Introduction: Safety and efficacy of prophylactic HPV vaccines against HPV infection and associated cervical cancers and precursors is well documented in the literature; however, their efficacy against vulval and vaginal endpoints has not been previously assessed. Areas covered: Published results of trials involving licensed HPV vaccines were included. Main efficacy outcomes were histologically confirmed high-grade vulval and vaginal precancer distinguishing those associated with vaccine HPV types and any vulval and vaginal precancerous lesions. Exposure groups included women aged 15-26 or 24-45 years being initially negative for high-risk HPV (hrHPV), negative for the HPV vaccine types, and women unselected by HPV status. Expert opinion: Our results show that the HPV vaccines are equally highly efficacious against vulval/vaginal disease as previously noted for cervical disease. The vaccines demonstrated excellent protection against high-grade vulval and vaginal lesions caused by vaccine-related HPV types among young women who were not initially infected with hrHPV types or types included in the vaccines (vaccine efficacies more than 90%). No protection against high-grade vulval and vaginal lesions associated with HPV16/18 was observed for mid-adult women. Trials were not powered to address protection against invasive cancers VSports手机版. .
