- Informed consent form signed
- Able to attend all scheduled visits and to comply with all trial procedures
- For a woman of childbearing potential: a negative urine pregnancy test and documented use of an effective method of contraception or abstinence for at least four weeks pre vaccination and up until three weeks post-vaccination
Exclusion Criteria :
- Subject currently breast-feeding.
- Participation in another clinical trial investigating a vaccine, drug, medical device, or medical procedure in the 4 weeks preceding the trial vaccination.
- Planned participation in another clinical trial during the present trial period.
- Prior participation in the Phase I trial of FLU INTERPAN (PER.C6) vaccine (study GCE01).
- Congenital or history of acquired immunodeficiency, or immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months.
- Systemic corticosteroid therapy as except the use of topical or inhalant corticosteroids
- Systemic hypersensitivity to egg proteins, chicken proteins, or to any of the vaccine components, or history of a life-threatening reaction to the trial vaccine or a vaccine containing the same substances.
- Chronic illness at a stage that could interfere with trial conduct or completion (chronic illness may include, but is not limited to, cardiac, renal or auto-immune disorders, or diabetes).
- Receipt of blood or blood-derived products in the 3 months preceding vaccination.
- Receipt of any vaccination in the 4 weeks preceding vaccination, or planned receipt of any vaccination in the 4 weeks following the trial vaccination.
- History of influenza infection (confirmed either clinically, serologically or microbiologically) within the 6 months preceding vaccination.
- Previous vaccination against influenza (in the 6 months preceding the trial vaccination).
- Planned receipt of any other 2007-2008 influenza vaccine.
- Thrombocytopenia or bleeding disorder contraindicating intramuscular (IM) vaccination.
- Subject deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized without his/her consent.
- History of Guillain-Barré syndrome
- Current abuse of alcohol or drug addiction that may interfere with the subject's ability to comply with trial procedures

Summary of the Pre- and Post-Vaccination Geometric Mean Titers (GMTs) for Each of the Influenza Vaccine Antigens.
時間枠:Days 0 and 21 post-vaccination
|
Days 0 and 21 post-vaccination
|
|
|
Percentage of Participants With Seroprotection to Each of the Influenza Vaccine Antigen Before and Post-vaccination.
時間枠:Day 21 post-vaccination
|
Seroprotection was defined as a titer ≥ 40 1/dil, and determined in participants with a valid serology result for the particular Flu strain, including results reported as less than lower limit of quantitation (LLOQ)
|
Day 21 post-vaccination
|
|
Percentage of Participants Achieving Seroconversion or Significant Increase at Day 21 Following Vaccination With Influenza Vaccine.
時間枠:Day 21 post-vaccination
|
Seroconversion: For participants with a Day 0 pre-vaccination titer < 10 (1/dil), titer ≥ 40 (1/dil) on Day 21. Significant Increase: For participants with a Day 0 pre-vaccination titer ≥ 10 (1/dil), ≥ 4-fold increase of titer on Day 21. |
Day 21 post-vaccination
