Mumps, measles and rubella vaccine and the incidence of autism recorded by general practitioners: A time trend analysis. British Medical Journal Risk of autism increased fourfold in the UK between and Do children who become autistic consult more often after MMR vaccination? No difference in consulting behaviour was seen in the six months post MMR. Any dramatic effect of MMR on behaviour seems unlikely. JAMAMar 79 p Percentage of children immunized with MMR between and was compared with incidence of autism during same period.
Vaccines & Autism
Although a dramatic increase in autism incidence was found, the percentage of children that received MMR was unchanged. No causal association exists between MMR vaccination and the risk of autism. Davis R L, et al. Measles-mumps-rubella and other measles-containing vaccines do not increase the risk for inflammatory bowel disease.
Archives of Pediatrics and Adolescent Medicine Report of measles-mumps-rubella vaccine and autism. The American Academy of Pediatrics hosted a multidisciplinary international workshop to review the evidence regarding a possible association between MMR vaccine, inflammatory bowel disease and autism spectrum disorders, specifically autism with regression.
It decided a considerable body of evidence did not support a causal relationship between MMR vaccine and autism or inflammatory bowel disease. In addition, it found no data to suggest the separate administration of measles, mumps and rubella vaccines would offer any potential benefit over the MMR vaccine.
In fact, it voiced its concern that such an approach would result in many under-immunised children. Further evidence against a causal association. Re-examined previous research, published in The Lancet, which examined signs of autism in children shortly after they received the combined vaccine. Following criticism that the onset of autism may not necessarily be short, the new research looked at the data from the same autistic children who had taken part in the first study but used an extended timescale.
The results provided further evidence against a causal association between the MMR vaccine and autism. Worries are not justified. Archives of Disease in Childhood ; It concluded that there is neither experience nor research evidence for giving the triple vaccine separately anywhere in the world.
There is no case for introducing single vaccines and worries over MMR are unjustified. Pediatrics ; Oct ;4 e Compares autistic children who have had MMR to those who have not. It failed to support an association between MMR and regressive autism and concluded that, when combined, current findings did not argue for changes in current immunisation programmes and recommendations.

MMR and autism: further evidence against a causal association.
It stated that the first symptoms of autism appear over a year after the MMR vaccine and claimed prior research is invalid. However, it provided no evidence to link MMR to autism and the authors failed to produce any scientific references. Time trends in autism and in MMR immunization coverage in California.

Taylor B, et al. Measles, mumps and rubella vaccination and bowel problems or developmental regression in children with autism: A PDF of this report is available at: Relation of childhood gastrointestinal disorders to autism: British Medical Journal ; This study, using the General Practice Research Database, looked at whether children with autism are more likely to have a history of gastrointestinal disorders than children without autism.
All children born between 1 January and 31 December were reviewed. A population-based study of measles, mumps and rubella vaccination and autism. New England Journal of Medicine ; A retrospective cohort study published in the New England Journal of Medicine reviewed overchildren born in Denmark.
The main objective of this study was to evaluate whether there was an association between MMR vaccine and autism. Neurologic disorders after measles-mumps-rubella vaccination.
A further study was published in the journal Pediatrics. The aim of this study was to assess whether there was an association between MMR vaccination and encephalitis, aseptic meningitis, and autism. This retrospective record linkage study in Finland looked at overchildren aged between 1 and 7 years of age vaccinated during November and June This study did not identify any association between MMR vaccination and encephalitis, aseptic meningitis or autism.
Inflammation and inflammatory bowel disease. Effect of Pentavac and measles-mumps-rubella MMR vaccination on the intestine. Infants were reviewed before, and 2 and 4 weeks after immunisation with Pentavac for the presence of intestinal inflammation. This paper did not find any evidence of intestinal inflammation during the 4 weeks following MMR or Pentavac immunisation. However, his referenced study was found to be fraudulent, and no evidence of persistent infection has been shown in studies that used appropriate methods .
Another proposed trigger for ASD was thimerosal, an ethyl-mercury containing preservative that used to be present in some vaccines, although not in the MMR vaccine. This theory was based on observed similarities in some features of ASD and mercury poisoning ; however, the degree of these similarities and the plausibility of this suspected association was refuted by neurologists .
