Explanation / Answer

The vaccines prevent infection with HPV types 16 and 18, two high risk HPVs which cause about 70% of cervical cancer. Gardasil prevents infection with HPV types 6 and 11 which cause 90% of genital warts.

Protection from HPV vaccine is expected to be long lasting. But vaccinated women still need cervical cancer screening because the vaccine doesn't against all HPV types that cause cervical cancer.

HPV cancers prevent infection by certain types of human papillomavirus. Available vaccines protect against either 2, 4 or 9 types of HPV.

* a bivalent
