I wouldn't get it. (But then I haven't had any immunisations, so why start now )
I actually had swine flu a few weeks ago and then my boss caught it after me, yes it sucks but it wasn't THAT bad, no so bad that I would support any of my family being given an unknown vaccine.
I think instead of the vaccine your better off washing you hands often and steering clear of large crowds where you might contract it. (like eating in a food Court at a shopping centre)

In my opinion most people wont catch swine flu, but having the vaccine will definitely expose an unborn bubba to it.
