Brief summary

To describe the safety of the 2004-2005 pediatric formulation of the inactivated, split-virion influenza vaccine Fluzone®, given in the two-dose schedule in accordance with the Package Insert, in children aged ≥ 6 months to \< 36 months. To describe the immunogenicity of the 2004-2005 inactivated, split-virion influenza vaccine Fluzone®, administered in a two-dose schedule in accordance with the Package Insert, in children aged ≥ 6 months to \< 36 months

Detailed description

To provide the Centers for Biologic Evaluation and Research (CBER) with sera collected from healthy children receiving the 2004-2005 formulation of the inactivated, split-virion influenza vaccine Fluzone® for further study by the Food and Drug Administration (FDA), Centers for Disease Control and Prevention (CDC), and the World Health Organization (WHO).
