James Harrison; The Austrialian Man that have saved Millions of Baby. He has helped save the lives of more than 2 million babies by donating his “special” blood, which was used to make a medication that can prevent life-threatening problems in newborns.

But why exactly is this man’s blood special, and how does the medication work to save babies?
James Christopher Harrison (born 27 December 1936), also known as the Man with the golden arm, is a blood plasma donor whose unusual plasma composition has been used to make a treatment for Rhesus disease.

Harrison started donating in 1954 and after the first few donations it was discovered that his blood contained unusually strong and persistent antibodies against the D Rh group antigen.
