When should the HPV vaccine be typically administered?

The Human Papillomavirus (HPV) vaccine is typically administered before the age of 15 because it is most effective when given at a younger age, ideally starting between ages 11 and 12. This timing aligns with recommendations from health authorities that emphasize vaccination prior to the onset of sexual activity, as HPV is a sexually transmitted infection. Administering the vaccine at this age helps to ensure that individuals are protected before they may be exposed to the virus.

Vaccination before age 15 also allows for fewer doses; individuals who start the series between 9 and 14 years of age require only two doses, whereas those who begin the series at 15 or older require three doses. This underscores the importance of early vaccination to ensure optimal protection and adherence to dosing schedules.
