It is actually a vaccine for different types of papillomaviruses (HPV). There is over 120 types of HPVs but most of them are benign. Under 20 of these papillomavirustypes are considered high risk and could cause intraepithelial lesions that may lead to cervical cancer. Most of new cervical cancers are attributable to

high-risk HPVs, making HPV one of the most important infectious cause of cancer. The vaccine prevents from the most common high-risk HPVs which cause over 90% of all genital warts and most of the HPV associated cancer caces.
