Not really, those people go to a hospital where there is a duty of care. Hospitals don't get to just say "Nah, not gonna help you" and close the door for people showing up in the ED.

So those vaccine deniers get sick, lose their commitment, go to the ED, get some level of treatment/help/etc, and suck up resources and impact help for the guy who got vaccinated then got hit by someone running a red light....
