How Ebola survivors’ blood is saving lives

William Pooley, the British nurse who successfully recovered from the Ebola virus, has returned to work in West Africa.

Subsequent patients, including Spanish nurse Teresa Romero, have been treated with blood from Ebola survivors.

It is believed that they may have some immunity to the virus.

More than 4,500 people have died from Ebola, mainly in Guinea, Liberia and Sierra Leone.
