The vaccine against human papillomavirus (HPV) infection, which doctors believe causes most cases of cervical cancer, appears even more effective than believed, a new study finds.
"After eight years of vaccination, the reduction in the incidence of cervical neoplasia [abnormal growth of cells], including pre-cancers, have been reduced approximately 50 percent. This is greater than what was expected -- that's pretty exciting," said lead researcher Cosette Wheeler.
