again, this says absolutely *nothing* about lasting *immune memory* to #SARSCoV2. if you have memory T cells spin up immediately upon a second infection & cause existing B cells to generate strong nAbs within a day or so of infection, that still indicates strong protection. https://twitter.com/ProfPCDoherty/status/1275184803558514688

if #COVIDー19 just results in a mild case of the sniffles *at worst* for anyone that has had it, then how is this different from complete immunity?

a good thread outlining all the flaws present in these "immunity to #SARSCoV2 is short-lived!!!" papers: https://twitter.com/K_G_Andersen/status/1274015119828086786

but perhaps the most important take-home from it is, if immunity were *really* that short-lived, we would've seen evidence of re-infections by now.

and we have not.

how long immunity lasts is an open question, & there are still *many* unknowns. but it's def. >3 months at least.
