Brief Summary:

Primary Objective:

To provide the Center for Biologics Evaluation and Research (CBER) with sera collected from healthy children receiving the 2008-2009 formulation of the inactivated, split-virion influenza vaccine Fluzone® for further study.

Observational Objectives:

To describe the safety of the 2008-2009 pediatric formulation of Fluzone® vaccine, administered in a one- or two-dose schedule in accordance with Advisory Committee on Immunization Practices (ACIP) recommendations, in children ≥ 6 months to < 5 years of age.

To describe the immunogenicity of the 2008-2009 pediatric formulation of Fluzone® vaccine, administered in a one- or two-dose schedule in accordance with ACIP recommendations, in children ≥ 6 months to < 5 years of age.


Condition or disease Intervention/treatment Phase
Influenza Orthomyxoviridae Infections Biological: Influenza Virus Vaccine No Preservative: Pediatric Dose Phase 4

Detailed Description:
The Advisory Committee on Immunization Practices (ACIP) has in recent years recommended that all healthy children aged 6 through 59 months receive influenza vaccine. Because of the growing emphasis on influenza immunization of infants and young children, Center for Biologics Evaluation and Research (CBER) has expressed interest in receiving sera from children who have been vaccinated with the current formulation of Fluzone® vaccine. These sera will be tested to evaluate each individual's immune response to the current formulation of Fluzone® vaccine and will also be used to evaluate circulating influenza strains in order to support formulation recommendations for the subsequent year (particularly for influenza B strains, which predominantly affect the young).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants With Solicited Local and Systemic Reactions After Fluzone® Vaccination 1 [ Time Frame: Day 0 to Day 3 post-vaccination 1 ]
    Solicited local reactions: Tenderness, pain, erythema, and swelling. Systemic reactions: Fever (temperature), vomiting, crying abnormal, drowsiness, appetite lost, irritability, headache, malaise, and myalgia.

  2. Number of Participants With Solicited Local and Systemic Reactions After Fluzone® Vaccination 2 [ Time Frame: Day 0 to Day 3 post-vaccination 2 ]
    Solicited local reactions: Tenderness, pain, erythema, and swelling. Systemic reactions: Fever (temperature), vomiting, crying abnormal, drowsiness, appetite lost, irritability, headache, malaise, and myalgia.


Other Outcome Measures:
  1. Geometric Mean Titers (GMTs) of Antibodies to Vaccine Influenza Strains Determined by Hemagglutination Inhibition (HAI) Assay After Fluzone® Vaccination [ Time Frame: Day 28 post-single dose or Day 21 post-Dose 2 ]
  2. Percentage of Participants With Influenza Titers ≥ 1:40 After Fluzone® Vaccination (Seroprotection) [ Time Frame: Day 28 post-single dose or Day 21 post-Dose 2 ]
    Seroprotection was defined as a post-vaccination Hemagglutination inhibition titer ≥ 1:40. Data presented for all participants and those enrolled at age 6 to 35 months.

  3. Percentage of Participants With Influenza Titers ≥ 1:40 After Fluzone® Vaccination (Seroprotection) [ Time Frame: Day 28 post-single dose or Day 21 post-Dose 2 ]
    Seroprotection was defined as a post-vaccination Hemagglutination inhibition titer ≥ 1:40. Data presented for participants enrolled at age 36 to 59 months.

  4. Percentage of Participants With at Least a 4-Fold Rise in Influenza Titers After Fluzone® Vaccination (Seroconversion) [ Time Frame: Day 28 post-single dose or Day 21 post-Dose 2 ]
    Seroconversion was defined as a ≥ 4-fold increase in post-vaccination Hemagglutination inhibition titer. Data presented for all participants and those enrolled at age 6 to 35 months of age.

  5. Percentage of Participants With at Least a 4-Fold Rise in Influenza Titers After Fluzone® Vaccination (Seroconversion) [ Time Frame: Day 28 post-single dose or Day 21 post-Dose 2 ]
    Seroconversion was defined as a ≥ 4-fold increase in post-vaccination Hemagglutination inhibition titer. Data presented for participants enrolled at age 36 to 59 months.
