Who cares? Everyone has been vaccinated at this point unless you're so deluded from reality you missed the vaccination campaigns in every country on Earth.
A few years ago I got the 'rona and recovered. A few weeks later I went to doctor who got me blood test to confirm antibodies. He wrote letter stating I had it, I fully recovered, and the vaccines are not recommended. On a lark I got another antibody blood test recently and the markers are as strong as the first blood test - no waning.
