Aktiver Komparator: CAIV-T
CAIV-T contains 3 cold-adapted influenza virus strains (A/H1N1, A/H3N2, B) concentrated and refined by centrifugal separation from the chorioallantoic membrane of specific pathogen-free (SPF) eggs, containing SPG (sucrose-phosphate-glutamate), arginine, and acid hydrolyzed pig gelatin as stabilizers.
Subjects were inoculated once with about 0.1 mL of investigational vaccine in each nasal cavity (a total of 0.2 mL) using a nebulizer.
