Cervical cancer is the fourth commonest cause of cancer among women, and tragically is often diagnosed too late. Cervical cancer is a type of cancer that develops in a woman's cervix (the entrance to the womb from the vagina). It is caused by the human papillomavirus (HPV) which is easily spread by sexual intercourse. Cervarix is a vaccine against certain types of cancer-causing human papillomavirus (HPV). Currently, Cervarix, which with another vaccine, Gardasil, is being rolled out to shield young people from HPV. A new study has found that a single vaccine shot, rather than the recommended triple dose, may be enough to protect women against cervical cancer. The new research is published in the The Lancet Oncology.
