Current Primary Outcome Measures

• Seroconversion Rates after Vaccination with Multi-dose Quadrivalent Influenza Vaccine or Single-dose Quadrivalent Influenza Vaccine [Time Frame: Day 28 (post-last vaccination)]

  Anti-HA antibody titers against the 4 influenza strains are assessed by an HAI assay. Seroconversion is defined as either post-vaccination titer ≥ 40 (1/dil), or pre-vaccination titer ≥ 10 (1/dil) and ≥ 4-fold increase in post-vaccination titer

• GMT Ratio after Vaccination with Multi-dose Quadrivalent Influenza Vaccine or Single-dose Quadrivalent Influenza Vaccine [Time Frame: Day 28 (post-last vaccination)]

  Anti-HA antibody titers against the 4 influenza strains are assessed by an HAI assay. GMT ratio is assessed as the individual ratio of post-/pre-vaccination titers

• Geometric Mean Titers (GMTs) of Antibodies after Vaccination with Multi-dose Quadrivalent Influenza Vaccine or Single-dose Quadrivalent Influenza Vaccine [Time Frame: Day 28 (post-last vaccination)]

  Anti-hemagglutinin (HA) antibody titers against the 4 influenza strains are assessed by a hemagglutination inhibition (HAI) assay

Original Primary Outcome Measures

Current Secondary Outcome Measures

• Percentage of Participants Reporting Solicited Injection Site or Systemic Reactions after Vaccination with Multi-dose Quadrivalent Influenza Vaccine or Single-dose Quadrivalent Influenza Vaccine [Time Frame: Day 0 (pre-vaccination) to Day 7 (after any vaccination)]

  Solicited injection site reactions are tenderness/pain,erythema, swelling, induration, ecchymosis, and solicited systemic reactions are fever, vomiting, crying abnormal, drowsiness, appetite lost, irritability (for children ≤ 23 months), and fever, headache, malaise, myalgia, and shivering (for children 2 to 17 years)

Study Design

Brief Title	Immunogenicity and Safety of a Multi-Dose Quadrivalent Influenza Vaccine
Official Title	Immunogenicity and Safety of a Multi-Dose Quadrivalent Influenza Vaccine in Children Aged 6 Months to 17 Years
Brief Summary	The aim of the study is to to assess the immunogenicity and safety of a quadrivalent influenza vaccine in a multi-dose presentation compared to a quadrivalent influenza vaccine in single-dose presentation, in children aged 6 months to 17 years.
Detailed Description	Participants aged 9 to 17 years will receive one dose of either the multi-dose quadrivalent influenza vaccine or the quadrivalent influenza vaccine in a single-dose presentation and participants aged 6 months to 8 years will receive 2 doses of either vaccine, 28 days apart. All participants will provide a pre-vaccination blood sample on Day 0 and a post-vaccination blood sample either on Day 28 (participants aged 9 to 17 years) or on Day 56 (participants aged 6 months to 8 years) for immunogenicity testing. All participants will be followed for safety evaluation up to 6 months after the last vaccination.
