Thimerosal Content and Other ConcernsParents who are concerned about exposing their children to thimerosal can be confident that the available rotavirus vaccines contain no thimerosal (a mercury-containing preservative), not even in trace amounts. Some parents are concerned about aluminum content of vaccines; these vaccines contain no aluminum.
