## Key points

- The current outbreak involves a strain without a licensed vaccine.
- Ervebo was developed for the Zaire strain.
- Researchers are investigating whether it could protect against other strains.

## Summary

The current Ebola outbreak in the Democratic Republic of Congo is caused by the Bundibugyo strain, for which there is no licensed vaccine or approved treatment. Researchers say this gap reflects missed opportunities to prepare after earlier outbreaks, alongside limited funding and decisions to prioritise other threats.

The existing Ervebo vaccine is licensed for the Zaire strain, not Bundibugyo or Sudan. A German research team has studied whether Ervebo can prompt immune responses to other Ebola types, raising hopes of broader protection, though vaccine effectiveness can only be confirmed during an outbreak. Bundibugyo may be less aggressive than Zaire, but infected people can remain mobile longer and spread it without realising.
