I can't find it at the moment, but there was a recent brief study published by Chinese researchers that showed having COVID-19 seems to generate far fewer antibodies. To the extent that titer results imply people might not be immune to reinfection in the near future, and serum treatment might not be as effective as with other diseases.
Would be good to know which population(s) they studied, and if it's true regardless of the severity of the illness.
It could be that those with severe illness are a subpopulation with poor antibody titers, and that's why the disease was able to progress. And that those with milder illness fought it off because of higher antibody titers. This in turn could be due to state of health, or genetic variation in the antibody generating system.
Need more data! Always!
