Hi Kristy,

I've had a flu shot for the past few years, and have had no reactions.
As long as the vacination is not a live vacine its ok.
I think having the flu shot has certainly helped, some members of my family have had terrible flus this year, and I have missed them so far, but the flu shot only generally covers a very limited number/strands of the "flu".

Hope this helps a little
