I was wondering can you still be contagious during a secondary immune response to influenza?

I know that people can be asymptomatic carriers of bacteria, ie. can pass the organism on, but not be sick with it.

Viruses, on the other hand, need to replicate inside of a living host cell. Perhaps, people could carry them in their nose for a very short period of time before they have a chance to infect and cause disease, but this seems less likely to me.
