There is a very small chance that you might be allergic to the flu vaccine, but medically speaking, the virus cannot reproduce in your cells, making you sick like the an active influenza strain will.
I did get sick from the shot. I didn't say I got the flu, but I suffered a fever and aches and pains for days after the shot. The CDC says these are potential side effects. So, no, it wasn't purely coincidence that I went from feeling completely healthy to sick the day after getting the flu shot.
