Experimental vaccines for the Bundibugyo strain of Ebola, effective against the current outbreak in the Democratic Republic of Congo and Uganda, have been stored in freezers in Winnipeg and Texas for years. Researchers, including Canadian microbiologist Gary Kobinger, express frustration over the delay in clinical trials. While vaccines exist for the Zaire strain of Ebola, none are approved for Bundibugyo, despite promising lab results. The situation highlights gaps in prioritizing research for less common Ebola strains.

The international health community is accelerating efforts to develop vaccines for the Bundibugyo Ebola strain, which has no approved treatment and has spread across the Democratic Republic of Congo and Uganda. Recent developments include Russia's announcement of a ready vaccine candidate and revelations about existing experimental vaccines stored in Canada and the U.S. The outbreak has prompted urgent action from global health authorities, with the WHO maintaining its international health alert status as cases continue to rise.
