  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.

Condition Intervention Phase
Influenza Biological: Virosomal influenza vaccine (AdImmune HA Antigen) Biological: Virosomal influenza vaccine (CSL HA Antigen) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Prevention
Official Title: Randomized, Parallel-group, Double-blind, Single-center Phase III Study to Assess the Immunogenicity and Safety of the 2011/2012-season Influenza Vaccine Formulated With HA Antigen From Two Suppliers, in Elderly and Young Adult Subjects Using the Current EMA Regulations as Guideline

Primary Outcome Measures:
  • Geometric Mean Titer [ Time Frame: 3 weeks after vaccination (Day 22 ± 2 days) ]
    GMT of HI antibodies and fold-increase in GMT (The primary endpoints are 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)

  • Seroprotection [ Time Frame: 3 weeks after vaccination (Day 22 ± 2 days) ]
    Seroprotection rate, defined as proportion of subjects with HI antibody titer ≥1:40 (The primary endpoints are 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)

  • Seroconversion [ Time Frame: 3 weeks after vaccination (Day 22 ± 2 days) ]
    Seroconversion rate, defined as proportion of subjects with ≥4-fold increase in HI antibody titer and with a titer of ≥1:40 (The primary endpoints are 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)


Secondary Outcome Measures:
  • Number of Participants With Local and Systemic Adverse Events, as a Measure of Safety and Tolerability [ Time Frame: Baseline (Day 1) and 3 weeks after vaccination (Day 22 ± 2 days) ]

    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
