This might be a case where we do in fact have to override the idiots and force it upon people. Endangering yourself with your own gullibility and stupidity is fine, but endangering myself or my loved ones? Nope.
I agree but consider Measles, much more infectious and hits children the hardest. As far as I know, there is no federal law requiring forcing a Measles vaccine on parents.
On the other hand, Covid19 is affecting the economy and we're not having any of that in the US after the shutdown devastation so maybe a law requiring a vaccine is in the cards.
edit: thinking about it for a second, i don't see a law requiring it working. The lunatics would go crazy, there would be states refusing to enforce the law. Maybe some sort of incentive would work better, like a federal tax credit for proof of vaccination or something.
There is absolutely no way the government is going to force this vaccine on people. Not in the land of the free. Not in the land of "face masks violate my rights" They could write all the laws they want - it'll be unenforceable without popular buy-in.
