  Similar to the other article I sited, "we were unable to evaluate immune memory in those with the extreme presentations, both asymptomatic and severe COVID-19" So unfortunately since I specifically and repeatedly referred to asymptomatic cases, which are relatively common in those under 30, it is not good enough. If I could edit my original post to <B>BOLD</B> asymptomatic even more, I would, since I highly doubt you're going to find many studies on that group.

      Thank you so much for a relevant article! At least it shows that in some/many asymptomatic cases there is an adaptive response. That makes me feel a bit better. However, from my very first post "vaccine immunity is more robust than asymptomatic infections"... and detectable antibodies is a far cry (orders of magnitude) from neutralizing antibody levels, which are not uncommon even 8 months out in healthy vaccinated youth.
