NCT ID NCT06366672
First seen Nov 01, 2025 · Last updated May 23, 2026 · Updated 33 times
Summary
This study looks at how long the JYNNEOS vaccine (used against smallpox and monkeypox) stays effective. Researchers will measure immune responses in the blood, lungs, skin, and bone marrow of 20 healthy adults aged 18-60 who have never had the vaccine or monkeypox before. The goal is to understand how long protection lasts, not to test a new treatment.
