Study Description

Brief Summary:

The study will evaluate the safety and immunogenicity of the 2014-2015 formulation of Fluzone Quadrivalent vaccine, administered in a 1- or 2-dose schedule, in accordance with the Advisory Committee on Immunization Practices (ACIP) recommendations, in children 6 months to < 9 years of age.

Objective:

• To describe the safety of the 2014-2015 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.

Observational objectives:

• To describe the immunogenicity of the 2014-2015 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 available sera from each subject to Center for Biologics Evaluation and Research (CBER) for further analysis by the 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 Vaccine, No Preservative	Phase 4

Detailed Description:

Participants will be assigned to the appropriate age group based on the age at the time of enrollment. Participants will receive a dose of Fluzone Quadrivalent vaccine, those for whom 2 doses of influenza vaccine are recommended per ACIP guidance, will receive a second dose during Visit 2 (28 days after Visit 1).

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 (SAE) information will be collected the study. Immunogenicity will be evaluated in all participants prior to vaccination and at Day 28 after the final vaccination.

Outcome Measures

Primary Outcome Measures :

1. Percentage of Participants Reporting Solicited Injection-site or Systemic Reactions Following Vaccination With the 2014-2015 Formulation of Fluzone® Quadrivalent Influenza Vaccine [ Time Frame: Day 0 up to Day 7 post-any injection ]

   Solicited Injection-site: 6 to < 36 months - Tenderness, Erythema, and Swelling; 3 to < 9 years - Pain, Erythema, and Swelling. Solicited systemic reactions: 6 to < 36 months - Fever (Temperature), Vomiting, Crying abnormal, Drowsiness, Appetite lost, and Irritability; 3 to < 9 years - Fever, Headache, Malaise, and Myalgia.

   Grade 3: Fever, > 39.5˚C (6 to < 36 months), ≥ 39.0˚C (3 to < 9 years); Vomiting, ≥ 6 episodes/24 hours or requires parenteral hydration; Crying abnormal, > 3 hours; Drowsiness, Sleeping often/difficult to wake; Appetite lost, Refuses ≥ 3 or most meals; Irritability, Inconsolable; Headache, Malaise, and Myalgia, Significant, prevents daily activity.

Secondary Outcome Measures :

1. Geometric Mean Titers (GMTs) of Influenza Antibodies Before and Post Vaccination With the 2014-2015 Formulation of Fluzone® Quadrivalent Influenza Vaccine [ Time Frame: Day 0 (pre-vaccination) and Day 28 post-final vaccination ]
   Geometric titers of influenza antibodies were assessed using the hemagglutination inhibition (HAI) assay.
2. Number of Participants With Seroprotection Before and Following Vaccination With the 2014-2015 Formulation of Fluzone® Quadrivalent Vaccine [ Time Frame: Day 0 (pre-vaccination) and Day 28 post-final vaccination ]
   Influenza antibodies were assessed using the hemagglutination inhibition (HAI) assay. Seroprotection was defined as a titer ≥ 40 (l/dil) at pre-vaccination and at 28 days after the final vaccination.
3. Percentage of Participants With Seroconversion Following Vaccination With the 2014-2015 Formulation of Fluzone® Quadrivalent Vaccine [ Time Frame: Day 28 post-final vaccination ]
   Influenza antibodies were assessed using the hemagglutination inhibition (HAI) assay. Seroconversion is 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 2014-2015 Formulation of Fluzone® Quadrivalent Vaccine [ Time Frame: Day 28 post-final vaccination ]
   Geometric titer ratios of influenza antibodies were assessed using the hemagglutination inhibition (HAI) assay.
