unscheduled visit up to 1 month after Dose 2 were included in t he analysis. 
a.     Protocol-specified timing for blood sample collection. 
b.     n = Number of subjects with  valid and determinate assay results for the specified assay at the given dose/sampling time  point. 
c.     GMTs and 2-sided 95% CIs were calculated by exponentiati ng the mean logarithm of the titers and the corresponding CIs ( based on the Student t 
distribution). Assay results below the LLOQ were set to 0.5 × L LOQ. 
d.     GMRs and 2-sided 95% CIs were calculated by exponentiati ng the mean difference of the l ogarithms of the titers (Group 1  [12-15 years] – Group 2 [16-25 
years]) and the corresponding CI (based on the Student t dis tribution). 
e.     Noninferiority is declared  if the lower bound of the 2-s ided 95% CI for the GMR is greater than 0.67.
