Brief Summary
The purpose of this study is to determine the immunogenicity, tolerability and dose-effect relationship of one 0.5 mL intramuscular (IM) injection of four FLUVAL AB-like trivalent influenza vaccines containing either 3.5μgHA, 6μgHA,9μgHA or 15μgHA of seasonal A/H1N1, A/H3N2 and B influenza antigens in adults and elderly people.

Outcome Measures
Primary Outcomes (1)
MEASURES OF IMMUNOGENICITY
The measures of immunogenicity, for all evaluable subjects by using HI test are: * the GMTs at Day 0, at Day 14 and at Day 21 as determined by HI; * the Day 14/Day 0, the Day 21/Day 0 and the Day 21/Day 14 geometric mean titer ratios (GMTRs) as determined by HI; * the percentage of subjects achieving seroconversion1 or significant increase in antibody titer2 at Day 14 an at Day 21, as determined by HI; * the percentage of subjects achieving a titer ≥40 at Day 0, at Day 14 and at Day 21 as determined by HI.
21-28 days following vaccination

Eligibility Criteria
You may qualify if:
- male and female adult volunteers aged 18 years or older,
- mentally competent,
- able to understand and comply with all study requirements,
- willing and able to give written informed consent prior to initiation of study procedures,
- in good health (as determined by clinical judgement of the investigator on the basis of medical history and existing medical condition) or are in stable medical condition. Subjects will not be excluded with known, adequately treated, clinically significant organ or systemic diseases (e.g. asthma or diabetes), such that, in the opinion of the investigator, the significance of the disease will not compromise the subject's participation in the study.
- Female subjects aged 18 to 60 years (i.e. participants of childbearing potential) with a negative result from the urine pregnancy test prior to vaccination who agrees to use an acceptable contraception method or abstinence throughout the trial and not become pregnant for the duration of the study.
You may not qualify if:
- Pregnancy, breast-feeding or positive urine pregnancy test at baseline prior to vaccination. Female subjects who are able to bear children but not willing to use an acceptable contraception method for the duration of the study.
- Hypersensitivity to eggs, chicken protein, thiomersal, formaldehyde, gentamycin, ciprofloxacin, neomycin or any other component of the vaccine;
- History of anaphylactic shock or neurological symptoms or signs following administration of any vaccine;
- History of Guillain-Barré syndrome;
- Serious disease, such as cancer, autoimmune disease, advanced arteriosclerotic disease, complicated diabetes mellitus, acute or progressive hepatic disease, acute or progressive renal disease, congestive heart failure;
- Immunosuppressive therapy within the past 36 months;
- Concomitant corticosteroid therapy, including high-dose inhaled corticosteroids;
- Receipt of immunostimulants;
- Receipt of parenteral immunoglobulin, blood products and/or plasma derivates within the past 3 months;
- Suspected or known HIV, HBV or HCV infection;
- Acute disease and/or axillary temperature ≥37oC within the past 3 days;
- Vaccine therapy within the past 4 weeks;
- Influenza vaccination (any kind) within the past 6 months;
- Experimental drug therapy within the past 4 weeks;
- Concomitant participation in another clinical study;
- +3 more criteria
