Which action by a parent of a school age child indicates understanding of the vaccination protocol to prevent cervical cancer?

A. Client received first vaccination at 8 years of age is incorrect because the human papillomavirus (HPV) vaccine is typically recommended starting at ages 11–12. Although vaccination can begin as early as 9 years in some cases, initiating it at 8 is not standard protocol. B. Had bloodwork obtained for titers is incorrect because HPV vaccination does not require titer monitoring. Immunity is assessed through the vaccine schedule itself, not through antibody testing. C. All three vaccinations were received at intervals is correct. The HPV vaccination series for children requires multiple doses given at specific intervals to ensure full immunity. For children starting the series at ages 11–12, two doses spaced 6–12 months apart may be sufficient, while older adolescents may require three doses. Completing the series at the recommended intervals ensures optimal protection against cervical cancer and other HPV-related diseases. D. Client received booster dose at 16 years of age is incorrect because there is no routine booster recommended at age 16 if the series was completed according to schedule. The primary goal is completing the recommended dose series at the appropriate intervals.
