The HPV vaccination is a vaccine that protects people against human papilloma virus. It is currently being studied as a way to prevent oropharyngeal cancer.
One article out of the CDC (1) discussed HPV and how the HPV vaccination can protect a person from getting oropharyngeal cancer. The same kinds of HPV that infect the genitals can infect the throat and mouth. The article also indicated that HPV can cause normal cells in the oropharyngeal area to become abnormal.
The HPV vaccinations that are now available were developed for cervical cancer but there is no reason to suspect that they can’t work to prevent oropharyngeal cancer.
