First-ever cancer vaccine approved by FDA

The vaccine, Gardasil, blocks infection by two types of the human papillomavirus, or HPV, which account for about 70% of cervical cancer cases.
Gardasil also blocks infection by two other HPV types that cause about 90% of genital warts cases. Spread by skin-to-skin contact, HPV is the most common sexually transmitted infection in the USA. More than 90% of cases clear up on their own, but persistent infection with certain HPV types causes virtually all cervical cancers.
