The Lancet has retracted the article that provided the fuel for one of the most pernicious and dangerous memes of the last ten years: that routine childhood vaccinations cause autism. The authors of the article were found to have falsified the evidence.
Unfortunately the damage this has caused is very hard to undo. Countless children were not immunized because of this article and the panic it generated. Thousands of parents will still believe it, and the retraction will form part of the “cover-up” that conspiracy theorists love.
Meanwhile, measles, rubella, and mumps, in case you needed reminding, are not trivial illnesses.
