I would have no problem prioritising ICU beds for vaccinated citizens (suffering from whatever illness they may have) over non vaccinated citizens (due choice, not medical impediment) afflicted by COVID - they've made their choice.
And what if the non-vaccinated citizen does not have his or her 'Vaccination Passport' or Medicare Card in the pocket of their trackpants when run over at a pedestrian crossing and taken by ambulance, unconscious and critically injured, to an ICU?
If you can quote me an ICU doctor or nurse who's explained how they can practically work out who is voluntarily unvaccinated when presenting to an ICU, please post the link.
And what of children who've just complied with whatever their parents have decided about vaccination?
