New mpox vaccine trial launches in DRC: could it be a game changer?

NCT ID NCT07253675

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This Phase 2 study will test a new mpox vaccine called MVA-SIBP in 180 people aged 2 to 45 in Kinshasa, DRC. Participants will receive two doses of either a low or high dose of the new vaccine, or a licensed vaccine (MVA-BN) for comparison. The goal is to check safety and how well the vaccine triggers an immune response against mpox.

What this could mean

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

Active substance

MVA-SIBP vaccine (low and high dose) compared to MVA-BN vaccine

What this could lead to

If successful, this could provide a new, locally produced mpox vaccine for use in the Democratic Republic of the Congo and other affected regions.

What could go wrong

This is a Phase 2 trial with only 180 participants, so results may not apply to larger populations. The vaccine may not produce strong enough immunity or could cause unexpected side effects.
