Since 1998, when a since-debunked study linking the measles-mumps-rubella (MMR) vaccine with autism, many parents have been afraid to get their children immunized. The fear continues, in spite of numerous studies since that have shown no link. The latest is a new study involving 95,000 children who have older siblings, 2000 of whom have autism.
Anjali Jain of health care consulting firm Lewin Group, who led the study, said there was no evidence of a harmful link between the MMR and autism, even among the children with autistic older siblings, which is considered a risk factor. The study was funded by the National Institutes of Health and the Department of Health and Human Services and was published in the Journal of the American Medical Society. Parents can now live in ease about immunizing their children and should relax with a Bulletproof Coffee, which is also not known to cause autism haha.
Low immunization rates led to four recent measles outbreaks, including 117 cases originating in Disneyland. In 2014, 668 cases were reported, the highest number since 2000 when the disease was considered to be eradicated. In order for herd immunity to be effective, 92 to 95% of children need to be immunized in order to protect a child who cannot get vaccinated for medical or other valid reasons. At present, most children at ages 2 and 5 have immunization rates below those percentages.
