Grade 3 drowsiness was defined as drowsiness that prevented normal activity. Any fever was defined as subjects with a documented temperature of greater than or equal to (≥) 38°C/100.4°F by any route and all subjects reporting temperature less than (< )38°C but with missing values (MC) for at least one day during the solicited period.

Any was defined as occurrence of any symptom regardless of intensity grade or relation to vaccination and related was an event assessed by the investigator as causally related to the study vaccination.
    Time Frame During the entire study period [approximately 28 days (primed subjects) and 56 days (unprimed subjects)]

    Outcome Measure Data

    Analysis Population Description
    The analysis was performed on the Pediatric-Total Vaccinated cohort which included all subjects aged 6 to 35 months, with at least one vaccine administration documented.
    Arm/Group Title Influsplit Tetra_IP 6-35m Group Influsplit Tetra_LP 6-35m Group
    Arm/Group Description Subjects in the Influsplit Tetra_IP group aged between 6 months to 35 months received 1 dose (primed subjects) at Day 0 and 2 doses (unprimed subjects) at Days 0 and 28 of Influsplit Tetra™ vaccine produced by investigational process (IP). Influsplit Tetra™ vaccine produced by IP was administered intramuscularly the anterolateral region of left thigh for subjects below 12 months of age and in the deltoid region of left or non-dominant arm in subjects ≥ 12 months of age (Day 0) and in the anterolateral region of right thigh for subjects below 12 months of age and in the deltoid region of right or dominant arm in subjects ≥ 12 months of age (Day 28). Subjects in the Influsplit Tetra_LP group aged between 6 months to 35 months received 1 dose (primed subjects) at Day 0 and 2 doses (unprimed subjects) at Days 0 and 28 of Influsplit Tetra™ vaccine produced by licensed process (LP). Influsplit Tetra™ vaccine produced by LP was administered intramuscularly the anterolateral region of left thigh for subjects below 12 months of age and in the deltoid region of left or non-dominant arm in subjects ≥ 12 months of age (Day 0) and in the anterolateral region of right thigh for subjects below 12 months of age and in the deltoid region of right or dominant arm in subjects ≥ 12 months of age (Day 28).
