If prior CoV infections produce cross-reacting antibodies with SARS CoV 2, then how do we know those "false" antibodies are not to some degree protective?

WE DON'T.

A paper is being published in Cell that claims that 34% of healthy non-COVID people carry memory T-cells that transform in the presence of SARS Co V 2 antigens.

Now, this is not a clinical paper. It's published by in vitro cell nerds in a pure science journal.

But if it's right, it's great news because it may explain some of the observed facts, like low risk of household transmission with wide confidence intervals (for example).

Lots of hot stuff beginning to appear, as the virus and the disease it causes come into sharper focus.

I asked about how this could be a possible reality.

A couple of knowledgeable/nice freepers said that we could have the antibodies from our previous Corona infections, that were so minor we didn’t notice them. Or they came from our ancestral DNA.

Of course, that may have changed this week.
