In 1998, Andrew Wakefield published a study in The Lancet claiming a link between the MMR (measles, mumps, rubella) vaccine and autism. His study included 12 children whose parents reported autism symptoms appearing after MMR vaccination. He proposed a new condition called “autistic enterocolitis.” In 2002, a Danish study analyzed health records of 537,303 children and found autism rates of 0.92% in vaccinated children versus 0.98% in unvaccinated children (not statistically different). In 2004, investigative journalists discovered Wakefield had received £435,000 from lawyers suing vaccine manufacturers and had not disclosed this conflict of interest. Ten of his 12 co-authors retracted their support for the paper’s conclusions. In 2011, the British Medical Journal published an investigation showing Wakefield had altered patient records and timelines in his original study. Multiple subsequent studies in Japan, the United States, and other countries involving over 1.2 million children found no association between MMR and autism.
