The lesson here is if you got a mouth, butt, or crotch, get the HPV vaccine. Got kids? They can get the vaccine at 11 or 12. Vaccinate them as young as you can.
Got a doctor that won’t let you vaccinate your kids at that age - refer them to the CDC, and if they still refuse, get a different doctor.
When I got mine about 10 years ago, the process was that you get three shots spaced a month apart.
