Annual Study to Investigate Inactivated Subunit Influenza Vaccine Due to New Virus Strains for the 2012/2013 Season

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01633749
Recruitment Status : Completed

Brief Summary:
Annual study to investigate influenza vaccine (flu vaccine) developed for the 2012/2013 season for the prevention of influenza infection. The immunizing effect is being investigated, as well as its tolerability and safety.

Condition or disease Intervention/treatment Phase
Prophylaxis of Influenza Biological: Trivalent influenza subunit vaccine Influvac Phase 3

Detailed Description:
An open, baseline-controlled study in two age groups: adults and elderly. The subjects will be screened within 14 days prior to or at Visit 1 (Day 1). At Visit 1 (Day 1) subjects will be vaccinated after blood sampling for baseline serum antihemagglutinin antibody titration. Subjects will be asked to record local and systemic reactions daily on a diary at home for 72 hours after vaccination. One week later (Visit 2, Day 8) the subjects will return to the study site to hand in the diary and for the assessment of safety and tolerability (reactogenicity and overall inconvenience). Three weeks after vaccination (Visit 3, Day 22) the subjects will return to the study site for blood sampling to assess immunogenicity and for the assessment of safety and tolerability.
