Summary

The primary objective of this study was to perform a variety of assays on blood, serum, nasal wash and cell samples obtained from healthy adult subjects for the purposes of developing assays for application in the further investigation of immune responses generated by influenza virus vaccine, trivalent, types A \& B, live, cold-adapted (liquid formulation CAIV-T; Wyeth, Marietta, PA).

Conditions

Interventions

BIOLOGICAL

CAIV-T

Liquid CAIV-T vaccine for this study consisted of three cold-adapted, attenuated, reassortant strains representing the hemagglutinin (HA) and neuraminidase (NA) antigens of the A/New Caledonia/20/99 (H1N1), A/Panama/2007/99 (H3N2) and B/Yamanashi/166/98 influenza virus strains. The reassortant vaccine strains were grown in specific pathogen-free (SPF) eggs and the allantoic fluid, which contained virus, was harvested, concentrated and purified. Each dose of CAIV-T used in this study was formulated to contain approximately 107 FFU of each of the 6:2 influenza reassortant vaccine strains.

BIOLOGICAL

TIV

TIV in this study consisted of Flushield™, manufactured by Wyeth Vaccines, Marietta, PA, USA. Each 0.5 mL dose contained no less than 15 ug of the hemagglutinin antigens from each of the A/New Caledonia/20/99 (H1N1), A/Panama/2007/99 (H3N2), and B/Yamanashi/166/98 strains, making TIV in this study antigenically matched to the influenza strains contained in CAIV-T.

BIOLOGICAL

Placebo

Placebo in this study consisted of physiological saline. The total volume of 0.2 mL was administered intranasally with a spray applicator (approximately 0.1 mL into each nostril).
