Blood Donor with Rare Blood Type Saved Millions of Australian Kids, Dead at 88

James Harrison's rare blood, which he donated over a thousand times, is estimated to have saved the lives of over 2 million children in Australia. Harrison carried a rare antibody in his plasma known as anti-D. Our red blood cells can carry a certain protein on their surface known as rhesus (RhD). When a pregnant woman with RhD-negative blood is sensitized to RhD-positive blood cells (this usually happens during a previous pregnancy), her body can create antibodies that attack and harm her RhD-positive fetus—a condition called Rhesus disease. But a dose of anti-D given proactively to mothers at risk of Rhesus disease can prevent it from happening in the first place. Tap our link in bio for more on this story.
