The first formal immunisation schedule for the delivery of triple (DTP) vaccine was drawn up in November 1960. Since 1960 there have been many changes to the immunisation schedule, with a further change proposed for 1996. These changes have been in response to new vaccine development and better understanding of vaccine immunology. Further changes are certain.
