Earlier quoted context omitted.
Nothing hypothetical about that, it’s generally how US healthcare works barring people being declared mentally incompetent, court ordered treatment, etc. To address the seeming contradiction. Vaccination was never imposed by the healthcare system on patients during COVID, it was required by cruse ships, schools, and yes hospitals for staff etc.
Which wasn't justified and should probably be an illegal requirement on privacy grounds. It doesn't make a difference if people doing work were vaccinated or not. It turns out to have had little in-practice effect on transmission, so the only important question is whether the passengers on things like a cruise were vaccinated themselves. They were evidence-free policies. We had a great natural case study in Australia…
I am from Australia and this is all nonsense.
a) Vaccines are not designed to prevent transmission. They are designed to stop people from getting seriously ill and dying.
b) Vaccines and lockdowns were vital in high-density areas like Victoria and NSW which saw health care systems almost instantly overwhelmed. This was then causing mass deaths for both COVID and non-COVID cases. It was a public health emergency by every definition.
c) COVID was only allowed to spread once enough of the population was vaccinated. And that was because instead of needing to go into hospital people could stay at home for a few days. And even then it has taken years for the system to recover.
