Last time I had the flu and was sick enough to actually go to the doctor, the doc asked if I had gotten a flu shot and I said no, never. He wandered off with a knowing accusing look on his face. A few minutes later his assistant came in and I said something to the effect that I should have gotten the shot this year. She told me the vaccine they were pushing did not cover ANY of the flu strains going around, including mine. I asked why the doc was giving me dirty looks for not taking it, and she said he does that to everyone.
