Estimated vaccine efficacy by serotype, serostatus and age group, against symptomatic disease and hospitalization. The solid line represents the mean of the posterior distribution, and the shaded area represents the 95%CrI of the posterior distribution (n = 20,000 samples). The dashed horizontal line marks 0 efficacy. Vaccine efficacy in multitypic individuals is shown in Supplementary Fig. 8. P, placebo arm; SN, seronegative; SP, seropositive; V, vaccine arm.
