For adults with incomplete HPV immunization, what catch-up vaccination age range is recommended?

• A. 9 to 14
• B. 27 to 45
• C. 15 to 26
• D. 50 to 65

Answer: (B)

Catch-up HPV vaccination is considered for adults aged 27 through 45 who have not completed the series. Routine vaccination is recommended up to age 26, but in this older age group, vaccination may still be offered after a discussion between clinician and patient to weigh potential benefits against prior HPV exposure. The chance of benefit decreases with age, since many people have already been exposed to HPV, but vaccines can still protect against types the person has not encountered. Therefore, 27 through 45 is the appropriate catch-up window because it targets adults who missed vaccination earlier while still allowing for individualized decisions about potential protection.
