Cervical cancer vaccine development.

Cervical cancer is initiated by infection of cervical epithelium with human papillomavirus. Vaccines have been developed, incorporating papillomavirus viral capsids and alum based adjuvants. In extensive clinical trials these vaccines have been shown safe and effective in preventing infection with, and disease caused by, the papillomavirus genotypes they incorporate, in women not already infected. These vaccines have the potential to reduce the global burden of cervical cancer by up to 70%.
