A mother presents to the nurse practitioner with her 10-year-old son for a routine well check and a flu shot. She asks the NP if there are any vaccines he is not up-to-date on. The NP explains that the HPV vaccine (Gardasil 9) is indicated for which of the following groups?

Choice A reason: HPV vaccination is not limited to females; males are also recommended to receive it for prevention of HPV-related diseases. Choice B reason: While males are indicated, vaccination is not limited to them; females are also recommended. Choice C reason: While routine vaccination is ideally given at ages 11-12, catch-up vaccination is recommended through age 26, making this choice incomplete. Choice D reason: The HPV vaccine is indicated for all children and adults aged 9-26, including both genders, for both routine and catch-up vaccination.
