Study Endpoints

Primary Endpoints

Number of Subjects With Haemagglutination-inhibition (HI) Antibody Concentrations Above the Cut-off Value
At Day 0

The seropositivity cut-off value of the assay was equal to or above (≥) 1:10 in the sera of subjects seronegative before vaccination. The flu strain assessed was A/California/7/2009 (H1N1)v-like (Flu A/CAL/7/09).

Number of Subjects With HI Antibody Concentrations Above the Cut-off Value
At Day 42

The seropositivity cut-off value of the assay was ≥ 1:10 in the sera of subjects seronegative before vaccination. The flu strain assesssed was Flu A/CAL/7/09.

Titers for Serum HI Antibodies
At Day 0

Antibody titers were presented as geometric mean titers (GMTs). The reference seropositivity cut-off value was ≥ 1:10. The flu strain assessed was Flu A/CAL/7/09.

Number of Seroconverted (SCR) Subjects in Terms of HI Antibodies
At Day 42

A seroconverted subject was defined as: For initially seronegative subjects \[antibody titer below (\<) 1:10 prior to vaccination\], antibody titer ≥ 1:40 after vaccination; For initially seropositive subjects (antibody titer ≥ 1:10 prior to vaccination), at least a 4-fold increase in post-vaccination titer. The flu strain assessed was Flu A/CAL/7/09.

Number of Seroprotected (SPR) Subjects in Terms of HI Antibodies
At Day 42

Seroprotection was defined as the percentage of subjects with a serum HI titer ≥ 1:40, that usually is accepted as indicating protection. The flu strain assessed was Flu A/CAL/7/09.

Seroconversion Factor (SCF) for HI Antibody Titers
At Day 42

Seroconversion factor was defined as the fold increase in serum HI GMTs post-vaccination compared to pre-vaccination. The flu strain assessed was Flu A/CAL/7/09.

Number of Seropositive Subjects for H1N1 Haemagglutination Inhibition (HI) Antibodies
At Day 0

Seropositivity was defined as H1N1 HI antibody titers greater than or equal to (≥) 1:10. The strain assessed was Flu A/California/7/2009 (H1N1).

Titers for H1N1 Haemagglutination Inhibition (HI) Antibodies
At Day 0

Antibody titers are presented as geometric mean titers (GMTs), with a reference seropositivity cut-off value greater than or equal to (≥) 1:10. The strain assessed was Flu A/California/7/2009 (H1N1).

Number of Seroconverted Subjects in Terms of H1N1 Haemagglutination Inhibition (HI) Antibodies
At Day 42

Seroconversion (SCR) was defined as the percentage of vaccinees that have either a pre-vaccination titer \< 1:10 and a post-vaccination titer ≥ 1:40, or a pre-vaccination titer ≥ 1:10 and at least a 4-fold increase in post-vaccination titer. The strain assessed was Flu A/California/7/2009 (H1N1).

Number of Seroprotected Subjects for H1N1 Haemagglutination Inhibition (HI) Antibodies
At Day 42

Seroprotection (SPR) was defined as the percentage of vaccinees with a serum HI titer ≥ 1:40 that usually is accepted as indicating protection. The strain assessed was Flu A/California/7/2009 (H1N1).

Seroconversion Factor (SCF) for H1N1 Haemagglutination Inhibition (HI) Antibody Titers
At Day 42

Seroconversion factor was defined as the fold increase in serum HI geometric mean titers (GMTs) post-vaccination compared to pre-vaccination. The strain assessed was Flu A/California/7/2009 (H1N1).
