Two doses of the HPV vaccine are recommended for all boys and girls at ages 9-12; If you wait until they’re older, they may need three doses instead of two. Children who start the vaccine series on or after their 15th birthday need three shots given over 6 months. If your teen hasn’t gotten the vaccine yet, talk to his/her doctor about getting it as soon as possible. HPV vaccination is also recommended for everyone through age 26 years, if not vaccinated already. Vaccination is not recommended for everyone older than age 26 years. However, some adults age 27 through 45 years who are not already vaccinated may decide to get HPV vaccine after speaking with their doctor about their risk for new HPV infections and the possible benefits of vaccination. HPV vaccination in this age range provides less benefit, as more people have already been exposed to HPV.
