I think it was an exciting new opportunity to prevent cervical cancer in kids, young girls. I think we lost sight a little bit of the fact that we didn't have a post-vaccine surveillance program in place. I think that was a terrible shame, that in fact the medication was funded without any follow-up, especially in young girls. Who knows what's going to happen?
Fortunately, vaccines by and large tend to be safe, although we've just been through this whole issue of vaccines and autism, as being a potential trigger for autism, and we really don't know the answer to the question.
