Vaccines for mumps, rubella, and measles and particularly those vaccines that contain the ethyl mercury containing preservative thimerosal have been accused of causing autism and autism spectrum disorders in children that received the vaccinations. A new study conducted by Bharathi S. Gadad with the Department of Psychiatry at the University of Texas Southwestern Medical Center in Dallas, Texas and colleagues has shown no relationship between brain changes and social reactions associated with autism and any vaccinations. The study was reported in the Sept. 28, 2015, edition of the journal Proceedings of the National Academy of Sciences.
The study used infant rhesus macaques and examined the neuropathological changes associated with autism spectrum disorders in the cerebellum, amygdala, and hippocampus of the monkeys for 18 months. The schedule of vaccination was selected to mimic recommended pediatric vaccine schedules from either 1990 or 2008. A complete social development profile was developed for each test animal. The relative development of autism in the test animals was measured against a group of macaques that received no vaccinations. No evidence that the vaccinations produced autism was found.
The validity of the research might be questions on the basis of funding but one of the major funding groups for the study was the National Autism Association. Macaques are as similar to humans in brain development in infancy as possible. The research began and concluded prior to the most recent anti-vaccine protests led by know nothing experts like Jim Carrey and concluded before the most recent statements about vaccines tied to the upcoming Presidential election.
Several lawsuits have been filed that claim vaccines caused autism. The study dashes the hopes of lawyers for a huge settlement from vaccine manufacturers. The most recent research indicates that autism is in majority a result of genetic factors and one of the most prominent causes of autism that can be verified is the age of the father at conception.
The study shows vaccines do not cause autism and indicates there is a question as to responsibility for having a child with autism. Genetic profiling can establish the probability of having a child with autism so why tax the public to pay for a personal choice on the part of parents. Equally incongruous is the taxing of the public to pay for diseases that children develop due to their parent’s unreasonable fears of vaccinations.
