If the Lancet case report did not say MMR causes autism, and if his collection of biopsies for research purposes was pre-approved by the Ethical Practices Committee, why is there a case against Dr. Wakefield (and colleagues)?
Medical authorities in the UK (and the United States) do not like it when licensed medical professionals ask questions about vaccine safety. Licensed medical professionals and medical researchers who question vaccine safety are more difficult to dismiss than parents who notice adverse reactions after vaccination. The prosecution of Dr. Wakefield, Professor Walker-Smith and Professor Murch is an example and warning to other licensed medical professionals and researchers. The warning is clear: If you question the safety of a vaccine, you put your license and career at risk.
