INFECTION
Neutralizing antibody titers against Omicron BA.4/BA.5 and ancestral SARS-CoV-2 (a) and geometric fold-rises from baseline levels (b) were assessed in participants without previous infection grouped by quartiles of dosing intervals between the first booster dose of mRNA-1273 and second booster doses of mRNA-1273 and mRNA-1273.222 post boost within each booster vaccine group at day 29. 95% CIs were calculated based on the t-distribution of the log-transformed values for GM value, then back-transformed to the original scale for presentation. Quartiles 1, 2, 3 and 4 represent quartiles indicated s in panel a for mRNA-1273 and mRNA-1273.222.
