Need for HPV Vaccination Likely to Be Eclipsed by Other Developments
On average, HPV infections take 20 years to develop into cancers. With the rate of current medical progress, it is quite probable that a vaccine to cure cervical cancer will be ready for clinical trials in five to ten years. Hence, it is reasonable to hesitate in the face of rapidly advancing medical developments and not vaccinate now for an illness that in all likelihood won’t manifest for another 20 years.

Something might turn up in the next century, but the vaccine is here, now. A vaccine in the arm is worth ten in the "may turn up" category.
