That’s not what you said above, and you have a history of misinterpreting what studies say anyway.
What I said above is that they don’t have antibodies. And they don’t. You’re confused about the difference between T cells and antibodies, which are produced by B cells.
Demonstrating that there are some cross-reactive T cells in a lab is not the same as showing that they have antibodies against the new virus. My history is that of explaining the study data in plain English to help people understand it and put it in context. Not twist it into some pre-selected narrative. If you’re confused about the study you referenced, you may be about others as well.
