Andrew Wakefield, the gastroenterologist infamous for making a now-discredited link between vaccines and autism, is suing the British Medical Journal for libel, reports ScienceInsider's Sara Reardon. In 1998, Wakefield published an article in the Lancet (it has since been retracted) linking the MMR vaccine to autism and bowel disease. That article was immediately challenged and discredited, Reardon says.
