An Open Letter
To Whom It May Concern

We are writing to you as parents of the children who, because of their symptoms of inflammatory bowel disease and associated autism, were seen at the Royal Free Hospital Paediatric Gastroenterology Unit by Professor Walker-Smith and Dr. Simon Murch with the involvement of Dr Andrew Wakefield on the research side of their investigations. Our children became the subjects of a paper published in The Lancet in 1998.
