There are no licensed vaccines against Bundibugyo virus, the filovirus driving the Ebola outbreak in Congo and Uganda.Using serum samples from children and adults who took part in a randomized trial of vaccines for Zaire Ebola virus disease, cross-reactive antibody responses against Bundibugyo virus were detected at 28 days and 3 months.The findings "support the evaluation of readily available Ebola vaccines during the current outbreak," researchers said.

An available vaccine for Ebola might provide partial protection against the ongoing outbreak of Bundibugyo virus, which has no licensed vaccines or therapeutics, according to new research.
