Transfusing the blood or blood plasma of ebola survivors is actually a (somewhat experimental) method being used as a treatment for ebola.

The theory is, since ebola survivors have antibodies in their blood which fight the virus, transfusing their blood into the blood stream of someone who is currently suffering from ebola can give them a kind of "temporary immunity", which gives their immune system a bit of a head-start on figuring out how to fight the disease for itself.
