Immunizations - Measles, Mumps, and Rubella

Most publicity has centered on a possible link between the MMR vaccine, which was introduced in 1988, and a variant of autism that includes inflammatory bowel disease (IBD) and impaired behavioral development. Such findings have been rigorously reviewed and refuted in a number of well-conducted studies. Of special note, a 2002 analysis of vaccination records of children born between 1979 and 1998 found no higher incidence in autism, with or without behavioral problems and gastrointestinal disorders. In the study, there was a link between impaired behavioral development and bowel problems, but they were not related to the vaccine.

Despite considerable publicity, there is no evidence linking MMR vaccination with the development of autism. The Centers for Disease Control & Prevention (CDC) website provides extensive information on this matter. The popular media has incorrectly reported the possible link between autism and MMR as causing a split in the scientific community, but virtually all experts refute any association. In fact, reports of symptoms related to autism increased only after widespread publicity of this supposed side effect.

The potential benefits from receiving the MMR vaccine far outweigh the potential adverse effects. Measles, mumps, and rubella are all very serious illnesses and each may have complications resulting in lifetime disabilities or even death. The incidence of such complications, related to having the actual diseases, is far greater than the potential of developing serious, or even moderate, adverse effects due to the MMR vaccine.
