Thanks for posting the specifics Brian.

If I am reading right, although it is premature to speculate, and there may be unknown variables involved, a few points to me show promise:

-women who already had 1 bout of HPV disease (assumes they are HPV+)
-some type of protective immune response is occurring against future HPV disease (if not validated for recurrent SCC at this point, at least precancerous disease)
-it induces a response beyond the 4 subtypes (the response is robust and generalized)
-the response is being exhibited beyond the cervix and in other parts of the female anatomy (perhaps effective in other areas of the body with squamous cells)

The $500+ question still begs statistical significance for those who had treatment for HPV-related cancer, reproductive SCC and oral SCC.
