It was inevitable that the media would re-ignite the MMR (measles, mumps, rubella) autism scare during Andrew Wakefield's General Medical Council hearing (doi: 10.1136/bmj.39280.513310.4E). In the past two weeks, however, one front page splash in the broadsheet Sunday newspaper the Observer (8 July) has drawn widespread attention: the newspaper effectively claimed to know the views of named academics better than those academics themselves, and to know the results of research better than the people who did it. Smelling a rat—as one might—for once, I decided to pursue every detail.

The Observer's story made three key points: that new research had found an increase in the prevalence of autism, to 1 in 58; that the lead academic on this study was so concerned he suggested raising the finding with public heath officials; and that two “leading researchers” on the team believed that the rise was due to the MMR vaccine. By the time the week was out, this story had been recycled in several other national newspapers, and the 1 in 58 figure had even been faithfully reproduced in a BMJ news article (doi: 10.1136/bmj.39272.468044.4E).

I contacted the centre: the study that the Observer reported is not finished and is not published. The data have been collected, but they have not been analysed.

Unpublished data is a recurring theme in MMR scares, and it is the antithesis of what science is about: …
