Thimerosal Content and Other Concerns

Menactra does not contain thimerosal, a mercury-containing preservative. People who are concerned about exposure to this substance can be confident that this vaccine has no thimerosal -- not even trace amounts. Some people also are concerned about the aluminum content of vaccines. This vaccine contains no aluminum.
Menactra is not made from animal components or human fetal cell lines, unlike some vaccines.
