Inclusion criteria
Inclusion criteria: All subjects must satisfy 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. • Written informed consent obtained from the subject. • Free of an acute aggravation of the health status as established by medical history and clinical examination before entering into the study. Elderly adults: • A man or woman 65 year of age or older at the time of the first vaccination. Young adults: • Man or woman between the ages of 18 and 40 years, inclusive. • If the subject is female, she must be of non-childbearing potential, i.e. have a current tubal ligation, hysterectomy, ovariectomy or be post-menopausal, or if she is of childbearing potential, she must practice adequate contraception for 30 days prior to vaccination, have a negative pregnancy test and continue such precautions for 2 months after completion of the vaccination series. Adequate contraception is defined as a contraceptive method with failure rate of less than 1% per year when used consistently and correctly (when applicable, as mentioned in the product label) for example abstinence, combined or progestogen oral contraceptives, injectable progestogen, implants of levonorgestrel, oestrogenic vaginal ring, percutaneous contraceptive patches or intrauterine device or intrauterine system, vasectomy with documented azoospermia of the sole male partner or double barrier method (condom or occlusive cap plus spermicidal agent). For azoospermia, “documented” refers to the laboratory report of azoospermia, required for acceptable documentation of successful vasectomy in the subject’s male partner. Post-menopause: Menopause is the age associated with complete cessation of menstrual cycles, menses, and implies the loss of reproductive potential by ovarian failure. A practical definition accepts menopause after 1 year without menses with an appropriate clinical profile at the appropriate age e.g. > 45 years. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes 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
Exclusion criteria
Exclusion criteria: • Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days prior to vaccination, 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 4 after vaccination and of an influenza vaccine other than the study vaccines up to Visit 4. • Vaccination against influenza since February 2008 with a seasonal influenza vaccine. • Previous vaccination in the last three years with an investigational adjuvanted vaccine candidate seasonal or pandemic influenza vaccine. • Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose (For corticosteroids, this will mean prednisone, or equivalent, >/= 0.5 mg/kg/day. 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 hypersensivity to a previous dose of influenza vaccine. • History of allergy or reactions likely to be exacerbated by any component of the vaccine(s) including egg or chicken protein. • Acute (active) clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by clinical evaluation (medical history and medical history directed physical examination) or pre-existing laboratory screening tests. • Acute disease at the time of enrolment. (Acute disease is defined as the presence of a moderate or severe illness with or without fever. All vaccines can be administered to persons with a minor illness such as diarrhoea, mild upper respiratory infection with or without low-grade febrile illness, i.e. Oral temperature <37.5°C [99.5 °F]). • Administration of immunoglobulins and/or any blood products within the three months preceding the first administration of the study vaccine or planned administration during the study. • Any medical conditions in which intramuscular injections are contraindicated. • Pregnant or lactating female. • Female of childbearing age planning to become pregnant or planning to discontinue contraceptive precautions. • Any medical condition that in the opinion of the investigator precludes the collection of blood volumes as required by the protocol.

| Main Objective: •To demonstrate, in subjects aged 65 years and older, that the frequency of influenza-specific CD4 T-cells per 10^6 CD4+ T-cells identified after in vitro stimulation with pooled vaccine strains as producing at least two different markers (CD40L, IL-2, TNF-alpha, IFN-gamma) induced by the FLU NG vaccine is superior to the one induced by Fluarix at Day 21 after vaccination. ;Secondary Objective: •To compare the CMI response, in terms of frequency of influenza-specific CD4 T-cells per 10^6 CD4+ T-cells identified after in vitro stimulation with pooled vaccine strains as producing at least two different markers (CD40L, IL-2, TNF-alpha, IFN-gamma), induced by the FLU NG vaccine in subjects aged 65 years or older with the one induced by Fluarix in subjects aged 18-40 years at Day 21 after vaccination. •To evaluate the CMI response in terms of frequency of influenza-specific CD4+ T-lymphocytes per 10^6 CD4+ T-cells 21, 42 and 180 days after vaccination for each vaccine strain separately and for pooled vaccine strains in each vaccine group. • To assess the humoral immunogenicity of FLU NG vaccine and Fluarix 21, 42 and 180 days following vaccination in each vaccine group. • To assess the reactogenicity and safety during the entire study period in each vaccine group. ;Primary end point(s): • The frequency of influenza-specific CD4 T-cells per 10^6 CD4+ T-cells identified after in vitro stimulation with pooled vaccine strains as producing at least two different markers (CD40L, IL-2, TNF-alpha, IFN-gamma) in the Flu NG and Flu Eld vaccine groups at Day 21 after vaccination. | — |
