Relationship between the Hamming distance for spike from SARS-CoV-2 variants causing COVID-19 cases (vs spike from the mRNA-1273 vaccine SARS-CoV-2 strain) in (A) the placebo or (B) vaccine arm and binding antibody level (assessed by the 10-plex assay, see Supplementary Figure 4) at disease day 29. Each large dot is a mean value over all participants, each faded dot/faded line is from an individual participant. Abbreviations: AUC, area under the receiver operating curve; COVID-19, coronavirus disease 2019; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
