For all kinds of info about vaccines et al and I think RFKjr just won suit, go to

IIRC, HHS was supposed to be verifying annually safety. RFK Jr. requested copies of those reports using FOIA. After much delay, he took them to court, and they stated that they could not produce said reports.
So they either simply failed to do the due diligence they were supposed to do, or they are hiding the evidence, is my conclusion.
