title: Human papillomavirus vaccine: a paradigm shift for pediatricians.
abstract: OBJECTIVE
  Recommendations for human papillomavirus (HPV) vaccination during adolescence primarily for a disease, cancer, that occurs only during adulthood is a paradigm shift for pediatricians. Additional postlicensure data and guidelines about HPV biology and epidemiology, disease association, adverse effects, vaccination during pregnancy, and cost-benefit analyses are now available to inform pediatricians and guide HPV vaccination recommendations.
  
  
  RESULTS
  The prespecified, end-of-study combined analysis of HPV vaccine efficacy studies for prevention of cervical cancer, and now also for prevention of vulvar and vaginal cancers, confirmed 98-100% vaccine efficacy. Postlicensure surveillance identified a new association of vaccine administration with syncope, and provides assurance of the safety of inadvertent vaccination during pregnancy. Several cost-effectiveness analyses consistently demonstrated that HPV vaccination of 12-year-old girls and catch-up vaccination through 18 years of age, and possibly to 26 years of age, is cost-effective, although the thresholds of affordability vary by study. The downward trend in age of initial HPV infection and the need to educate parents and patients about HPV disease and vaccination underscore the essential role of pediatricians in managing HPV illness.
  
  
  CONCLUSIONS
  It is critical for pediatricians to thoroughly understand HPV biology and disease and champion HPV vaccination to prevent cervical, vulvar, and vaginal cancers, even though these benefits accrue during adulthood and will likely require 2-4 decades to realize the financial and public health benefits. Several new developments are expected in the near future, including licensure for use in boys and men and the approval of a second, bivalent HPV vaccine.
