Neutralizing antibody responses (IU/mL) in study subjects. (A) Neutralizing antibody response against the alpha, delta, and omicron variants between the three groups, the day before and 28 days after administration of the third dose of the mRNA vaccine. (B) Comparison of the antibody responses 28 days after administration of the third and the second doses of the vaccines. mRNA-1273/mRNA-1273 indicates a homologous mRNA-1273 vaccination schedule. Mann–Whitney U test was performed to compare the antibody responses between the groups. P values were indicated when a statistical significance was determined. Abbreviations: B.1.1.7, alpha; B.1.617.2, delta; B.1.1.529, omicron; NT50, neutralizing antibody responses.
