At what age can routine vaccination with HPV vaccine begin according to ACIP recommendations?

Routine vaccination with the HPV vaccine can begin at 9 years old according to the ACIP recommendations. This early initiation is designed to ensure that children are protected before they become sexually active, which is the primary mode of transmission for the human papillomavirus. Vaccination at this age allows for a wider range of coverage and increases the likelihood of establishing immunity before exposure to HPV occurs.

The ACIP recommends a two-dose schedule for those who start the series between ages 9 and 14, making it essential to offer the vaccine at this younger age when the immune response is typically more robust. The recommendation aligns with the overall goal of public health to reduce the incidence of HPV-related diseases, including certain cancers, by encouraging vaccination at a younger age.

Later ages for routine vaccination, such as 11, 13, or 15 years, while still beneficial, do not reflect the urgency and effectiveness of starting vaccination at 9 years old, which is considered the optimal time for administration according to these guidelines.
