All subjects must satisfy ALL the following criteria at study entry:
•Subjects who the investigator believes that they can and will comply with the requirements of the protocol (e.g., completion of the diary cards, return for follow-up visits) should be enrolled in the study. Specific attention should be given to the compliance potential of subjects with suspected or known drug or alcohol abuse.
•A man or woman 65 years of age or older at the time of vaccination.
•Written informed consent obtained from the subject.
•Free of an acute aggravation of the health status as established by clinical evaluation (medical history and medical history directed examination) before entering into the study.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) no
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range
The following criteria should be checked at the time of study entry. If ANY exclusion criterion applies, the subject must not be included in the study:
•Any confirmed or suspected (clinical diagnosis ‘flu’ in a medical history, or retrospective assessment by investigator) influenza illness within the last 6 months.
•Previous vaccination against influenza with any seasonal vaccine since December 2008.
•Planned administration of an influenza vaccine other than the study vaccines during the entire study period.
•Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the dose of study vaccine, or planned use during the study period.
•Administration of other licensed vaccines within 2 weeks (for inactivated vaccines) or 4 weeks (for live vaccines) prior to enrolment in this study. Planned administration of a vaccine not foreseen by the study protocol up to Visit 2.
•Administration of immunoglobulins and/or any blood products within the 3 months preceding the dose of study vaccine or planned administration during the study period.
•Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs within six months prior to the vaccine dose. For corticosteroids, this will mean prednisone >= 0.5 mg/kg/day, or equivalent. Inhaled and topical steroids are allowed.
•Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
•History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine(s) including egg and chicken protein, included history of hypersensitivity to a previous dose of influenza vaccine.
•Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.
•Acute disease and/or fever at the time of enrolment.
? Fever is defined as temperature >= 37.5°C on oral setting.
? Subjects with a minor illness (such as mild diarrhoea, mild upper respiratory infection) without fever may be enrolled at the discretion of the investigator.
•Any medical conditions in which IM injections are contraindicated.

Name Time Method Main Objective: To assess the immunological non-inferiority (in terms of Haemagluttination Inhibition (HI) antibody Geometric Mean Titers (GMT)) of an aged lot of the FLU NG vaccine 21 days after vaccination in elderly subjects aged >= 65 years old compared to a fresh lot of FLU NG vaccine.<br>;Secondary Objective: To assess the immunogenicity (seroconversion factor, seroconversion rate and seroprotection rate) of an aged lot and a fresh lot of FLU NG vaccine, 21 days after vaccination in subjects >= 65 years old.<br>To assess the safety and reactogenicity of an aged lot and a fresh lot of FLU NG vaccine in subjects >= 65 years old.<br>;Primary end point(s): •Humoral immune response in terms of HI antibodies<br>? Serum HI antibody titers, against the three vaccine strains, in each group at Day 0 and 21.<br>? GMTs of HI antibody titers at Day 0 and 21.<br>
