A study surveying levels of neutralizing antibodies (NAbs) to the SARS-CoV-2 spike protein in the plasma of 175 patients who had recovered from COVID-19 in one health center in Shanghai, China, published on ▻https://www.medrxiv.org/content/10.1101/2020.03.30.20047365v1, shed some light on the development of natural immunity to the virus. These results have not yet been peer-reviewed. Though patients in this study were classified as mild cases, antibody levels correlated positively with C-reactive protein and inversely with lymphocyte counts (NAb levels also tended to be higher in older subjects). A troublesome finding of the study was that approximately 30% of recovered patients showed low NAb titers, including 10 patients with NAbs below the detection limit of the assay.
