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.
Detailed description
Primary immunogenicity objectives * To assess immunogenicity 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, as measured by haemagglutination inhibition (HI) test 21 days after vaccination in compliance with the requirements of the current European Union recommendations as determined in CPMP/BWP/214/96. * To determine dose-effect relationship between one 0.5 mL 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 and immune response provoked 21 days after vaccination in terms of pre- and postimmunization HA titers as measured by HI test. Secondary immunogenicity objectives * To assess immunogenicity of one 0.5 mL 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, as measured by HI test 14 days after vaccination in compliance with the requirements of the current European Union recommendations as determined in CPMP/BWP/214/96. * To find the highest dose of FLUVAL AB-like trivalent influenza vaccine among 3.5μgHA, 6μgHA and 9μgHA the response of which differs from that of dose 15μgHA in terms of post-immunization HA titers as measured by HI test 21 days after vaccination. * To find the highest dose of FLUVAL AB-like trivalent influenza vaccine among 3.5μgHA, 6μgHA and 9μgHA the response of which differs from that of dose 15μgHA in terms of post-immunization HA titers as measured by HI test 14 days after vaccination. * To find the highest dose of FLUVAL AB-like trivalent influenza vaccine among 3.5μgHA, 6μgHA and 9μgHA the response of which differs from that of dose 15μgHA in terms of the percentage of subjects achieving seroconversion or significant increase in antibody titer at day 21 after vaccination. * To find the highest dose of FLUVAL AB-like trivalent influenza vaccine among 3.5μgHA, 6μgHA and 9μgHA the response of which differs from that of dose 15μgHA in terms of the percentage of subjects achieving seroconversion or significant increase in antibody titer at day 14 after vaccination. * To find the highest dose of FLUVAL AB-like trivalent influenza vaccine among 3.5μgHA, 6μgHA and 9μgHA the response of which differs from that of dose 15μgHA in terms of Day 21/Day 0 geometric mean titer ratios (GMTRs) as determined by HI. * To find the highest dose of FLUVAL AB-like trivalent influenza vaccine among 3.5μgHA, 6μgHA and 9μgHA the response of which differs from that of dose 15μgHA in terms of Day 14/Day 0 geometric mean titer ratios (GMTRs) as determined by HI. Safety and tolerability objective * To evaluate the safety of the administration of one 0.5 mL 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.

Eligibility
Inclusion criteria
* 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. * Absence of existence of any
