It's a virus that causes genital warts and cancer of the cervix. Each year, scores of women are diagnosed with the cancer because they unaware of being infected with HPV. A virus that most people are unaware they have.
But now researchers have develop a vaccine they say kills its viral culprit, "We don't get rid of the virus, we just destroy the affected cells from developing," tells Dr. Brown.
