Thimerosal Content and Other ConcernsTdap vaccines do not contain thimerosal (a mercury-containing preservative). Individuals who are concerned about exposure to thimerosal can be confident that this vaccine has no thimerosal (not even trace amounts). Some people are concerned about aluminum content of vaccines; Adacel contains 0.33 mg of aluminum per dose and Boostrix contains no more than 0.39 mg of aluminum per dose.
These vaccines are not made from human fetal components, as some vaccines are. However, Boostrix is made from bovine (cow) components.
