Brief summary: This study is designed to generate clinical data as outlined in the Note for Guidance on harmonization requirements for influenza vaccine marketing authorization by the European Medicines Agency.

The objectives of the trial are:

* To determine immunogenicity, of the inactivated, split-virion influenza vaccine Northern Hemisphere (NH) 2007-2008 formulation in terms of the requirements of the Committee for Human Medicinal Products (CHMP) Note for Guidance (NfG) CPMP/BWP/214/96.
* To describe the safety of the inactivated, split-virion influenza vaccine, NH 2007-2008 formulation.

* Provision of a signed informed consent
* Able to attend all scheduled visits and comply with all trial procedures
* For a woman of child-bearing potential: avoid becoming pregnant (use of an effective method of contraception or abstinence) for at least 4 weeks prior to vaccination, until at least 4 weeks after vaccination

Exclusion Criteria :

* For a woman of child-bearing potential, known pregnancy or positive urine pregnancy test at Visit 1

* Known 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 any of the same substances
* Chronic illness at a stage that could interfere with trial conduct or completion, in the opinion of the Investigator
* Current alcohol abuse or drug addiction that may interfere with the subject's ability to comply with trial procedures
* Receipt of blood or blood-derived products in the past 3 months, that might interfere with the assessment of immune response
* Receipt of any vaccine in the 4 weeks preceding the trial vaccination
* Planned receipt of any vaccine in the 3 weeks following the trial vaccination
* Previous vaccination against influenza in the previous 6 months
* Thrombocytopenia, bleeding disorder or anticoagulants in the 3 weeks preceding inclusion contraindicating intramuscular vaccination
