Quick Summary

Doctors Without Borders is calling on global health officials to increase access to the Ebola vaccine Ervebo in response to its potential effectiveness against a different strain of the virus. In the Democratic Republic of Congo, more than 5,300 people have died from the Bundibugyo strain, which currently lacks a specific vaccine. Although DR Congo requested 500,000 doses of Ervebo, only 70,000 were approved for distribution due to limited evidence of its efficacy against this particular strain. The organization argues that early data showing fewer cases and deaths among vaccinated individuals supports expanding the use of Ervebo beyond current restrictions set by the World Health Organization.

Story summary

Doctors Without Borders (MSF) has urged global health officials to expand access to Ervebo, an Ebola vaccine developed by Merck for a different strain, in response to the ongoing Bundibugyo outbreak in DR Congo. The charity claims that early observations suggest Ervebo may provide some protection against the Bundibugyo strain despite it not being its intended target. More than 5,300 people have died from this strain in what is described as DR Congo's largest-ever Ebola outbreak.

MSF argues that more at-risk individuals, including young children, should be vaccinated with Ervebo but notes that only 70,000 doses out of the requested 500,000 doses have been released due to limitations set by the World Health Organization (WHO). The WHO currently recommends restricting its use against Bundibugyo for research purposes alone as the vaccine’s efficacy remains unproven. MSF believes that justifying wider distribution will require backing from the WHO's vaccine advisory committee, which convenes next week.
