A recent study has discovered that thimerosal, a mercury-containing chemical compound that is used in vaccines and immune globulin formulations, does not have an effect on neuropsychological functioning in kids aged between 7 to 10.

Thimerosal, developed and registered under the brand name ‘Merthiolate’ in 1929 by the pharmaceutical company Eli Lilly, is an organomercury compound having around 49.6% mercury by weight. Besides being used as a preservative in vaccines since the 1930s, it is also used as an antibacterial as well as antimycotic agent.

Rising argumentations over vaccine safety and dangers linked with mercury exposure from thimerosal-containing vaccines, but, forced the American health agencies to take action for deletion of thimerosal from all baby vaccines. The compound was completely eliminated from childhood vaccines by 2002.

For the analysis, the scientists took 1047 children aged between 7 and 10 years, and administered standardized examinations evaluating 42 neuropsychological consequences, comprising I.Q. tests, language and language indexes, verbal remembrance, motor coordination among others.
The children’s exposure to mercury from thimerosal was ascertained from computerized immunization reports, medical histories, personal vaccination records, and parent consultations.

Afterwards the scientists assessed the relationship between existing neuropsychological recital and exposure to mercury in the prenatal stage, the neonatal period (birth to 28 days), and the first 7 months of life.

To conclude, the rising level of mercury exposure was linked with better performance in 12 neuropsychological testings, whereas, seven displayed unconstructive response.

Therefore, in no case the study completely supported a connection between early revelation to mercury from thimerosal-containing vaccines and deficits in neuropsychological processing at the age of 7 to 10 years.

The study researchers’ concluded that thimerosal in vaccines is quite beneficial.

While, engaging thimerosal for causing a pandemic of childhood autism still continues, the study does not review thimerosal’s link with autism starightly.

In the meantime, about 5,000 couples are looking for legal compensation in aid of children who developed autism after getting vaccinations.

Repeating his point again, Dr. Anne Schuchat, a representative with the Centers for Disease Control and Prevention, stressed that there was no methodical support for the theory that thimerosal caused autism. In spite of thimerosal’s elimination from vaccines, there has been no proof of decline of autism.
