James Christopher Harrison, an 87-year-old Australian, has made a remarkable impact by helping over 2.4 million babies through his blood donations. His journey began at age 14 when he required a life-saving blood transfusion. By 18, in 1954, he started donating blood to give back for the help he received. It wasn’t long before doctors discovered his blood contained a unique antibody.

Harrison’s plasma is rich in a powerful antibody known as Anti-D, which is crucial in creating a special treatment for Rhesus D Haemolytic Disease (HDN). This condition can lead to miscarriages, stillbirths, and severe complications in newborns. Before the 1960s breakthrough, HDN caused the deaths of thousands of Australian babies annually. The discovery that injecting Rh-negative mothers with RhD immunoglobulin could prevent HDN by neutralizing any Rh-positive blood cells was a game-changer.

Over his 60-year donation career, Harrison made 1,173 donations. He made his final donation at age 81, ending an extraordinary chapter in his life. His rare blood type combination has earned him the nickname “the man with the golden arm,” as his plasma is a vital source of life-saving treatment. When Australian scientists were searching for a solution to HDN, Harrison’s blood became the cornerstone of the Anti-D program, with his plasma contributing to every Anti-D treatment made in Australia.

Harrison’s commitment didn’t wane even when he reached the retirement age for donors. He continued to donate weekly, amassing 1,162 donations from his right arm and 10 from his left, demonstrating unmatched dedication.

Given that over 17% of Australian women face the risk of HDN, Harrison’s contributions have been essential. Take baby Samuel, who is now just five weeks old. His mother, Kristy Pastor, received the Anti-D injection during her second pregnancy, thanks to Harrison’s antibodies. Kristy deeply appreciates Harrison’s selflessness, recognizing how his donations help ensure that mothers like her can access this vital treatment to protect their babies’ health.
