There was Andrew Wakefield.
But there have been so many others. Especially the Netherlands seems to have lots of scandals. Today, in the Volkskrant (one of the main Dutch papers) it is claimed that a very eminent cardiologist (Don Poldermans) on whose research EU guidelines re cardiology were based has committed fraud on a much wider scale than previously thought and wrong European guidelines (based on this fake research as he made up his own data amongst other things) may have cost 800,000 patients their life.
Integrity seems to be such a huge problem in society, bankers, doctors, scientists, politicians, etc. etc. etc. Obviously not all, but too many seem to think they can act with impunity. Did any one of them go to jail?
