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: Subjects are not to be enrolled into the study if at least one of the following criteria is fulfilled: 1. They have any serious chronic or acute disease (in the judgment of the investigator) including but not limited to: a. Cancer, except for localized skin cancer b. Advanced congestive heart failure c. Chronic obstructive pulmonary disease (COPD) d. Autoimmune disease (including rheumatoid arthritis) e. Acute or progressive hepatic disease f. Acute or progressive renal disease g. Severe neurological or psychiatric disorder h. Severe Asthma 2. History of any anaphylactic reaction and/or serious allergic reaction following a vaccination, a proven hypersensitivity to any component of the study vaccine (e.g., to ovalbumin, chicken protein, chicken feathers, influenza viral protein neomycin or polymyxin). 3. Known or suspected (or have a high risk of developing) impairment/alteration of immune function (excluding that normally associated with advanced age) resulting for example from: a. receipt of immunosuppressive therapy (any parental or oral cortical steroid or cancer chemotherapy/radiotherapy) within the past 60 days and for the full length of the study; b. Receipt of immunostimulants, c. Receipt of parenteral immunoglobulin preparation, blood products, and/or plasma derivatives within the past 3 months and for the full length of the study, d. Suspected or known HIV infection or HIV-related disease. 4. Known or suspected history of drug or alcohol abuse. 5. They have a bleeding diathesis or conditions associated with prolonged bleeding time that in the investigator’s opinion would interfere with the safety of the subject; 6. Women who are pregnant or woman of childbearing potential unwilling to practice acceptable contraception for the duration of the study (21 days). Females who are pregnant or nursing (breastfeeding) mothers or females of childbearing age who do not plan to use acceptable birth control measures, for the duration of the study. Adequate contraception is defined as hormonal (oral, injection, transdermal patch, implant, cervical ring), barrier (condom or diaphragm), intrauterine device (IUD) or monogamous relationship with vasectomized partner who has been vasectomized for 6 months or more prior to the subject’s study entry. 7. Influenza vaccination or laboratory confirmed influenza within the last 6 months and more than one influenza vaccination within the past 12 months 8. Within the past 4 weeks they have received: - another vaccine - any investigational agent; 9. Any acute or chronic infection requiring systemic antibiotic treatment or antiviral therapy within the last 7 days. 10. They have experienced fever (i.e., axillary temperature = 38°C) within the last 3 days 11. Simultaneous participation in another clinical study. 12. Any condition, which, in the opinion of the investigator, might prevent the subject from participation or interfere with the evaluation of the study objectives. 13. Severely obese with Body Mass Index (BMI) > 35 14. Site personnel involved in evaluation of safety and their immediate relatives are excluded from participation.

| Secondary Objective: To evaluate safety of a single IM (intramuscular) dose of the subunit influenza vaccine Fluvirin® in non-elderley adult and elderly subjects in compliance with the requirements of the current EU recommedations for clinical tirals related to yearly licensing of influenza vaccine (CPMP/BWP/214/96);Main Objective: To evaluate the antibody reponse to each influenza vaccine antigen, as measured by Haemagglutination Inhibition (HI) test at 21 days post-immunisation in non-elderley adult and elderely subjects in compliance with the requirements of the current EU recommedations for clinical trials related to yearly licensing of influenza vaccines (CPMP/BWP/214/96);Primary end point(s): The following serological assessments should be considered for each strain in non-elderly adult subjects, aged between 18 and 60 years, and at least one of the assessments should meet the indicated requirements: • The proportion of subjects achieving seroconversion or significant increase in anti-HA antibody titer should be > 40% • Mean geometric increase should be > 2.5 • The proportion of subjects achieving an HI titer = 40 or SRH area = 25 mm2 should be > 70% The following serological assessments should be considered for each strain in elderly subjects, aged over 60 years, and at least one of the assessments should meet the indicated requirements: • The proportion of subjects achieving seroconversion or significant increase in anti-HA antibody titer should be > 30% • Mean geometric increase should be > 2.0 • The proportion of subjects achieving an HI titer = 40 or SRH area = 25 mm2 should be > 60% Circulating anti-HA antibodies will be measured by HI assay just prior to vaccination (Day 0) and approximately 3 weeks after the vaccination (Day 21). For the purposes of calculation, any HI result < 10 (i.e. undetectable) will be expressed as 5. If an SRH assay is used, any negative SRH result will be expressed as 4 mm2.
