Not a lot of point taking the vaccination if you've already contracted swine flu - horses/doors/stables come to mind. I've had the flu, not pleasant but survivable if reasonably healthy. I can utterly understand that if you have underlying health complications, you would not want to get it, so go for the jab. [incidentally, friends in the health business tell me that the site of the injection hurts like billio for a couple of days.]
