Can the blood of Ebola survivors create a cure?

For months, Vanderbilt University researcher Dr. James Crowe has been desperately seeking access to the blood of U.S. Ebola survivors, hoping to extract the proteins that helped them overcome the deadly virus for use in new, potent drugs.

His efforts finally paid off in mid-November with a donation from Dr. Rick Sacra, a University of Massachusetts physician who contracted Ebola while working in Liberia. The donation puts Crowe at the forefront of a new model for fighting the virus, now responsible for the worst known outbreak in West Africa that has killed nearly 7,000 people.
