Show where they didn't do safety checks-- lying muppet!
Show me where they did do bona fide safety checks. If they had done proper safety checks and health evaluations these vaccines would never had hit the market.
If they were effective people would not have contracted covid for a start. If they were effective - you would not have needed half a dozen boosters If they were safe - young healthy people wouldn't be dying in such a ''baffling'' way
Luckily the big farma manufacturers have dopes like yourself that will line up again for more booosters
