Answer: a.
Rationale: CDC recommends the VLP chikungunya vaccine for adults (≥18 years) who are at increased risk for infection or severe disease — for example older adults and persons with underlying medical conditions, and those with prolonged or frequent exposure to mosquito vectors or travel to areas with CHIKV transmission. Choice (a) is a 70‑year‑old with comorbidities and a 6‑month exposure period, which fits CDC priority groups.
(b) is a short (2‑week) trip by a healthy person to a place without current transmission, (c) is under age 18, and (d) is a healthy 50‑year‑old (not clearly at high risk) — so (a) is the best match.
