I agree with keeping unvaccinated kids away from those who are not complete with vaccinations, to not treat said children? Are you ready to let a child die because the parents were too stupid to get the kid vaccinated? Please remember it is not the child's fault.

I think they won't have a problem finding a doctor who will treat their child, and the fact that the first doctor refused said treatment due to the vaccination issue might make them realize how big a mistake it was to not vaccinate them. They might reconsider and vaccinate their child because of this.
