HPV vaccines are given as a series of three shots over 6 months to protect against HPV infection and the health problems that HPV infection can cause. Two vaccines (Cervarix and Gardasil) protect against cervical cancers in women. One vaccine (Gardasil) also protects against genital warts and cancers of the anus, vagina and vulva. Both vaccines are available for females. Only Gardasil is available for males.
HPV vaccines offer the best protection to girls and boys who receive all three vaccine doses and have time to develop an immune response before being sexually active with another person. That's why HPV vaccination is recommended for preteen girls and boys at age 11 or 12 years.
Who else should get the HPV vaccine?
In addition to girls and boys aged 11 or 12 years, HPV vaccines are also recommended for teen boys and girls who did not get the vaccine when they were younger, teen girls and young women through age 26, as well as teen boys and young men through age 21.
The vaccine is also recommended for gay and bisexual men (or any man who has sex with a man). It is also recommended for men and women with compromised immune systems (including people living with HIV/AIDS) through age 26, if they did not get fully vaccinated when they were younger.
