According to a recent study, a quadrivalent Human Papillomavirus (HPV) vaccine is effective in preventing high-grade vulval and vaginal lesions that can lead to cancers in those areas.

Vaccine efficacy varied from 71% in women previously exposed to the human papillomaviruses to 100% in those not previously exposed. Additionally, a 49% reduction in all high-grade vulval and vaginal lesions, irrespective of casual HPV type, was seen in the intention-to-treat population of sexually active young women

The study has been published in this week's issue of The Lancet.
