Primary

MeasureTime frame
Main Objective: Evaluate safety and tolerability of the study vaccines described below as compared to one and two 0.25 mL IM doses of trivalent inactivated influenza vaccine (TIV) and as compared to a marketed trivalent inactivated influenza vaccine: A. One and/or two 0.25 or 0.50 mL IM doses of quadrivalent influenza vaccine (TIV formulated with a second B strain; hereafter referred to as QIV). B. One and/or two 0.25 or 0.50 mL IM doses of TIV formulated with no dose, eighth dose, quarter dose, half dose, or full dose of adjuvant (MF59). C. One and/or two 0.25 or 0.50 mL IM doses of QIV formulated with either 0, quarter dose, half dose, or full dose of adjuvant (MF59). in unprimed healthy children aged 6 months to <36 months. Safety will be evaluated by collection of spontaneously reported adverse events (AEs) and tolerability will be evaluated by collection of solicited injection site reactions and solicited systemic reactions;Secondary Objective: Immunogenicity -identify non-inferior study vaccine formulations with a lower MF59 content than in pediatric doses of TIV with half dose MF59, as assessed by immunogenicity -identify study vaccine formulations that are superior to pediatric doses of TIV with half dose MF59 -identify vaccine combination that are superior to pediatric doses of a marketed comparator trivalent influenza vaccine -evaluate whether a one-dose schedule provide a similar immunogenicity as a two-dose schedule -evaluate whether the addition of a 2nd influenza B strain increases the antibody responses to this same influenza B strain -determine whether the addition of a 2nd influenza B strain to a TIV vaccine increases cross-reactive seroprotection against A/H3N2, A/H1N1 and the 1st influenza B strain, as assessed 3 to 4 weeks post final IM injection;Primary end point(s): Main objectives will be tested using homologous strain-specific antibodies assessed 4 weeks post 1st (Day 29)and 3 weeks post 2nd IM (Day 50) vaccination. In addition, antibody ti
