James Harrison is credited with saving the lives of 2.4 million babies. His plasma contained a rare antibody called anti-D, which is used in medications to prevent haemolytic disease of the fetus & newborn #HDFN, aka #RhesusDisease, a potentially dangerous disease for unborn babies. His plasma is now being studied to create a synthetic version to prevent future deaths of unborn babies.
