Primary Outcome Measures
NameTimeMethod
Antibody response to each influenza vaccine antigen as measured by Single Radial Hemolysis in elderly subjects (≥65y) in compliance with the requirements of the current EU recommendations for a new formulation of a licensed flu vaccine (CPMP/BWP/214/96)21 days post-vaccination

The measures of immunogenicity for each antigen are:

* the geometric mean area (GMA) on Day 0 and Day 21

* the Day 21/Day 0 geometric mean area ratio (GMR)

* the percentage of subjects achieving seroconversion1 or significant increase in antibody titer2

* the percentage of subjects achieving an SRH area ≥ 25 mm2 on Day 0 and Day 21

1. Seroconversion is defined as negative prevaccination serum/postvaccination serum area ≥ 25 mm2.

2. Significant increase in antibody titer is defined as at least a 50% increase in area.

Secondary Outcome Measures
NameTimeMethod
To evaluate the safety of the administration of a single intramuscular (IM) injection of FLUAD® vaccine (formulation 2007/2008) in elderly subjects (≥ 65 years).3 days, respectively 21 days post-vaccination

Number and percentage of subjects with at least one local reaction between Day 0 and Day 3 after vaccine injection.

Number and percentage of subjects with at least one systemic reaction between Day 0 and Day 3 after vaccine injection.

Number and percentage of subjects with at least one adverse event between Day 0 and the study termination visit (Day 21, window: 20-24).
