Figure 2.
Pseudovirus-neutralizing antibody titers against prototype SARS-CoV-2 (A) and Omicron BA.4/5 strain (B) at baseline and 7, 14, 28 days after BV-01-B5, V-01D-351, V-01 or CoronaVac booster following three doses of inactivated vaccine. The individual data in each group are denoted by different colors, and bars denote geometric mean titer (95% CI). The lower dotted line denotes the limit of detection (LOD = 10). ↑ denotes the geometric mean fold rises (GMFR) of neutralizing antibody at 7, 14 days after booster from the baseline.
