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.

Conditions

Interventions

BIOLOGICAL

Cold-adapted influenza vaccine trivalent (CAIV-T)

Liquid CAIV-T vaccine for this study consisted of 3 cold-adapted, attenuated, reassortant strains, representing the HA and NA antigens of the A/New Caledonia/20/99 (H1N1), A/Panama/2007/99 (H3N2), and B/Victoria/504/2000 influenza strains. The vaccine contained no preservatives and had a pH of 7.2 ± 0.5.

BIOLOGICAL

Trivalent Inactivated Vaccine (TIV)

Commercially available TIV, inactivated influenza vaccine (Split Virion) BP (Aventis Pasteur MSD, Lyon, France) was administered IM according to the manufacturer's dosing instructions (one 0.5-mL IM dose for adults).
