HPV causes vaginal, vulvar and anal cancers, in addition to cervical cancer, but the HPV vaccine seems to prevent these cancers as well.
Analyzing data from 2000 to 2017, Mona Saraiya, MD (above), and her colleagues found that after the HPV vaccine was introduced, high-grade vulvar precancer rates fell by 21 percent a year in females aged 15-19; high-grade vaginal precancer rates fell by 19 percent a year in females 15-29; and high-grade anal cancer rates which were increasing stabilized in females aged 15-29 and males 30-39.
