Facial ticks and Flu Shot?

My 7 year old daughter has facial ticks/excessive blinking and occasional humming. I am starting to wonder if the flu shot has something to do with it. This is the 3rd year in a row where 1 week after she gets the flu shot, she develops facial ticks/excessive blinking and occasional humming. It does go away after about 1-2 months. Is this coincidence (time of year) or flu shot? Has anybody else encountered such behavior after the flu shot?

I forgot to mention... she does not have Tourette's. I did not know which category to post this question in.

Exactly the same thing, one week after flu mist. Lasted about 3-4 weeks.

The flu shot may cause an Increase in tics due to stress/anxiety; nothing more.

My son does have Tourette's although we are currently investigating possible PANDAS. This is our 3rd year in a row that vocal tics started right after the flu shot. We were told last year it was just a coincidence but after this year he will not be getting any more flu shots.
