Safety and Immunogenicity Study of an Inactivated Influenza Vaccine (Whole Virion, Vero Cell Derived)

The objective of this study is to assess the safety and immunogenicity of inactivated influenza vaccine (whole virion, Vero cell derived). Subjects will be randomly assigned to receive a single injection of whole virion, Vero cell derived or egg derived influenza vaccine on Day 0. Subjects will return to the study site for safety evaluation at predetermined intervals for 180 days after vaccination. Subjects will also have blood drawn at predetermined intervals to measure their immunologic response to vaccination.
