The Centers for Disease Control and Prevention now recommends that all boys and girls aged 11 or 12 receive the shots. Vaccination campaigns, aimed largely at girls and women, have fallen short of expectations. By 2013 just over half of U.S. females aged 13 to 17 had received at least one dose of either the Gardasil or Cervarix vaccine. For males, that figure was a disappointing 35 percent. Now head and neck cancers associated with the virus are on the rise, leading some experts to recommend that a gender-neutral or male-centric approach might be more effective. HPV is the most prevalent sexually transmitted disease in the U.S. and worldwide, infecting just about all men and women at some point in their lives. Although most people clear the virus naturally, persistent infections with some strains can lead to cancer—usually cervical or oropharyngeal (affecting the back of the throat, tonsils and back of the tongue). HPV-associated cancers make up 3.3 percent of all cancer cases among women and 2 percent of all such cases among men annually in the latest available figures, yet the incidence of virally instigated oropharyngeal and anal cancers is increasing.
