On Thursday, officials at the National Institutes of Health announced that they were launching safety trials on a preliminary vaccine for Ebola. Researchers have already checked that still-not-tested vaccine against some of the more than 350 mutations in this strain of Ebola to make sure the changes the disease is making won’t undercut science’s hurried efforts to fight it, said Pardis Sabeti, a scientist at Harvard University and its affiliated Broad Institute. She and Gire, also at Broad and Harvard, are two of the lead authors of a study published Thursday in the journal Science that maps the killer disease strain based on specimens collected from 78 patients.
