This document summarizes research finding that HPV vaccines are reducing infections and disease. An analysis of 66 million people found plummeting rates of genital warts and precancers after HPV vaccination. A major new study across multiple countries found that HPV vaccines have reduced infections and precancers in girls and women, providing evidence they will ultimately lower cervical cancer rates. The vaccines were also found to provide some protection to unvaccinated boys and older women. However, vaccination rates remain below targets in some areas.
