Summary

This study tests a two-dose Ebola vaccine regimen in healthcare workers in the Democratic Republic of the Congo, who are at high risk during outbreaks. Participants receive an initial shot of Ad26.ZEBOV followed by a booster of MVA-BN-Filo 56 days later. Some will also get an additional booster at one or two years. The goal is to measure the immune response and monitor safety.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a two-dose Ebola vaccine regimen: Ad26.ZEBOV followed by MVA-BN-Filo, with a possible booster of Ad26.ZEBOV at 1 or 2 years
What this could lead to
If successful, this vaccine regimen could help protect healthcare workers against Ebola, reducing the risk of outbreaks spreading in high-risk areas.
What could go wrong
This is a phase 2 study, so the vaccine's effectiveness and long-term safety are still being evaluated. The immune response may not be strong enough to prevent infection, and side effects are possible.
