Thimerosal Content and Other Concerns
Comvax does not contain thimerosal (a mercury-containing preservative). Parents who are concerned about exposing their children to thimerosal can be confident that this vaccine has no thimerosal -- not even trace amounts.
Some parents also are concerned about the aluminum content of vaccines. Comvax contains 225 mcg (0.225 mg) of aluminum per dose.
This vaccine is not made from human fetal components or animal components, unlike some vaccines.
Comvax is made by Merck & Co., Inc.
