Why is HPV vaccination recommended before exposure to HPV, and what is the typical target age range?

• A. To maximize prevention of infection before sexual activity; typical target age 11-12 with catch-up to 26-45.
• B. To treat existing HPV infection; typical target 30-50.
• C. To prevent HPV in infants; 0-2.
• D. To replace regular cervical screening; 40-60.

Answer: (C)

HPV vaccination is most effective when given before exposure to the virus because it teaches the immune system to recognize and neutralize multiple HPV types before any infection has occurred. If someone is already exposed or infected, the vaccine can’t clear those existing infections, so protection is maximized by vaccinating prior to sexual activity.

The typical target age is around 11 to 12 years old, with catch-up vaccination offered through age 26. In some guidelines, vaccination may be extended for certain individuals up to age 45, depending on risk and vaccine type. This program aims to prevent HPV-related cancers and conditions by providing immunity before exposure.

It’s important to note that the vaccine is for prevention, not treatment, and it does not replace regular cervical cancer screening.
