To evaluate the immunogenicity of one and two intramuscular (IM) injections of the MF59-adjuvanted H1N1sw monovalent influenza vaccine in adult and elderly subjects previously exposed to 2009/10 NH formulation of TIV and in those not yet vaccinated against seasonal influenza 2009/10, with respect to CHMP criteria. To evaluate immunogenicity of one and two IM injections of full and half dose of a H1N1sw monovalent influenza vaccine concomitantly administered with a single IM dose of a seasonal TIV in adult subjects not yet vaccinated against seasonal influenza 2009/10, with respect to CHMP criteria. To evaluate immunogenicity of a single IM injection of a seasonal TIV when concomitantly administered with one and two IM injections of full and half dose of a H1N1sw monovalent influenza vaccine in adult subjects not yet vaccinated against seasonal influenza 2009/10, with respect to CHMP criteria. |

Individuals who are not able to comprehend and to follow all required study procedures for the whole period of the study or who do not consent to the retention of the subject�s serum samples after study completion; 2. Individuals with behavioral or cognitive impairment or psychiatric disease that, in the opinion of the investigator, may interfere with the subject`s ability to participate in the study; 3.

E.5 End points |
E.5.1 | Primary end point(s) |
Immunogenicity Endpoints The measures for immunogenicity as determined by HI are as follows: 1. Geometric mean HI titer (GMT) on Day 1, Day 22, Day 29 and Day 43 2. Day 22/Day1, Day 29/Day1, Day 43/Day 1, Day 29/Day 22, and Day 43/Day 22, geometric mean ratio (GMR) of HI; 3. Percentage of subjects achieving a seroconversion or a significant increase (defined as: HI &#8805;1:40 for subjects negative at baseline [<1:10]; a minimum 4-fold increase in HI titer for subjects positive at baseline [HI&#8805;1:10]) on Day 22, Day 29 and Day 43; 4. Percentage of subjects with a HI titer &#8805;1:40 (i.e. seroprotection) on Day 1, Day 22, Day 29 and Day 43. Criteria for success as determined by HI: For the monovalent H1N1sw vaccine, the immunogenicity criteria for success, as determined by HI, related to the EMEA/CPMP/VEG/4717/2003-Rev.1 (pandemic guideline) and EMEA/CHMP/VWP/263499/2006 (pre-pandemic guideline) are: For adults subjects aged 18-60 years: The percentage of subjects with seroconversion or significant increase in HI antibody is > 40% The percentage of subjects achieving an HI titer &#8805;40 is > 70%. The GMR is >2.5 For elderly subjects aged &#8805;61 years: The percentage of subjects with seroconversion or at significant increase in HI antibody is > 30% The percentage of subjects achieving an HI titer &#8805;40 is > 60%. The GMR is >2.0 All three criteria should be met in each age group to fulfill regulatory requirements. For the trivalent seasonal vaccine, the immunogenicity criteria for success, as determined by HI, related to the CHMP/BWP/214/96 guideline, are the same as listed above. However it is sufficient that at least one criterion per each strain should be achieved to fulfil regulatory requirements. Safety Endpoints The safety of the study vaccine will be assessed based on number of subjects exposed and with reported local and systemic reactions, as well as the number of subjects with reported unsolicited adverse events per vaccine and age group. Solicited local reactions will include ecchymosis, erythema, induration, swelling and pain at injection site; solicited systemic reactions will include headache, arthralgia, chills, fatigue, malaise, myalgia, nausea, sweating, and fever. Where applicable, reactogenicity after each injection will be summarized according to the Brighton collaboration case definition [Bonhoeffer J et al. Vaccine 2009;27(16): 2282-8] (1). Unsolicited reactions will include all AEs, including all SAEs, onset of chronic diseases and AEs that lead to withdrawal from the study and will be collected for the entire study period (from Day 1 to Day 43). |
