Parental concerns about the safety of childhood vaccinations began in the 1990’s and continue until today. A primary concern of many parents is whether the adjuvants and preservatives added to the vaccines have the potential to cause neurodevelopmental disorders in young children. An overview of various studies was done to determine if thimerosal affects childhood neurodevelopment with studies suggesting that thimerosal potentially causes neurodevelopmental disorders. However, some studies suggest the opposite. As a result it is impossible to conclude whether thimerosal affects childhood neurodevelopment. However, measures should be taken to remove thimerosal from the childhood vaccination schedule. Additionally, the studies must be done to determine if other components of vaccines can have adverse effects on the developing nervous system.
