K. Thanks for "refuting" a comment where I said "total antibody-based immunity will last a few years, based on our experience with SARS-CoV-1" with evidence that antibodies are gone several years later. :P
No no, thank YOU for "refuting" my "refutation"! I do stand corrected, I did not internalize your "total antibody-based immunity will last a few years" sentance, and was focused on the following "memory B cell / T cell based immunity is likely lifelong".
Your study leans against the memory B cell part, but found strong memory T cell response, so...
