Brief Summary:

The aim of this study is to evaluate the safety and immunogenicity of Fluzone® Quadrivalent vaccine in participants aged 6 months to < 9 years at enrollment, divided into 2 age strata (6 months to < 36 months and 3 years to < 9 years)

Primary Objective:

  • To describe the safety of the 2013-2014 formulation of Fluzone Quadrivalent vaccine, administered in a 1- or 2-dose schedule, in accordance with Advisory Committee on Immunization Practices (ACIP) recommendations, in children 6 months to < 9 years of age.

Observational Objectives:

  • To describe the immunogenicity of the 2013-2014 formulation of Fluzone Quadrivalent vaccine, administered in a 1- or 2-dose schedule in accordance with ACIP recommendations, in children 6 months to < 9 years of age.
  • To submit sera from subjects to the Center for Biologics Evaluation and Research (CBER) for further analysis by the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA) to support formulation recommendations for subsequent influenza vaccines.

Condition or disease Intervention/treatment Phase
Influenza Biological: Fluzone® Quadrivalent Influenza Virus Vaccine, No Preservative Phase 4

Detailed Description:

Participants will be assigned to the appropriate age group (6 months to < 36 months of age or 3 years to < 9 years of age) based on the subject's age at the time of enrollment.

Solicited adverse event (AE) information will be collected for 7 days after each vaccination, unsolicited AE information will be collected from Visit 1 to Visit 2, or to Visit 3 for those subjects receiving 2 doses. Serious adverse event information will be collected from Visit 1 to Visit 2, or Visit 3 for those subjects receiving 2 doses.

Immunogenicity will be evaluated in all subjects prior to vaccination on Day 0 (Visit 1) and at Day 28 after the final vaccination using the hemagglutination inhibition technique. For each influenza vaccine strain, pre- and post-vaccination geometric mean titers will be calculated.

Primary Outcome Measures :
  1. Number of Participants Reporting Solicited Injection-Site or Systemic Reactions Following Vaccination With the 2013-2014 Formulation of Fluzone® Quadrivalent, Influenza Vaccine [ Time Frame: Day 0 up to Day 7 post-vaccination ]

    Solicited injection-site reactions (6 months to <36 months of age): Tenderness, Erythema, and Swelling. Systemic reactions: Fever (Temperature), Vomiting, Crying Abnormal, Drowsiness, Appetite loss, and Irritability. Grade 3: Tenderness, Cries if limb is moved; Erythema and Swelling, ≥50 mm; Fever, >103.1ºF; Vomiting, ≥6 episodes per 24 hours or requiring parenteral hydration; Crying abnormal, >3 hours; Drowsiness, Sleeping most of the time; Appetite lost, Refuses ≥3 feeds/meals or refuses most feeds/meals; Irritability, Inconsolable.

    Solicited injection-site reactions (3 years to < 9 years of age): Pain, Erythema, and Swelling. Systemic Reactions: Fever (Temperature), Headache, Malaise, and Myalgia. Grade 3: Pain, Incapacitating, unable to perform usual activities; Erythema and Swelling, ≥50 mm; Fever, ≥102.1ºF; Headache, Malaise, and Myalgia, Significant, prevents daily activity.



Secondary Outcome Measures :
  1. Geometric Mean Titers (GMTs) of Influenza Antibodies Before and Following Vaccination With the 2013-2014 Formulation of Fluzone® Quadrivalent, Influenza Vaccine [ Time Frame: Day 0 (pre-vaccination) and Day 28 after final vaccination ]
    Influenza virus antibodies were measured using a hemagglutination inhibition (HAI) assay.

  2. Number of Participants With Seroprotection Before and Following Vaccination With the 2013-2014 Formulation of Fluzone® Quadrivalent, Influenza Vaccine [ Time Frame: Day 0 (pre-vaccination) and Day 28 after final vaccination ]
    Influenza virus antibodies were measured using an HAI assay. Seroprotection was defined as a titer ≥40 (1/dilution).

  3. Number of Participants Achieving Seroconversion Following Vaccination With the 2013-2014 Formulation of Fluzone® Quadrivalent, Influenza Vaccine [ Time Frame: Day 0 (pre-vaccination) and Day 28 after final vaccination ]
    Influenza virus antibodies were measured using an HAI assay. Seroconversion was defined as either a pre-vaccination HAI titer < 1:10 and a post-vaccination titer ≥ 1:40 or a pre-vaccination titer ≥ 1:10 and a ≥ 4-fold increase in post-vaccination titer.

  4. Geometric Mean Titer Ratios (GMTRs) of Influenza Antibodies Following Vaccination With the 2013-2014 Formulation of Fluzone® Quadrivalent, Influenza Vaccine [ Time Frame: Day 0 (pre-vaccination) and Day 28 after final vaccination ]
    Influenza virus antibodies were measured using an HAI assay. Geometric mean titer ratios are the geometric means of the individual post-vaccination/pre-vaccination titer ratios for each hemagglutinin antigen contained in the vaccine.
