Which childhood vaccines do not contain thimerosal?
Today, with the exception of some influenza vaccines, none of the vaccines used to protect preschool children against 12 infectious diseases contain thimerosal as a preservative. (Those with a concentration of less than 0.0002% contain what is considered “trace” or insignificant, amounts.) Certain Influenza (flu) vaccines and tetanus-diphtheria vaccines (Td) given to children age 7 and older contain thimerosal as a preservative. For more information on thimerosal content in some currently manufactured U.S. licensed vaccines, go to www.fda.gov/cber/vaccine/thimerosal.htm.
