My allergist told me that the flu shot was incubated in eggs.  Even though I
am an asthmatic, it is contra-indicated since I am allergic to eggs.
Therefore, although I don't know for sure it's GF status, I would presume
the other poster who said it was grown on wheat stems was incorrect, and if
you have no problem with eggs, you should consider taking it.
