Human papillomavirus is a common sexually transmitted infection--more than half of sexually active men and women are infected with HPV at some time in their lives. But HPV vaccines can help prevent infection from both high risk HPV types that can lead to cervical cancer and low risk types that cause genital warts.
HPV vaccines are recommended for girls ages 11-12. Catch up vaccination is recommended for girls and young women ages 13-26 who have not been previously vaccinated.
Males are also at risk for a number of HPV diseases, so boys and young men ages 9-26 can also be vaccinated against HPV.
