Quick Summary

The World Health Organization announced the start of a clinical trial in Bunia, DRC, for an Ebola vaccine called Ervebo, which will test its effectiveness against the Bundibugyo strain of the virus. The trial involves a ring vaccination approach and includes two additional candidate vaccines: one from the University of Oxford and another from Moderna. Both vaccines are expected to enter the trial soon. This initiative aims to gather evidence on vaccine efficacy across various demographics, including pregnant women and children over 12 years old.

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.
