Exclusion criteria
Exclusion criteria: 1. Any serious chronic or acute disease such as: a. Cancer (leukemia, lymphomas, neoplasm), except for benign or localized skin cancer and non-metastatic prostate cancer not presently treated with chemotherapy b. Congestive heart failure c. Advanced arteriosclerotic disease d. Chronic obstructive pulmonary disease (COPD) requiring oxygen therapy and/or acute exacerbation of a COPD within the last 14 days. e.

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 (chronic therapy with immunosuppressive drugs, any parenteral or oral corticosteroid (substitution dose in case of absence of suprarenal function allowed) or cancer chemotherapy/radiotherapy) within the last 2 months 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.

| Main Objective: Immunogenicity Objectives To evaluate the antibody response to each influenza vaccine antigen, as measured by haemagglutination inhibition (HI) test on Day 0 and on Day 21, i.e., 21 days after immunization in non-elderly 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). Safety Objectives Safety Objectives To evaluate safety of a single IM (intramuscular) dose of the cell-derived influenza subunit vaccine (Optaflu) in non-elderly 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). ;Secondary Objective: ;Primary end point(s): MEASURES OF IMMUNOGENICITY: Influenza antibody levels in serum measured by HI test on Days 0 and 21. Any HI result <10 (undetectable) shall be expressed as 5 for purposes of calculation. Separately in each age group the following measures will be investigated: First, for each visit the number and proportion of subjects with a titre of antibodies of at least 40 (as measured by HI test) and the geometric means of titres (GMTs) will be determined. Second, the number and percentage of subjects with seroconversion or significant increase of titer as well as the mean geometric increase (GMT ratio) will be calculated from these data. MEASURES OF SAFETY: Incidences of local reactions (Days 0 to 3) including ecchymosis, erythema, induration, swelling and pain at the injection site) summarized by maximal severity and by age group. Incidences of systemic reactions (Days 0 to 3) including chills/shivering, malaise, myalgia, arthralgia, headache, sweating, fatigue and fever summarized by maximal severity and by age group. Incidences of adverse events (including local and systemic reactions with a duration beyond Day 3 post immunization) between Day 0 and the study termination visit Day 21 (± | — |
