Ebola vaccine memory under the microscope: how long does it last?
NCT ID NCT06100913
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study gives 30 healthy adults a single dose of the approved Ebola vaccine (Ervebo) and tracks their immune responses over time using blood, lymph node, and bone marrow samples. The goal is to understand how long the body 'remembers' the vaccine, which could guide future booster schedules. It is not testing the vaccine's effectiveness against Ebola, but rather the durability of immune memory.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Ebola vaccine (Ervebo)
What this could lead to
If successful, this could help determine how often booster shots are needed to maintain protection against Ebola.
What could go wrong
This is a small, early-phase study focused on immune response, not on preventing disease. Results may not predict real-world protection.
