The real question is mandatory vaccinations for covid19.
I've noticed that in every thread about mandatory vaccinations for covid19, it tends to dissolve into justifying the vaccination, not discussing the mandatory aspect of it anymore (along with the usual insults).
No mandatory vaccinations without exception rules otherwise you will violate constitutional rights.
Exceptions would include religious, health of the person (some folks cannot get them due to allergies and other health concerns), and like we currently have for the anti-vaxxer idiots who don't trust any vaccination at all, exceptions for stupidity. There also cannot be a "show me your papers" law from the Feds.
