by claiming that the jabs were so effective it would be unethical not to give them to those who had the placebo. Thus, they made it impossible to track what should have been the earliest, tracked adverse reactions beyond a couple of months.
Good catch you can be sure any information that leads to prosecution has been buried or deleted long ago.
