  1. Mean and 95% CI (within parentheses) of the vaccine efficacy estimates by baseline serostatus, serotype and age-group generated with imputation and significance of the statistical difference in vaccine efficacy between baseline seropositive and baseline seronegative subjects against each serotype in each age-group. The p-values were obtained using the Pearson’s chi-squared test. sero+ stands for seropositive; sero− stands for seronegative. Significant (<0.05) p-values and the corresponding estimates are in bold
