Trial to Compare the Safety, Tolerability, and Efficacy of Influenza Virus Vaccine, (CAIV-T) With Inactivated, Influenza Vaccine, Trivalent, Types A & B, in Adults Aged 60 Years and Older Against Culture-confirmed Influenza

Summary

To demonstrate that the efficacy over a defined surveillance period against culture-confirmed influenza-illness caused by community-acquired subtypes antigenically similar to those contained in the vaccine, in adults aged at least 60 years at enrollment, of a single intranasally (IN) -administered dose of a liquid formulation of influenza virus vaccine,(CAIV-T) is non inferior compared with that of a single dose of commercially available influenza vaccine inactivated (TIV) administered intramuscularly (IM) prior to the anticipated commencement of the influenza season.
