And Horton of The Lancet again in April '15Sure! They actually retract publications when they find evidence of fraud or malfeasance.
Have yet to see your anti-vaxxers acknowledge the MMR/autism claims are bogus. Yet both that "study" was retracted AND multiple other studies never identified any correlation (in fact, the Danish study, as I recall, actually identified a trend toward PROTECTIVE aspects of those vaccines relative to autism rates).
“The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue. Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness.”
