James Harrison, renowned as one of the world's most active blood donors, has died peacefully in his sleep at a nursing home in New South Wales, Australia, at the age of 88. His family announced his passing on February 17. Harrison, famously referred to as the "man with the golden arm," was celebrated for his unique blood plasma, rich in a rare antibody known as Anti-D. This antibody has been pivotal in creating the life-saving medication administered to pregnant women whose blood poses a threat to their unborn babies.

The Australian Red Cross Blood Service honored Harrison's profound impact, noting that he began his journey as a donor after receiving transfusions for major chest surgery at the age of 14. His altruistic commitment to donating blood plasma began when he turned 18, continuing dutifully every two weeks until he was 81 years old. In 2005, he set a world record for the most blood plasma donated, a title that remained with him until 2022 when a donor in the U.S. surpassed his achievement.

Harrison’s daughter, Tracey Mellowship, reflected on her father's pride in saving so many lives effortlessly, emphasizing that he believed the donation process was painless, and the lives saved could be one's own. Mellowship, along with two of Harrison’s grandchildren, are among the recipients of Anti-D immunizations, reinforcing the legacy of his life-saving contributions.

Before the introduction of the Anti-D intervention in the mid-1960s, half of the babies diagnosed with Hemolytic Disease of the Fetus and Newborn (HDFN) did not survive. The condition arises when a mother's red blood cells clash with her baby's, leading to severe health risks for the unborn child. The exact reason behind Harrison's rich Anti-D blood remains uncertain, although it is speculated that the extensive transfusions he underwent in his teens played a significant role.

Currently, there are less than 200 active Anti-D donors in Australia, collectively aiding around 45,000 mothers and their children annually, as highlighted by the Australian Red Cross Blood Service. Lifeblood has initiated collaboration with the Walter and Eliza Hall Institute of Medical Research to cultivate Anti-D antibodies in laboratories, aiming to eventually expand treatment availability for pregnant women globally. "Creating a new therapy has long been a 'holy grail,'" stated Lifeblood's research director, David Irving, indicating the critical need for dedicated donors who can consistently produce high-quality antibodies.
