At least the abstract says something different:
> Nevertheless, rare but recurring RBD-specific antibodies with potent antiviral activity were found in all individuals tested, suggesting that a vaccine designed to elicit such antibodies could be broadly effective.
Very low levels, but still produced. (Note that I still have to dig through the paper.)
- gizmo 6y agoMy understanding is that those RBD-specific antibodies are not necessarily produced as a response to covid19, but I could be mistaken. In addition: > Plasmas collected an average of 39 days after the onset of symptoms had variable half-maximal neutralizing titers ranging from undetectable in 33% to below 1:1000 in 79% Of course this is only a single study and more research is needed, but I notice people draw way too strong conclusions from studies that show low seropositivity prevalence.
- lbeltrame 6y agoIt looks like another preprint found antibodies in the airways mucosa instead of blood. That would perhaps explain why some were undetectable.
