I haven't gotten a flu shot in years, but I may start next year. I've had two major bouts so far this year. Not unexpected, since my wife is an elementary teacher and my job involves going to peoples' offices to fix computers. It's like we're both in the hot zones all winter long.
What I'm really interested in though is the pneumonia vaccine - it seems like every time I get sick it goes into my lungs and threatens to turn into pneumonia.
