E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the antibody response to each influenza vaccine antigen, as measured by Haemagglutination Inhibition (HI) test at 21 days post-immunization in non-elderly adult and elderly subjects in compliance with the requirements of the current EU recommendations for clinical trials related to yearly licensing of influenza vaccines (CPMP/BWP/214/96). |
|
E.2.2 | Secondary objectives of the trial |
To evaluate safety of a single IM (intramuscular) dose of the subunit influenza vaccine Fluvirin® in non-elderly adult and elderly subjects in compliance with the requirements of the current EU recommendations for clinical trials related to yearly licensing of influenza vaccine (CPMP/BWP/214/96). |

E.3 | Principal inclusion criteria |
Subjects eligible for enrollment into this study are male and female adult volunteers who are:
1. >18 years of age or older, mentally competent, willing and able to give written informed consent prior to study entry; 2. available for all the visits scheduled in the study and able to comply with all study requirements 3. in general good health as determined by: a) medical history b) physical examination c) clinical judgment of the investigator
Written informed consent must be obtained from all the subjects before enrollment in the study after the nature of the study has been explained. |

E.4 | Principal exclusion criteria |
Subjects are not to be enrolled into the study if at least one of the following criteria is fulfilled:

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, polymixin) 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 parenteral or oral corticosteroid 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. The subject has a bleeding diathesis or condition 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 child-bearing potential unwilling to practice acceptable contraception for the duration of the study (21 days). 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, the subject has 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. The subject has experienced an acute exacerbation of a COPD within the past 14 days 11. The subject has experienced fever (i.e. axillary temperature ≥38.0°C) within the last 3 days 12. Severely obese with Body Mass Index (BMI) > 35 kg/m2 13. Any condition, which, in the opinion of the investigator, might prevent the subject from participation or interfere with the evaluation of the study objectives
Site personnel involved in evaluation of safety and their immediate relatives are excluded from participation. |

E.5 End points |
E.5.1 | 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 titre should be > 40% · Mean geometric increase should be > 2.5 · The proportion of subjects achieving an HI titre ≥ 40 or SRH titre ≥ 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 titre should be > 30% · Mean geometric increase should be > 2.0 · The proportion of subjects achieving an HI titre ≥ 40 or SRH titer ≥ 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.
In HI tests, seroconversion or significant increase in antibody titre corresponds to: · negative prevaccination serum / postvaccination serum area ≥ 40 · at least a four-fold increase in titre from positive prevaccination serum
In SRH tests, seroconversion or significant increase in antibody titre corresponds to: · negative prevaccination serum / postvaccination serum ≥ 25 mm2 · at least a 50% increase in area from positive prevaccination serum
The statistical parameters to be determined are: · Geometric mean of prevaccination serum anti-HA titres · Increase in the geometric mean of antibody titre · Proportion of subjects with seroconversion or significant increase · Proportion of subjects above a particular antibody titer (for SRH area ≥ 25 mm2, for HI: titer ≥ 40) before vaccination · Proportion of subjects above a particular antibody titer (for SRH area ≥ 25 mm2, for HI: titer ≥ 40) after vaccination |
