There was no way to trust someone saying "I have natural immunity, I had COVID" when the crisis was happening, even more given how it was used politically to fan the flames for political gain.

Stop thinking about individuals, think about systems, and societies.

Given that people were refusing basic instructions (keeping distance, for example); that people dying of COVID in a hospital didn't believe the disease was real due to political influences; how do you think governments and their healthcare systems would be able to track if someone had natural immunity or not? There's no way, the only answer is: vaccinate as many people as possible to cover for uncertainties.

Again, it's a numbers game, in a fast moving crisis there's no opening for individualised actions, you are part of a larger whole and the larger whole required for people to get vaccinate to stamp off the crisis.

You could trust them by letting them show you a blood test that showed antigens.

You still only think in individual terms, you are not at all engaging in this discussion with any kind of systems thinking...

All healthcare resources were stretched thin during the height of the pandemic, your proposal is to add yet another resource-intensive test? For what exactly? So people could skip taking the jab? Don't you see any issues with the cost-benefit analysis of this? Not even accounting for the fact of how easy would be to defraud it.

People were faking vaccination cards, faking a blood test showing antigens would be another very common fraud. You cannot trust people when the consequences are much greater than any individual issue...
