I know several pilots who have been grounded, not because of the vaxx, but because they may have been exposed to someone who knows someone who may have been exposed to someone with covid. They then have to quarantine 10 to 14 days. This is worse than stupid.
I don't doubt that a bit, but others have been grounded because of vaccine induced Myocarditis and Pericarditis like my little brother. And the rate is far higher than the official statistics would suggest.
