Earlier quoted context omitted.
The incidence of these cancers is much lower than cervical cancer. I think a more practical benefit to boys is the prevention of many strains of general warts and general herpes.
This vaccine does not prevent herpes.
The vaccine prevents against up to 9 HPV, including many genital wart [0] strains.
So I was wrong about herpes but my point was that it protects males against STIs and is just a handy vaccine to protect sexually active men against something they don’t want (some genital warts) and that seems like a greater motivator than reducing transmission to protect women from cervical cancer.
