Hi Gail! So if I understand correctly the idea is to vaccinate for HPV16 only in the hopes that that will possibly stop a reccurence in the future or "new" scc caused by the virus? What about hpv18 & all the others? I'm sort of thinking/pondering outloud here. I'm going to have to do a whole lot more reading I can tell. Thank you for the post & have a wonderful time with your trip! Have as much fun as possible & push the envelope! Erik
