It’s not a vaccine for cancer.
It doesn’t actually do anything for cervical cancer.
What it is, is a vaccine for certain strains of HPV, which is a virus, which you can completely avoid through not having sex with people who are infected. There are many other ways to contract cervical cancer...
It is a vaccine for strains of a virus known to cause cancer. HPV is primarily sexually transmitted, but has been found under fingernails, indicating that it might also be passed by touching. And there aren’t “many other ways” to cervical cancer, most are caused by HPV, like 99%.
Like others, you are distracted by the sexual component in the whole flap. Perry was busy stealing MA’s top cancer researcher for TX new research center, that’s what motivated him to do the Gardasil thing, to make Tx appear friendlier and cutting edge to the bio-medical research community.
...the worldwide HPV prevalence in cervical carcinomas is 99.7 per cent. The presence of HPV in virtually all cervical cancers implies the highest worldwide attributable fraction so far reported for a specific cause of any major human cancer.

Now they have a vaccine for it. Which makes it an anti-cancer vaccine. Someday, other viruses will be identified in other specific cancers and they’ll develop vaccines for them as well.
