Development and Impact of Human Papillomavirus VaccinesDARUS, CHRISTOPHER J. MD; MUELLER, JENNIFER J. MDClinical Obstetrics & Gynecology: March 2013 - Volume 56 - Issue 1 - p 10–16 doi: 10.1097/GRF.0b013e31827af770 Screening Tests for Cervical Cancer Abstract Author Information Cervical cancer is a global health crisis that disproportionately affects developing nations and underserved populations. Two vaccines targeting HPV-16 and 18, which account for 70% of invasive cervical carcinomas, are licensed in the United States and numerous countries worldwide. Both vaccine formulations have shown excellent efficacy with minimal toxicity. Numerous questions remain, including cost-effectiveness, vaccination of males, societal acceptance of HPV vaccination, and cervical dysplasia screening in the HPV-immunized population. Access to vaccination for underserved populations both in developed and resource-poor nations remains an issue. Multivalent vaccines that encompass additional oncogenic HPV strains are under development.
