Seroconversion rate (SCR) was defined as the proportion of subjects who had either a pre-vaccination reciprocal HI titer below (\<) 10 and a post-vaccination reciprocal titre greater than or equal to (≥) 40, or a pre-vaccination reciprocal HI titer ≥ 10 and at least a 4-fold increase in post vaccination reciprocal titer against the vaccine virus. The Flu strain assessed was A/California/7/2009 (H1N1)v-like virus (Flu A/CAL/7/09), following the Committee for Medicinal Products for Human Use (CHMP) and the Center for Biologics Evaluation and Research (CBER) guidance. The CBER criterion was fulfilled if the lower 95% confidence interval (CI) for SCR was (\>) 40%. The CHMP criterion was fulfilled if the point estimate for SCR was \> 40%.
A seroprotected subject was defined as a vaccinated subject with a serum HI titer greater than or equal to (≥) 1:40, that usually is accepted as indicating protection. The Flu strain assessed was Flu A/CAL/7/09, following the CHMP and the CBER guidance. The CBER criterion was fulfilled if the lower limit of the 95% CI for seroprotection (SPR) was \> 70%. The CHMP criterion was fulfilled if the post-vaccination point estimate for SPR was \> 70%.
GMFR, also called seroconversion factor (SCF), was defined as the fold increase in serum HI geometric mean titers (GMTs) post-vaccination compared to pre-vaccination. The Flu strain assessed was Flu A/CAL/7/09, following the CHMP and the CBER guidance. The CHMP criterion was fulfilled if the point estimate for GMFR was \> 2.5.
