  Purpose

The purpose of this study is to assess the humoral immune response and safety of the parenteral formulation of the 2010/2011-season virosomal subunit influenza vaccine Inflexal V using two different HA antigen suppliers (AdImmune and CSL), in groups of young and elderly adults, using the EMA (European Medicines Agency) regulation as a guideline.

Primary Outcome Measures:
  • Immunogenicity - Geometric Mean Titer Fold Increase From Baseline [ Time Frame: 3 weeks after vaccination (Day 22 ± 2 days) ] [ Designated as safety issue: No ]
    The primary endpoints were the immunogenicity parameters for HA assessed via hemagglutinin inhibition method (HI). These parameters were analyzed according to the EMA "Note for guidance on harmonisation of requirements for influenza vaccines," 1997 and they were the following: 1. Seroprotection rate, defined as proportion of subjects with HI antibody titer ≥1:40, 2. Seroconversion rate, defined as proportion of subjects with ≥4-fold increase in HI antibody titer and with a titer of ≥1:40, 3. GMT of HI antibodies and fold-increase in GMT

  • Immunogenicity - Seroprotection Rate [ Time Frame: 3 weeks after vaccination (Day 22 ± 2 days) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Number of Participants With Local and Systemic Adverse Events [ Time Frame: Baseline (Day 1) and 3 weeks after vaccination (Day 22 ± 2 days) ] [ Designated as safety issue: Yes ]

    Solicited local and systemic AEs, Unsolicited AEs, Tolerability and acceptability

    Unsolicited AEs were collected from baseline (Day 1) to 3 weeks after vaccination (Day 22 ± 2 days).

    Solicited local and systemic AEs were collected by subjects diary from Day 1 (day of vaccination) to Day 4

Detailed Description:

The objectives of this study are to evaluate the humoral immunogenicity and safety of the parenteral formulation of the 2010/2011-season influenza vaccine, Inflexal V, using HA antigen obtained from 2 different production facilities, and to compare the immunogenicity of both formulations to pre-defined EMA criteria for the annual relicensing of seasonal influenza vaccines. The evaluation will be done in young adults and elderly.
