The age of the MMR vaccine is 12 to 15 months. When a child develops autism, their parents express the disease as normal growth until they reach the age at which their degenerative process begins. This problem usually occurs around 2 years old. Parents say that children grow normally, but many researchers do not believe that children actually grow from 1 to 2 years of age, but some children usually occur after MMR vaccination It goes through a regression process.

There is no scientific evidence that MMR vaccines can cause autism. The issue of the possibility of association between MMR vaccine and autism is being extensively studied by a group of independent experts in the United States including the National Academy of Medical Research Institute (now renamed as the National Medical School). These reviews conclude that existing epidemiological evidence does not support the causal relationship between MMR vaccine and autism. MMR vaccines may lead to the recommendation for autism arising from gastroenterology studies in the Wakefield of Andrews, England. In 1998, Wakefield and colleagues published an article by Lancet that MMR's measles vaccine virus caused inflammatory bowel disease and claimed that harmful proteins enter the bloodstream and damage the brain.

Does MMR vaccine cause autism? The answer to this question is no. - Immunization has been taking place for two centuries and has effectively eliminated more than a dozen of the most common infections in the past. H. Influenza, hepatitis A and hepatitis B, measles, mumps, colds, whooping cough, tetanus and rubella have completely eradicated diphtheria, polio and smallpox (Culp-Ressler). Ethics, ethics, safety and effectiveness of vaccination, in particular there is a big difference between children.

In the literature review, there are few studies supporting the association between vaccine and autism, and most studies showed causality between measles, mumps, rubella (MMR) vaccine and autism Is not ... In addition, the vaccine preservative thiomersal is hypothesized to have a causal effect in autism. Peripheral blood mononuclear cells were isolated from 54 children with ASD and 34 normal children with development and were subjected to up to 4 real time polymerase chain reaction assays and 2 nested polymerase chain reaction assays. Samples from the ASD or control group were not found to contain nucleic acids from any measles virus gene. In nested polymerase chain reaction and internal assay, none of the samples gave a positive result. Furthermore, there was no difference in anti-measles antibody titer between autism and control.
