Which age group is appropriate to receive the 2-dose HPV9 vaccine series?

The correct selection is based on the CDC recommendations, which state that the HPV vaccine series is ideally administered to preteens, starting at 11 to 12 years of age. The vaccination can begin as early as 9 years of age, allowing for protection before the onset of sexual activity. For those who start the series between 9 and 14 years of age, a 2-dose series is recommended, with the second dose given 6 to 12 months after the first.

This approach is aimed at maximizing immune response and ensuring adequate protection from HPV-related diseases, including cervical cancer, anal cancer, and other HPV-associated conditions. Typically, individuals over the age of 15 require a 3-dose series, which underscores the importance of early vaccination. Therefore, the age range of 9 through 14 years is specifically aligned with educational initiatives encouraging vaccination before the age of 15, leading to an effective and simplified scheduling process for the immunization series.
