Maybe without a vaccination card or other pass that you're ineligible for the vaccine you get triaged right back out the door. That would help the hospital capacity, encourage vaccination, etc but it will probably need to get a bit more morgue capacity ramped up. Easier to train for.

The hippocratic oath prevents that fantasy.

That's why I called it triage. You can give steroids and O2 for home consumption? I guess it depends on the seriousness, on average, of the other people who are unable to use the hospital's services because it's overloaded and what their mortality rate is vs the unvaccinated who show up and are given some reasonable treatment to try, but not a bed. Not an easy decision or calculation to come up with.
