Julie,
I second Lolly's comments and I, as well was in the U of W vaccination trial. They have several trials going on, this link will bring you to the web site with their study abstract noting the results of the trial Lolly and I were in...they presented this at the ASCO conference in Atlanta last month.

Good luck and let us know which one you choose...I think it is interesting to follow the different trials and see what they are reaching for.
Love Kim from CT
