TY - JOUR T1 - CHange in medium for scarlet fever toxin AU - Dick GH Y1 - 1939/09/16 N1 - 10.1001/jama.1939.02800370066027 JO - Journal of the American Medical Association SP - 1150 EP - 1150 VL - 113 IS - 12 N2 - To the Editor:—  Some persons who have received injections of diphtheria toxoid, especially the alum precipitated toxoid, may be sensitized to proteins contained in veal broth and consequently develop urticaria following injection of other veal broth preparations.To avoid the development of urticaria in such persons during the course of immunization against scarlet fever, the medium in which scarlet fever toxin is produced has been changed to one which contains no meat infusion. Use of this medium results in a toxin containing considerably less protein and a marked reduction in the incidence of urticaria.
