Of 154 Ebola sufferers given Inmazeb, 33.8 % died after 28 days, in contrast with 51 % of 153 sufferers who obtained a totally different experimental antibody. Untreated, Ebola has a median fatality price of round 50 %, although fatality charges can differ broadly between outbreaks, from 25 percent to 90 percent.
