This was a 12 year old study linking certain vaccines to autism. The author has been accused of improper research methods. It is old news, in any event. Here is a link to The Lancet squib -- and a snippet:
. . . .Following the judgment of the UK General Medical Council's Fitness to Practise Panel on Jan 28, 2010, it has become clear that several elements of the 1998 paper by Wakefield et al., are incorrect, contrary to the findings of an earlier investigation. In particular, the claims in the original paper that children were "consecutively referred" and that investigations were "approved" by the local ethics committee have been proven to be false. Therefore we fully retract this paper. . . .
"The allegations against me and against my colleagues are both unfounded and unfair. We invite anyone to review the record, and to draw their own conclusions," Wakefield said in a statement.
