The presentation made by Dr. Verbickij is important in several respects. First, it is an excellent piece of work on the immunology of pregnancy. Next, it shows how a model can be established in a non-human primate to facilitate research on clinical problems.

The stimulus to much of the early research was the development of methods to prevent rhesus haemolytic disease in human neonates. We are all familiar with the great progress being made in these studies following the introduction of the use of anti-Rh serum (Clarke 1968).
