James Heilman makes a very important point [http://www.hifa.org/dgroups-rss/lancet-medical-misinformation-and-intern... which every journal editor, editorial board, publisher, and every researcher and author needs to learn from.
In addition, his point alerts everyone to the infallibility of human beings, and reminds us all of the well-known challenges of the peer review system of screening submitted manuscripts before they are published, to become part and parcel of the literature.
I suppose one way to control the damage that misinformation leads to, is that once it is discovered the same alacrity and level of resources must be applied without any delay to retracting and publicising the retraction to the world. In the case of the MMR falsehood, the retraction must be publicised to the lay media and general public in many languages as well, from the beginning. That is without prejudice to all the extant regulatory and professional sanctions that take place to deter other such publications of misinformation.
