Spoken like someone not in the medical field.

There are already vaccines for cervical cancer.

And oh, that cervical cancer vaccine is widely available and in fact the US actually passed a law stating insurance has to pay 100% of the vaccine to all eligible patients. If you don't have insurance, the US government will pay for it anyways.

India recently launched their version of the cervical cancer vaccine that they were able to make significantly cheaper per person ($2-5).

There is also a vaccine for melanoma as well. Although it's less common these days because we have better and newer treatment options for melanoma (immunotherapy).
