In the United States, human papillomavirus (HPV) catch-up vaccination has been nationally recommended for women and men of different ages. We surveyed national networks of primary care physicians specializing in family medicine, pediatrics, and internal medicine to assess attitudes about HPV vaccination. Of 785 physicians, 730 (93.0%), were in favor of a change to harmonize the recommended catch-up vaccination age across genders; the most commonly cited reason was to simplify the immunization schedule (97.9%). After considering these and other data, the Advisory Committee on Immunization Practices updated national policy to recommend catch-up vaccination for all persons through age 26 years.
