| Original Source Material: Barbara Loe Fisher, the parent of an autistic child and co-founder and president of the National Vaccine Information Center, believes that some cases of what she terms the "regressive" form of autism may be linked to the [measles-mumps-rubella] MMR vaccine. She says regressive autism is characterized by a sudden developmental downturn in a child who had previously been developing normally. The National Vaccine Information Center is a nonprofit educational organization in Vienna, Virginia, established by parents whose children were injured or died following vaccination. | Source:

Original Source Material: This eighth and final report of the Immunization Safety Review Committee examines the hypothesis that vaccines, specifically the measles-mumps-rubella (MMR) vaccine and thimerosal-containing vaccines, are causally associated with autism. The committee reviewed the extant published and unpublished epidemiological studies regarding causality and studies of potential biologic mechanisms by which these immunizations might cause autism. The committee concludes that the body of epidemiological evidence favors rejection of a causal relationship between the MMR vaccine and autism. The committee also concludes that the body of epidemiological evidence favors rejection of a causal relationship between thimerosal-containing vaccines and autism. The committee further finds that potential biological mechanisms for vaccine-induced autism that have been generated to date are theoretical only. |

Original Source Material: We analyzed data from a case-control study conducted in 3 managed care organizations (MCOs) of 256 children with autism spectrum disorder (ASD) and 752 control children matched on birth year, sex, and MCO. In addition to the broader category of ASD, we also evaluated autistic disorder and ASD with regression... The aOR (95% CI) of ASD associated with each 25-unit increase in total antigen exposure was 0.999 (0.994–1.003) for cumulative exposure to age 3 months, 0.999 (0.997–1.001) for cumulative exposure to age 7 months, and 0.999 (0.998–1.001) for cumulative exposure to age 2 years. Similarly, no increased risk was found for autistic disorder or ASD with regression. In this study of MCO members, increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines during the first 2 years of life was not related to the risk of developing an ASD. |
