It wouldn't be explicit turning away, but if your in a triage situation, most doctors and medical systems will focus on the most time serious and the people they are most able to save if they have limited capacity. And if your not vaccinated, the ability to save you will be less than the vaccinated and the people with other acute medical issues that are not COVID. That is what will happen in practice in such a regime.

Is there any evidence that this is true at the point of presenting with equal acute symptoms? Sure, your symptoms are likely to be less acute if you are vaccinated, but that's not the issue, the issue is response to treatment given similar symptoms.
