- Primary Outcome Measures
Name Time Method Main Objective: To evaluate the immunogenicity of two 0.25 intramuscular (IM) injections of Agrippal™ S1, Influvac™, and Vaxigrip™ administered 4 weeks apart.;Secondary Objective: To evaluate safety and tolerability of two 0.25 mL intramuscular injections of Agrippal™ S1, Influvac™, and Vaxigrip™ administered 4 weeks apart.;Primary end point(s): There are no standard CHMP criteria for assessing immunogenicity in the age groups under evaluation. Therefore, the immunogenicity of the three vaccines will be determined based on the evaluation pre- and post-immunization GMTs and of other immunogenicity measures, such as sero-protection rate and sero-conversion rate after vaccination.
