Vaccines and Autism

The measles, mumps, and rubella (MMR) vaccine is used to immunize children against diseases that can cause major disabilities and fatal illnesses. In 1994, the vaccine was mandated for all school children and since then a spike has been seen in the diagnosis of autism. Many of those diagnosis falls within a few months of the MMR vaccine and in 1998, Andrew Wakefield published a study indicating a relationship between the MMR vaccine and autism (Rudy, 2009). Intense media coverage followed and many parents refused to give their children the MMR vaccine, believing their children would develop autism. The study was later retracted due to the lack of evidence but many children are still not receiving the MMR vaccine. The public health field has tried to raise awareness about the benefits of the MMR vaccine but many are still skeptical about the vaccine. Efforts have now been focused towards increasing awareness about the vaccine and trying to encourage parents to get their children vaccinated. In February 1998, The Lancet published an article entitled “Ileal-Lymphoid-Nodular Hyperplasia, Non-Specific Colitis, and Pervasive Developmental Disorder in Children,” which suggested that the measles, mumps and rubella (MMR) vaccine could contribute to the development of autism. Dr. Andrew Wakefield, a gastroenterologist, suggested the link between the MMR vaccine and autism. Wakefield proposed that the virus could “have a negative impact on a child’s immune system, lead to persistent infection in the gastrointestinal tract and lead, in the long run, to possible brain damage and autism” (Rudy, 2009). Eight of the twelve children had severe intestinal inflammation, with symptoms emerging six days after receiving the MMR vaccine. The vaccine had damaging effects on the intestines and caused serious inflammation, “allowing harmful proteins to leak from the gut into the bloodstream and from there to the brain, where they damaged neurons in a way that triggered autism” (Begley,
