study of fluzone vaccine administered by intradermal route in comparison with standard fluzone® in adults

Conditions: Orthomyxoviridae Infection; Influenza; Myxovirus Infection

Summary: this study is designed to test lot consistency of three different manufacturing lots and to generate safety and immunogenicity data of the investigational vaccine administered via the id route. primary objective: * to demonstrate lot consistency of the fluzone id manufacturing process. * to provide information concerning the immune response of fluzone id. secondary objectives: safety * to describe the safety profile of subjects who receive of fluzone id.

three lots of the investigational fluzone vaccine with the 2008/2009 northern hemisphere formulation will be administered intradermally (id) using the becton dickinson micro injection system.
