shot to the heart

Here's my issue with the flu shot, I'm convinced that by getting it that I will jinx myself into catching it. I caught a bug last year that was so terrible it almost ruined my trip to Colorado to ski with three of my best guy friends. Was it the flu? I'll never know but I do know it was awful. So what do you think? Can anyone recommend where they go their own flu shot? Dress credit to The Blondes.
