@LongDesertTrain @EricTopol Their IgG assay is worse than their total (Ig) assay on seroreversion. Total is pretty good, outside of the first few weeks post-infection. Usual caveats apply (ex: after a single infection only, not after re-infection nor post

@WvuDuke @AaronBlake You advocate antibody testing. I agree an established serosurveillance programme is ideal. But its very much an imperfect science and I know the FDA had big issues with reliability. And a recent study found significant issues in detect

Agree. The strength of the immune response in COVID-19 appears to be proportional to symptom intensity so those who had asymptomatic infection the first time around may be susceptible with time...specially to new variants.
