Correct answer: C — Do not administer another RSV vaccine this season

The best answer is “Do not administer another RSV vaccine this season”. Age qualifies him, but prior receipt already completes the current one-dose recommendation. CDC recommends one RSV vaccine dose for everyone 75 or older and adults 50–74 at increased risk; it is not currently annual and prior recipients should not be revaccinated. The alternatives use a different threshold, timing, population, or intervention and therefore do not match the clinical facts presented.
