Fig. 2: GMTs of live virus nAb against Omicron BA.1, BA.5, and Delta.
From: Safety and immunogenicity of a tetravalent and bivalent SARS-CoV-2 protein booster vaccine in men
A The geometric mean titers (GMTs) of live virus neutralizing antibodies (nAb) against Omicron BA.1 at day 28 post-injection measured using 50% plaque reduction neutralization test (PRNT50). B The GMTs of nAb against Omicron BA.5 at day 28 post-injection. C The GMTs of nAb against Delta variant at day 28 post-injection. For (A–C), bars show the GMTs with 95% CIs at day 0 and day 28. Dots represent the values for individual participants. Centre of the error bars represents the GMT. Only those with available baseline and post-baseline data were included in BNT162B2 group (grey), SCTV01C group (blue) and SCTV01E group (red). GMR geometric mean ratio, LS GMR least square geometric mean ratio. Note: Subjects who were COVID-19 infected between Day 0 and Day 28 were excluded from analysis. Source data are provided as a Source Data file. *superiority; +non-inferiority.
