Australian James Harrison's rare blood saves more than 2 million babies

The video explains how rhesus incompatibility between a pregnant woman and her baby can lead to the mother's body producing antibodies that attack the baby's red blood cells, a process known as sensitization.

This injection prevents rhesus negative women from developing antibodies against the baby's red blood cells during pregnancy.
