Story summary

The World Health Organization (WHO) has approved clinical trials for two new Ebola vaccines aimed at combating the Bundibugyo strain, which has caused over 5,300 deaths, mostly in the Democratic Republic of the Congo (DRC), since May 2026. The approval comes as public health agencies struggle to contain this deadly virus due to a lack of specific vaccine or treatments; the Bundibugyo strain has a fatality rate of 50%. WHO chief Tedros Adhanom Ghebreyesus noted that while an existing trial uses the Ervebo vaccine, which is effective against the Zaire strain but not the Bundibugyo strain, these new vaccines are specifically designed to address this particular threat.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
