Outcomes

Primary Outcomes

Hemagglutination Inhibition (HI) Antibody Titers Against A/California/7/2009 H1N1 Vaccine Strain.

Time Frame: 21 days after the second dose of the unadjuvanted formulation of Arepanrix vaccine (at Day 42)

The A/California vaccine virus-homologous antibody response was measured in subjects having received Flulaval vaccine co-administered with the first dose of the unadjuvanted formulation of Arepanrix vaccine, and in subjects having received two doses of the unadjuvanted formulation of Arepanrix vaccine alone. Titers were expressed as geometric mean antibody titers (GMTs).
