Vaccine reduces cervical-cancer virus' prevalence in teenage girls by almost 65%

New York

A VACCINE introduced a decade ago to combat the sexually transmitted virus that causes cervical cancer has already reduced the virus' prevalence in teenage girls by almost two-thirds, federal researchers said on Monday.

Even for women in their early 20s, a group with lower vaccination rates, the most dangerous strains of human papillomavirus (HPV) have still been reduced by more than a third.
