One of the most deadly sexually transmitted infections is the human papilloma virus (HPV). Virtually all cervical cancer cases are linked to genital infection with the virus. Cancer of the cervix is the second most common cancer in women, with about 500 000 new cases and 250 000 deaths each year. The new vaccine that prevents the infection could reduce these cervical cancer-related deaths.
