Experimental Ebola serum may have saved two infected American doctors

A top secret, highly experimental serum that was rushed to two Ebola-stricken American doctors in Liberia appears to be working, CNN's Dr. Sanjay Gupta reported Monday.

The treatment — known as ZMapp — is derived from the antibodies produced by three separate mice who were exposed to different fragments of the Ebola virus. Before being stored at subzero temperatures and flown to Liberia, ZMapp had only been tried on a small group of monkeys — hardly the ideal testing process before being administered to humans. But in a highly unusual move, the National Institutes of Health cut through red tape and fast-tracked delivery of the serum to Drs. Kent Brantly and Nancy Writebol in Liberia when both tested positive for the virus.
