WHO recommends the human papillomavirus (HPV) vaccine for girls in the age group of 9–13 years. Girls receiving a first dose of HPV vaccine before the age of 15 years can use a two-dose schedule. The interval between the two doses should be six months. There is no maximum interval between the two doses; however, an interval of no greater than 12–15 months is suggested. If the interval between doses is shorter than five months, then a third dose should be given at least six months after the first dose. Immunocompromised individuals, including those who are living with HIV, and females aged 15 years and older should also receive the vaccine and need three doses (at 0, 1–2, and 6 months) to be fully protected.
