Rett syndrome is when gene “…MeCP2, a protein that dims the activity of many genes in nerve cells that influence synapse formation or function. The Absence of MeCP2 causes dendrites, tree-like structures on neurons that receive incoming messages, to contain fewer spines, or spots for synapses to grow. The synapses that do develop do not function normally” (Bilimoria). Affecting mostly females this syndrome causes the connections to be extremely weak. Rett syndrome causes slow growth, loss of normal movement and coordination, loss of communication abilities, abnormal hand movements, unusual eye movements, breathing problems, agitation and irritability, cognitive disabilities, seizures, scoliosis, irregular heartbeat, and pain (“Rett syndrome”).

This virus while not harmful unless the infected individual has a weak immune system, can cause autism in the developing brains of newborns. When giving birth the mother can pass on “Congenital CMV [which] is a known cause of autism” (“About CMV”). Congenital CMV occurs when an infant is infected before birth. The infection spreads through the placenta, the developing child’s brain is then affected by the virus which could lead to …show more content…
Research shows that thimerosal does not cause ASD. In fact, a 2004 scientific review by the IOM concluded that "the evidence favors rejection of a causal relationship between thimerosal–containing vaccines and autism." Since 2003, there have been nine CDC-funded or conducted studies[PDF - 357 KB] that have found no link between thimerosal-containing vaccines and ASD, as well as no link between the measles, mumps, and rubella (MMR) vaccine and ASD in children. (“Vaccines Do Not Cause Autism”)
Vaccines have been tested many different times in order to prove that there is no link between them and autism. The CDC has specifically looked at the thimerosal containing vaccines because that was the part of the vaccine people previously believed caused autism. With all of the research that they have done with the thimerosal containing vaccines they have found that vaccines are safe and essential.
