In case you missed it, the medical journal The Lancet has retracted it’s oft-cited study that purported to find a link between the Mumps/Measles/Rubella vaccine and autism:

[T]he study by British surgeon and medical researcher Andrew Wakefield and his colleagues appeared in 1998 in The Lancet, “the arguments were considered by many to be proven and the ghastly social drama of the demon vaccine took on a life of its own.”
…Ten of Wakefield’s 13 co-authors renounced the study’s conclusions several years ago and The Lancet has previously said it should never have published the research.
“It has become clear that several elements of the 1998 paper by Wakefield … are incorrect,” the internationally renowned scientific journal said in a statement Tuesday. “We fully retract this paper from the published record.”

It has also, perhaps, started some media navel-gazing (h/t) regarding how they report preliminary scientific findings or theories as new “facts”….or, dare we say, consensus?
