Current thinking on the part of many investigators is that for some children, vaccines, or something in the vaccines, may be a cause of learning disabilities, including autism. Mercury levels normalize and are metabolized in the system to normal levels. Either Children receive a cocktail of vaccinations beginning at birth. However, these vaccines also contain the preservative thimerosal, which is designed to minimize bacterial growth in the vaccine.
Medication given to an infant has a dosing requirement and safety level.
In fact, the FDA has turned back to the drug companies and asked that they make all childhood vaccines without mercury. Before vaccinating your child, ask your doctor if the vaccine is thimerosal free. Although the drug companies have begun to create vaccines without thimerosal, some manufacturers are still making and selling the old vaccines, and many doctors are still giving them to children. Don't allow your child to have an unnecessary booster, be vaccinated when sick or be vaccinated for more than one disease at a time. Talk to your pediatrician about the options that are available to you and any concerns you may have regarding thimerosal.
