Study Endpoints

Primary Endpoints

Geometric Mean of Haemagglutination Inhibiting (HI) Antibodies Titers Against the Three Strains.
At Day 0 and 28 after last vaccine dose.

The three strains assessed were A/Brisbane/59/2007 (H1N1), A/Uruguay/716/2007 (H3N2) and B/Brisbane/60/2008. Titers were expressed as geometric mean antibody titers (GMTs).

Number of Seroconverted Subjects for HI Antibodies Against the Three Strains.
At Day 28 after last vaccine dose.

The three strains assessed were A/Brisbane/59/2007 (H1N1), A/Uruguay/716/2007 (H3N2) and B/Brisbane/60/2008. Seroconversion was defined as the percentage of vaccinees that had either a pre-vaccination (Day 0) titer \< 1:10 and a post-vaccination titer ≥ 1:40 or a pre-vaccination titer ≥ 1:10 and at least a four-fold increase in post-vaccination titer.
