Primary Outcome Measures:
  • 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) [ Time Frame: 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:
  • To evaluate the safety of the administration of a single intramuscular (IM) injection of FLUAD® vaccine (formulation 2007/2008) in elderly subjects (≥ 65 years). [ Time Frame: 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).

Arms Assigned Interventions
Experimental: Arm 1 Biological: Surface Antigen, Inactivated, Adjuvanted Influenza Vaccine, Formulation 2007-2008

A single 0.5mL dose of Novartis adjuvanted subunit influenza vaccine, Fluad contained 45μg of viral hemagglutinin, composed of 15μg of the three influenza antigens:

  • A(H1N1) strain: IVR-145 (Solomon Island/3/2006 - like strain)
  • A(H3N2) strain: NYMC X-161B (A/Wisconsin/67/2005-like strain)
  • B strain: (B/Malaysia/2506/2004-like strain) in accordance with the recommendations of the World Health Organization, the EU and the national Regulatory Agencies for the 2007/2008 season.

The vaccine is a milky liquid, and was packaged in ready to use, single dose syringes.

A single dose of FLUAD vaccine was administered intramuscularly, preferably in the deltoid muscle of the non dominant arm.
