One man's plasma protected 2.4 million babies

James Harrison had a lot of transfusions after lung surgery at 14. As an adult his RhD-negative blood carried rare anti-D antibodies. He donated more than 1,100 times between 1954 and 2018. His plasma helped make about 2.4 million doses of anti-D, which is given to RhD-negative mothers to prevent haemolytic disease of the fetus and newborn. He helped make Australia the first country to supply all its own anti-D.
