Blasted almost as soon as it was published, a 1998 study linking the measles, mumps and rubella (MMR) vaccine to autism has still managed to scare off hordes of anxious parents from fully vaccinating their children. Now a new investigative report published in the British Medical Journal (BMJ) goes further, saying that the study was not only rife with error, but outright fraud, committed for financial gain.
The new report shows how the study's author altered facts about his patient's medical histories so they would fit more neatly with his claims.
