The Man with the Golden Arm

This podcast episode of "Stuff You Should Know" features Josh and Chuck discussing James Harrison, an Australian man known as "the man with the golden arm" for donating blood plasma over 1,000 times, which was used to create anti-D immunoglobulin. This immunoglobulin prevents Rhesus disease, a condition where a pregnant person's immune system attacks the red blood cells of their fetus. They detail the history of understanding Rh incompatibility, the development of the anti-D treatment, and Harrison's extraordinary dedication to blood donation, which is estimated to have saved 2.4 million babies. They also discuss the need for more blood donors, particularly in the United States, and share a listener email correcting a previous episode.
