Arm Intervention/treatment
Experimental: Elderly
Elderly subjects aged over 60 years
 Biological: Inflexal V

Inflexal V influenza vaccine, formulated for the WHO requirements of the 2009-2010 season, containing per 0.5 mL dose:

  • 15 µg hemagglutinin (HA) antigen of A/Brisbane/59/2007 (H1N1)-like virus
  • 15 µg HA antigen of A/Brisbane/10/2007 (H3N2)-like virus
  • 15 µg HA antigen of B/Brisbane/60/2008-like virus

Dose: intramuscular administration (M. deltoides) of a single dose of 0.5 mL on Day 1
Experimental: Adults
Adults from 18 to 60 years old inclusive
 Biological: Inflexal V

Inflexal V influenza vaccine, formulated for the WHO requirements of the 2009-2010 season, containing per 0.5 mL dose:

  • 15 µg hemagglutinin (HA) antigen of A/Brisbane/59/2007 (H1N1)-like virus
  • 15 µg HA antigen of A/Brisbane/10/2007 (H3N2)-like virus

Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Seroconversion [ Time Frame: Day 22 ± 2 days ]
    Seroconversion rate was defined as the number of subjects with ≥4-fold increase in haemagglutination inhibition (HI) antibody titer and with a titer of ≥1:40

  2. Seroprotection [ Time Frame: Day 22 ± 2 days ]
    Seroprotection rate, defined as the number of subjects with HI antibody titer ≥1:40

  3. Fold Increase in Geometric Mean Titer (GMT) [ Time Frame: Day 22/Day 1 ]
    GMT-fold increase - calculated as the GMT on Day 22 divided by the baseline GMT value


Secondary Outcome Measures :
  1. Safety: Numbers of Subjects Reporting Solicited Local Adverse Events [ Time Frame: Days 1 to 4 inclusive, and Day 22 ]
    Safety assessments are made by the investigator at baseline and on Day 22 as well as by the subjects themselves (in a Subject Diary) for the 4-day period immediately following vaccination

  2. Numbers of Subjects Reporting Solicited Systemic Adverse Events [ Time Frame: Days 1 to 4 inclusive, and Day 22 ]
    Safety assessments are made by the investigator at baseline and on Day 22 as well as by the subjects themselves (in a Subject Diary) for the 4-day period immediately following vaccination
