VG22K effectively primes for RSV-specific memory T lymphocyte response. Splenocytes from mice previously primed with VG or VG22K were stimulated in vitro with RSV-infected naive spleen cells. Supernatants were collected 48 h later and analyzed for IL-2, IL-4, IL-5, and IFN-γ. IL-4 and IL-5 were not detected in culture supernatants from either group of animals (data not shown).
