A vaccine to prevent cervical cancer, triggered by the human papillomavirus (HPV), has helped reduce the number of teenage girls developing abnormalities in their cervix by as much as 50 percent in a study in Australia, researchers reported on Friday. Some strains of HPV are known to cause abnormal lesions in the cervix, which may turn cancerous later on. Vaccines are aimed mainly at girls between the ages of nine and 12 as they are regarded as most effective when given before the onset of sexual activity.
