Adjusted antibody GMC ratios between the Clin and the Com groups for the 10 vaccine pneumococcal serotypes and protein D at one month post-primary vaccination (primary ATP immunogenicity cohort). Clin = group of infants from Malaysia and Singapore who received the Phase III Clinical lot of PHiD-CV in the primary vaccination phase. Com = group of infants from Malaysia and Singapore who received the Commercial lot of PHiD-CV in the primary vaccination phase. Adjusted antibody GMC ratio = ratio of the geometric mean concentration at one month post-primary vaccination adjusted for country (pooled variance; Clin over Com group). PD = protein D. 95% CI = 95% confidence intervals (represented by the error bars). *Immunological non-inferiority was demonstrated if the upper limit of the 95% confidence interval of the adjusted antibody GMC ratio (Clin over Com) was below 2.0.
