"Sanofi Pasteur -- the Merck- and Sanofi Aventis-owned vaccine producer -- on Wednesday announced that an analysis of a Phase II clinical trial of the company's experimental human papillomavirus vaccine Gardasil shows that it is effective in preventing cervical neoplasia and external lesions for five years, AFX/Euro2day reports (AFX/Euro2day, 4/26). Merck in October 2005 announced that Gardasil in clinical trials was 100% effective in preventing infection with HPV strains 16 and 18, which together cause about 70% of cervical cancer cases."

Cancer-causing, even rarely, is not relatively harmless.
Gardasil at best, might help 50%, the other 50% will die because of a false sense of security.
I can bet you money that you wouldn't go to a malaria infested part of Africa vaccinated with a vaccine that only protects you from 2 strains of the virus carried by mosquito's which make up only 2% of the species variety. Again, this does NOT warrant manditory vaccination, and the reasons are numerous. PAY FOR IT YOURSELF.
You miss the point -- if the disease protected against is rare, then the vaccine can easily be worse than the disease it cures if given to large populations.
