Doesn't the flu vaccine still contain thimerosol?

Thimerosol is found in some forms of the flu vaccine but not in all of them -- here's why: "The least expensive form of flu vaccine is the ten-dose vials for which a new needle and syringe are used for each patient but ten patients would get vaccine from the same vial and those vials do contain thimerosol," says Lance Rodewald, M.D., director of the immunization services division at the Centers for Disease Control and Prevention. "However, the single-dose injectable forms of influenza vaccine do not contain thimerosol, nor does the mist that goes in the nose, so parents can find thimerosol-free influenza vaccines very easily."  But again, the ethylmercury in thimerosal does not build up in the body and has never been linked to adverse effects.
