I doubt the state can ban a vaccine requirement. They’re private companies, if they require vaccination that shouldn’t be an issue. The CDC, government, requiring a private company to comply is a different issue. My guess, initially the lines probably prefer the vaccine requirement. A year from now I doubt it will matter. Though on a more serious level no different than restaurants, or ship dining rooms, requiring shoes and shirts.
These experimental shots like Moderna, Pfizer, Johnson and Johnson are not proven vaccines yet.
There has not been enough time elapsed to get covid -19 vaccine approval like polio-small pox-TB-etc. which over period of time are shown to be beneficial, and have FDA approval as a vaccine- which these experimental drugs don't have yet.
It may be that these experimental drugs are great in fending off the detrimental effects of the coronavirus but only time will tell.
Older people like myself (mid 80s) don't have to worry about detrimental consequences 10 years down the line , but much younger people certainly do.
Anyway it will be interesting to see how the CDC, politics ,cruising, vaccines, jobs and the economy play out in Florida. The Saga politically and economically continues.- TOM
