Ebola vaccine immunity under the microscope: how long does protection last?
NCT ID NCT05313139
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how long the Ebola vaccine (rVSV-ZEBOV) protects health workers in the Democratic Republic of the Congo. Researchers measured immune cells and antibodies in 133 vaccinated health workers to see if protection lasts beyond 1-2 years. The goal is to understand if booster shots are needed, especially after recent Ebola cases in previously vaccinated people.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
rVSV-ZEBOV vaccine
What this could lead to
If successful, this could show how long the Ebola vaccine protects health workers and whether booster doses are needed.
What could go wrong
This is an observational study, not a treatment trial. It only measures immune responses and cannot prove the vaccine prevents future infections.
