Brad,
I think that what he was talking about when he talked about the vaccine "not being long lasting" was that the components of the vaccine are changed each year based upon the formula of the three dominate strains of flu being forecast by WHO for the coming flu season. This isn't an issue since all vaccine manufactures are in the same boat.

What is unique about this vaccine is, as you point out, the nasal spray delivery system and the fact that the cold adapted virus unique to AVIR produces the immune responce but without the flu side effects.
