In brief: 1-3 Days

He may be feeling the symptoms of the body simply "recognizing" the influenza vaccine.
However it is also equally likely he is coming down with a cold virus that just happens to be after he got the flumyst. If you have concerns about his health, see your pediatrician in the next day.
