Doctor Kevin Brantley survived Ebola. One possible cause for his recovery? A blood transfusion from a young Ebola survivor in Africa.Blood transfusions are an experimental treatment for Ebola.Survivors may have high levels of antibodies in their blood that can help fight the Ebola virus in new patients.Brantley has donated blood or plasma to three U.S. Ebola patients.He was not able to donate to Thomas Duncan, the Liberian who died of the virus at a Dallas hospital, because they did not share the same blood type.Blood transfusions share some similarities with vaccines now in development that use artificial antibodies similar to the ones found in survivor blood.Dr. Jesse Goodman, a professor of medicine and infectious diseases at Georgetown University Medical Centersays the medical community still needs more research on the effectiveness of the transfusions.“We do not know whether transfusion of blood from somebody who has recovered from the disease actually helps.We do not know. So the fact that some individuals who receive the blood get better does not necessarily mean that it is the blood that did it,” said Goodman.Goodman said that the transfusions may be only one element in the treatment of Ebola survivors.Prompt medical attention and the overall health of the patient are also factors in recovery from the virus.The transfusion treatment will need to undergo rigorous testing to determine if it makes a difference.
