Are you saying that there are people - lots of people - who will not be infected with covid if they are exposed to it? That seems to me to be what you are implying. That would be news to me.
Also since you asked the answer yes, it appears many people with T cells from previous coronavirus many time do have a pre existing natural immunity.
“Importantly, we detected SARS-CoV-2-reactive CD4+ T cells in ∼40%-60% of unexposed individuals, suggesting cross-reactive T cell recognition between circulating "common cold" coronaviruses and SARS-CoV-2.”
To be clear for everyone else, the link I have supplied on four occasions now has this in it, a few paragraphs from the top.
“natural immunity was a more potent shield than vaccines”
Of course he won’t acknowledge it, and just pretends the words aren’t there.
Don’t fall for this guy’s political agenda.
Clicking on the link you supplied does not produce a web page with that phrase or even just the words "natural immunity" by themselves.
Anyone can check it.
And you didn't answer the question: Doesn't a positive PCR test mean you have covid?
Jesus Christ, click the title link and it’s in the first paragraph.
Fuck
Why would I play your games when you’re still lying about natural immunity

you want to bar people from society even though they have a superior immunity to those who can move freely
It’s evil
