Study to Evaluate an Influenza Vaccine Candidate

A Study to Demonstrate the Non-Inferiority of Influenza Vaccine Candidate, Compared With Fluarix™ Administered Intramuscularly in Elderly Aged 60 Years Old and Above

The purpose of this study is to evaluate the immune response and safety of influenza vaccine candidate with or without adjuvant compared to Fluarix™ administered intramuscularly in elderly aged 60 years old and above.

Subjects will be randomized into 3 groups and will be followed for 6 months with 4 scheduled contacts per subjects. The immune response will be evaluated at days 0, 21 and 180 after vaccination. The safety evaluation will involve follow-up of solicited local and general signs and symptoms, unsolicited adverse events and serious adverse events.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
