The vaccine was 100 percent effective when it was tested on more than 4,000 people who were in close contact with Ebola patients in the African nation of Guinea, the World Health Organization said, citing a study published today in the Lancet medical journal. The trial of the vaccine, called Ebola ca suffit — "Ebola, that's enough" in French — began on March 23. [Bloomberg]
