Primary	Efficacy Endpoint: First occurrence of culture confirmed influenza, due to influenza Type A and/or B virus antigenically matched by ferret antigenicity testing to the strains selected for the seasonal influenza vaccine	First occurrence of culture confirmed influenza, due to influenza Type A and/or B virus antigenically matched by ferret antigenicity testing to the strains selected for the seasonal influenza vaccine, occurring at >14 days after the last vaccination and until the end of the influenza season, in association with protocol-defined ILI symptoms	Day 14 to Day 180
Secondary	Efficacy Endpoint: First occurrence of culture confirmed influenza caused by influenza virus strains antigenically dissimilar to the influenza strains selected for the seasonal influenza vaccine	First occurrence of culture confirmed influenza caused by influenza virus strains antigenically dissimilar to the influenza strains selected for the seasonal vaccine occurring at >14 days after the last vaccination and until the end of the influenza season, in association with protocol-defined ILI symptoms	Day 14 to Day 180
Secondary	Efficacy Endpoint: First occurrence of culture confirmed influenza due to any influenza Type A and/or Type B virus regardless of antigenic match to the influenza strains selected for the seasonal influenza vaccine	First occurrence of culture confirmed influenza due to any influenza Type A and/or Type B virus regardless of antigenic match to the influenza strains selected for the seasonal influenza vaccine, occurring at >14 days after the last vaccination and until the end of the influenza season, in association with protocol-defined ILI symptoms	Day 14 to Day 180
Secondary	Efficacy Endpoint: First occurrence of RT-PCR confirmed moderate-to-severe influenza due to any influenza Type A and/or Type B virus regardless of antigenic match to the influenza strains selected for the seasonal influenza vaccine	First occurrence of RT-PCR confirmed moderate-to-severe influenza due to any influenza Type A and/or Type B virus regardless of antigenic match to the influenza strains selected for the seasonal influenza vaccine, occurring at >14 days after the last vaccination and until the end of the influenza season	Day 14 to Day 180
Secondary	Immunogenicity Endpoint: a) Prevaccination and postvaccination Geometric Mean Titer (GMT)	The measures for immunogenicity are determined by a haemagglutination inhibition [HI] and/or a microneutralization [MN] assay prior to first vaccination and 28 days after last vaccination for all four influenza strains	Day 1 and 28 days after last vaccination
Secondary	Immunogenicity Endpoint: Seroconversion rates (SCR)	The measures for immunogenicity are determined by a HI and/or a MN assay prior to first vaccination and 28 days after last vaccination for all four influenza strains; SCR is defined as the percentage of subjects with either a prevaccination HI (or MN) titer < 1:10 and a postvaccination HI (or MN) titer = 1:40, or a prevaccination HI (or MN) titer = 1:10 and a = 4-fold increase in postvaccination HI (or MN) titer	Day 1 and 28 days after last vaccination
Secondary	Immunogenicity endpoint: Geometric Mean Ratio (GMR)	The measures for immunogenicity are determined by a haemagglutination inhibition [HI] and/or a micro neutralization [MN] assay prior to first vaccination and 28 days after last vaccination for all four influenza strains; GMR is the geometric mean of the fold increase of post-vaccination HI (or MN) titer over the pre-vaccination HI (or MN) titer	Day 1 and 28 days after last vaccination
