This is very interesting. If proven we would need a method of identifying those with natural immunity and protect the others. But think that’s a long way away. However, it’s will also depend on how many people of the 25% non immune that means in reality.

I think given it's been here since October or November 2019 the reality is many locations are at herd immunity already & those not are close. There's a reason 17-21s testing positive they're one of the age groups that locked down the most as Uni/College/Secondary school closed

Those statements are entirely out of line with the fact that cases are increasing in most locations in the UK. Indeed, even ignoring cases and just looking at hospitalizations and deaths it is unlikely that any place is even close to a herd immunity threshold

That depends. Have you read the analysis by one of the authors of the study rather than the free-market libertarian news source that misinterprets it?https://twitter.com/profshanecrotty/status/1309170528889049089?s=19 …

I've read that article. It is both interesting and completely unrelated to the herd immunity argument in every way. No one is arguing that t-cells do not play a role in COVID-19 immunity, but as the AUTHOR OF THE STUDY YOU'RE CITING says, it means nothing for herd immunity

he actually says "Potential for cross-reactive immunity In one study, SARS-CoV-2-reactive CD4+ T cells were also identified in about 40 to 60% of unexposed individuals, suggesting cross-reactive T cell recognition between circulating ‘‘common cold’’ coronaviruses and SARS-CoV-2"

Prof. Shane Crotty @profshanecrotty7) Even IF such a pre-existing T cell immunity exists, those people are still susceptible to infection. COVID-19 disease severity for them would be less bad. Consistent with statements of CDC director Redfield and Fauci that 90% of Americans are still susceptible to infection.Show this thread1 reply 0 retweets 2 likes -

That thread is literally misinformation Prof Crotty (THE AUTHOR OF THE STUDY) again here:https://twitter.com/profshanecrotty/status/1293344524731691008?s=20 …

"even if our most optimistic speculations about crossreactive T cell memory were found to be correct, it would mean that just as many people would get infected with SARS-CoV-2" ~Prof Crotty

Another question - you're relying rather heavily on Prof Crotty's papers to make this erroneous argument. Have you read them?
