A member asked:

If you inhale a flu virus, like from someones sneeze or wet cough, will you definitely get the flu too, or can your body sometimes fight it off?

A doctor has provided 1 answer

Sometimes no illness: Some people have no symptoms after catching the flu virus. Nobody knows how to predict which persons will have no symptoms after catching the virus. Also, because we don't know who is NOT immune to a particular flu virus, we really don't know how many non-immune people have no symptoms after catching the virus. I would guess that most non-immune people do get symptoms after catching the virus.
