Context

A vaccine trial against the Bundibugyo species of Ebola has started in Bunia, eastern DRC, where most cases and deaths in the current outbreak have occurred. The first vaccine used is Merck's Ervebo, approved for the Zaire species; researchers will assess cross-protection.

Candidates specific to Bundibugyo from Moderna and Oxford/Serum Institute could be added within weeks. The WHO reported 9,704 confirmed cases and 4,687 deaths in the DRC as of October 20.

Conflicting Reports

  • Case and death figures: Al Jazeera reports 'more than 9,700' cases and 'more than 4,600' deaths; SCMP cites WHO figures of 9,704 cases and 4,687 deaths as of October 20. These are consistent, not conflicting.
