Flu Shot

I got a flu shot today. I was hesitant to get it, because the last time I got a shot (over 10 years ago) I got the flu. Before that I never got the flu, so I was convinced that I got it due to the shot. Now after a lot of research, I see that I was wrong and that is virtually impossible to get the flu from the shot. So hopefully I will flu free this year and the pain I am feeling in my arm right now will be worth it.
