First seen Mar 14, 2026 · Last updated May 09, 2026 · Updated 10 times
Summary
This study tests whether giving two live vaccines (for dengue and chikungunya) at the same time is as safe and effective as giving them separately. About 900 healthy adults aged 18 to 59 who have never been exposed to either virus will take part. The goal is to see if a single visit can protect against both mosquito-borne diseases.
