Well, the thing is that there isn't really a high risk category for contracting HPV. It's not even always sexually transmitted. You can pick up the virus just by touching something that's been touched by someone with the virus. Being part of a high risk category and contracting a high risk strain are very different things. The high risk strains are strains of the virus that are more likely to develop into cervical cancer.
They're now vaccinating younger girls against certain strains of HPV and there is a vaccine in development for boys as well. It would be nice to have more general access to the vaccine for all adults.
