The author of a discredited report linking autism to the measles-mumps-rubella (MMR) vaccine has filed a defamation suit against the British Medical Journal. Andrew Wakefield launched his libel case against three defendants in the United States last week. The gastroenterologist is suing investigative journalist Brian Deer for a BMJ article which analysed his data and accused him of fraud; BMJ editor Fiona Godlee who supported the accusation in an editorial, and the BMJ as a whole. Wakefield claims that the journal acted with malice and suggests a conflict of interest because the BMJ receives money from vaccine makers GlaxoSmithKline and Merck.
