HPV Vaccination for the Prevention of Cervical Intraepithelial Neoplasia

A sexually active 18-year-old woman presents to her internist for an annual examination. During the review of her family history, she notes that her mother recently received a diagnosis of pre-cervical cancer and underwent a loop electrosurgical excision procedure. The patient's mother has advised her to get the cervical-cancer shot. Should this patient receive a human papillomavirus (HPV) vaccine, and how effective would vaccination be in preventing cervical cancer?
