Hush with all that 'natural immunity' nonsense; they're still trying to figure out how basic immunology works! However you can get an IgG bloodtest to prove immunity.. funny thing is, they will tell you that positive results can come from those with either a natural immunity or from the vaxx as to them, these are the same thing, at least that's the propaganda they're peddling. To that end, PCR is exactly the test they're still using, whether you're standing in line for 4 hours or you get OTC. only difference is one you can have results printed out, and the other you cannot.
