Some new results from , and () on post-infection RBD seroconversion and reversion and neutralising antibodies out to 75 days post symptom onset.
We found that IgG antibodies binding to RBD and pseudoneutralizing antibodies had little evidence of decay in measurements up to 75 days. As potentially expected, we found IgM and IgA antibodies binding to RBD decayed at approximately 50 days.
