H1N1 Vacine and being sick (the two not related)

I got the H1N1 vaccine today. I had to go to work for a couple of hours today to do our annual competencies. On my way out I saw my manager who said, "Do you want to get the H1N1 vaccine?" I wasn't planning on getting it then, but had decided I was going to get the H1N1 vaccine for my son's sake since I work in the Emergency Room. So I got the shot. And today, I am a little sick. It is just a cold and has nothing to do with the vaccine. I caught the cold from my son. What a fun day! (said sarcastically)
