The potential benefits of vaccines are twofold: In addition to directly protecting those who get the vaccine, they also protect those who don’t. The latter, a phenomenon called herd immunity, occurs as more and more people get vaccinated, further restricting the ease with which the disease-causing germ can spread.

Now a new study suggests that the human papillomavirus (HPV) vaccine may be providing men with herd immunity against HPV infections of the throat. Oral HPV infections cause over 70% of all oropharyngeal cancers in the United States, and rates of these cancers in men have skyrocketed over the past several decades.
