Once again, I think the issue is why not follow the science?
Do you agree that natural antibodies are just as effective, and possibly much more effective, that the vaccine? Likely to last much longer and cover a wider variety?
Why doesn't a positive antibody test carry the same weight as a vaccine card? Hell, the vaccine card could be fake for all you know. These frontline workers that had Covid have immunity.
Viral loads seem to be higher in the vaccinated so is it at least possible that those with natural immunity could be safer to the patient than someone who only received a vaccine?
This seems rather logical to much of the population. Europe accepts antibodies as equal to vaccination. Why don't you, or your health system? It is the decisions by the NBA and healthcare systems like yours to fire needed, qualified workers that raise suspicions that all is not above board.
