Extended Data Fig. 2: Plasma antibody kinetics post CoronaVac vaccination.

a, Vaccinated participants plasma reactivity to RBD measured by ELISA. b, Plasma neutralization titers measured at baseline, previously to BNT162b2 booster shot against ancestral virus, Delta and Omicron variants. Regression lines are shown over time as days post 2 CoronaVac dose vaccination, as purple (ancestral), dark green (Delta) and light green (Omicron). Lines indicates cross-sectional averages from each group, with shading representing 95% CI and colored accordingly. Each dot represents a single individual. n = 101 (Ancestral); n = 101 (Delta); n = 80 (Omicron).
