Vax passports were not implimented in Florida as you say. However they were required in interstate commerce by some states. The US feds and Canada created vax passports by executive order for cross border commercial traffic which resulted in a revolt by independengt truckers in Canada and seizure of two high traffic border crossings...one in ALberta and the Other on the Freedom Bridge ( Windsor Ontario, cross border auto parts etc)
THis revolt actually pushed back on vax passports all across America and Canada,,,,the lefty deep state knew they had a powder keg and retreated in their unconstitutional , assinine totalitarian methods. Few knew how vast the push aganst our freedoms truklt were until we examined how Sweden handled its reaction to Covid. THey put freedoom first.We did not.
The Florida Grand Jury could examine how its commerce was afected by trucker vax mandates and deterioration of the supply chain.
Good point about vax passports at the border. The grand jury is going to be around for a while so they may get into other issues while being stonewalled by the feds..
I forgot that universities were big implementors of vax passports using phone apps.
