Is he now immune to Eboli? Can they use his blood for a serum?
Perhaps, but active Ebola virii have been found in certain body fluids up to 61 days after recovery.
From what I’ve read the survivors do tend to have anti-bodies but I don’t think I’ve ever read that they are immune. They are using survivors blood serum for the anti-bodies but its not a cure.
If I recall correctly the woman received a serum from one of the other survivors.
As I recall, Dr. Brantly received blood from a boy who’d recovered from Ebola under his care. I wondered at the time if there was an immunity factor involved.
