Study start date: June 1, 2010

Actual date on which the first participant was enrolled.

Influenza (flu) viruses change continuously, therefore also the parts of viruses used in influenza vaccines can vary from year to year. In Europe, manufacturers/marketing holders of these vaccines are required to be involved in ongoing clinical trials and to present the results to the competent authorities each year. The current study is a phase IIIa clinical trial with a commercially available vaccine (Influvac®) supplied in pre filled syringes. It is part of the ongoing clinical trial program for Influvac® and will be done to assess the immunogenicity and safety and tolerability of next season's trivalent influenza subunit vaccine in two groups of subjects in good health: subjects aged >= 18 and <= 60 years and subjects >= 61 years of age (elderly)
