Arms and Interventions

Arm	Intervention/treatment
Experimental: Group A; Adults from 18 to 60 years old inclusive	Biological: Inflexal V; Inflexal V influenza vaccine, formulated for the WHO requirements ofr the 2008-2009 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/Florida/4/2006-like virus Dose: intramuscular administration (M. deltoideus) of a single dose of 0.5 mL on Day 1
Experimental: Group B; Elderly subjects aged over 60 years	Biological: Inflexal V; Inflexal V influenza vaccine, formulated for the WHO requirements ofr the 2008-2009 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/Florida/4/2006-like virus Dose: intramuscular administration (M. deltoideus) of a single dose of 0.5 mL on Day 1

Outcome Measures

Primary Outcome Measures :

1. Seroconversion [ Time Frame: Day 22 ± 2 days ]
   Seroconversion rate was defined as the proportion 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 proportion 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: Incidence of 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. Incidence of 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
