I work in a hospital in MA and we haven't gotten it yet, and we work w/ flu patients. It is in pretty short supply, but I believe it will be available to me at work soon, though.... it might even be available now, I haven't worked in a few days. My son has his physical on Friday, not sure if his Drs office has it or not, I don't think any of us are getting the H1N1 shot, but we don't get any flu shots ever. I had a family member get very sick w/ a neurological disease within days of a flu shot and I have seen it happen in the hospital I work in. Unless his pediatrician can convince me, I think we will opt out.
I believe that the vaccine takes a few weeks to take effect, though, so even if you got the vaccine before you left, if you came in contact w/ the flu you could still get it, though maybe not as bad.
