A new study looking at the prevalence of human papillomavirus (HPV) infections in girls and women before and after the U.S. introduction of the HPV vaccine shows a significant reduction in vaccine-type HPV in U.S. teens. Since the vaccine was introduced in 2006, vaccine-type HPV prevalence has decreased 56% among female teens ages 14-19, data indicate.

  • Public health officials are advocating HPV vaccination. Only one-third of girls aged 13-17 have been fully vaccinated with HPV vaccine.
  • About 79 million Americans, most in their late teens and early 20s, are infected with HPV. Each year, about 14 million people become newly infected.
