> It was an objective public health measure, because it is well-known from actual examples that opening such option would lead people to try to get infected instead of being vaccinated, breeding even more variants and hospital saturation.

Bullshit.

> Note also that "previous contamination" has never been an acceptable derogation in any public health system for any of the compulsory vaccinations.

Nonsense. Literally the first example I looked up was the CDC's measles vaccination advice https://www.cdc.gov/measles/hcp/vaccine-considerations/index... : laboratory confirmation of immunity or of the disease is considered presumptive evidence of immunity in exactly the same way that a vaccination record is.
