Arms and Interventions

Intervention / Treatment
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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
21 days post-vaccination

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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).
3 days, respectively 21 days post-vaccination
