People in the medical establishment, government , or the public who refuse to acknowledge the fact that immunity acquired as a result of a natural infection is either as good or better than that which is derived as a result of vaccination, thus being sufficient for proof of immunity.
Unbelievable that immunity deniers ignore all of the peer reviewed studies proving that acquired immunity is more robust than what can be had from the vaccine. This is medical tyranny. One should be able to get serology or titers tests and use that documentation as to their immunity status in the same way nursing schools for decades have allowed such documentation for MMR as proof of immunity.
