Phase: Phase 1/Phase 2

Status: Completed

Sponsored by: Sanofi Pasteur, a Sanofi Company

Summary

Primary Objective: To describe the safety of the 2004-2005 pediatric formulation of the inactivated, split-virion influenza vaccine Fluzone®, given in the two-dose schedule (described in the package insert for vaccine-naļve young children) to the investigational and control groups. Observational Objective: To describe the percentage of protective Hemagglutination Inhibition (HAI) antibody titers (following a 2-dose Fluzone® immunization series) to each of the 3 vaccine antigens among the investigational and control groups.

Clinical Details

Official title: Proof of Concept Study of the Safety and Immunogenicity of Influenza Virus Vaccine Fluzone® 2004-2005 Among Healthy Children 2 Months vs 6 Months of Age

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention

Primary outcome: Percentage of Participants With Solicited Local and Systemic Reactions After Vaccination With FluzoneĀ® 2004-2005 Pediatric Formulation.

Detailed description: This is an observational and descriptive study that will provide preliminary comparative information about the safety and immunogenicity of FluzoneĀ® vaccine among children aged 6 to 12 weeks (the investigational group, also referred to as the 2-month-old group) versus children aged 24 to 36 weeks (the control group, also referred to as the 6-month-old group). The study is not designed to achieve any preset statistical power, and no hypotheses will be tested.
