Figure 3.
Pseudovirus neutralization titers against prototype SARS-CoV-2 and multiple Omicron sublineages for sera collected 14 days after the booster vaccination. The sera were from individuals vaccinated with the fourth dose of BV-01-B5, V-01D-351, V-01, or CoronaVac after three doses of inactivated vaccine. For all panels, the values above the symbols denote the geometric mean titer, the numbers in parentheses denote the seroconversion rates (a negative baseline titer (<5) to positive conversion (≥5), and at least four-fold increases from a positive baseline titer), and bars denote the geometric mean titer (95% CI). The numbers over the upper dotted line denote the geometric mean ratio (compared to CoronaVac) against multiple Omicron sublineages. The lower dotted line denotes the limit of detection (LOD = 10).
