Longworth DL - A quadrivalent vaccine against human
papillomavirus prevents cervical intraepithelial neoplasia,
vulvar and vaginal intraepithelial neoplasia, and
anogenital disease in young women. The vaccine is likely
cost-effective when given to girls, but perhaps not when
given to boys. Although hepatitis A immune globulin is modestly better than hepatitis A vaccine for postexposure
prophylaxis against hepatitis A, both are highly effective.
