Ebola vaccine induces T cell cross-reactivity against Bundibugyo virus in humans

The current Ebola outbreak in the Democratic Republic of the Congo, caused by the Bundibugyo Ebola virus (BDBV), is the second largest Ebola outbreak worldwide. While there is currently no approved BDBV vaccine, a study finds that the existing Ebola vaccine induces T cell cross-reactivity against BDBV in humans, potentially providing some level of protection.
