Xanthan gum is a common additive that’s used to thicken and stabilize many types of food such as salad dressings, soups, syrups and sauces. Since then, thimerosal has been the subject of numerous studies (see Bibliography- Notable Studies and Assessments Supporting the Safe Use of Thimerosal in Vaccines) and has a long record of safe and effective use preventing bacterial and fungal contamination of vaccines, with no ill effects established other than minor local reactions at the site of injection. Pediatrics 118;e139-e150. (see Bibliography- Notable Studies and Assessments Supporting the Safe Use of Thimerosal in Vaccines).

Fombonne, E., et al., (2006) Pervasive Developmental Disorders in Montreal, Quebec, Canada: Prevalence and Links With Immunizations. The documented antimicrobial properties of thimerosal contribute to the safe use of vaccines in multi-dose vials, and the ability to package certain vaccines, such as those for seasonal and pandemic influenza, in multi-dose vials helps facilitate immunization campaigns in the United States and globally that save lives. Am J Dis Child 1981;135:826-828. Pichichero ME, Gentile A, Giglio N, Alonso MM, Fernandez Mentaberri MV, Zareba G, Clarkson T, Gotelli C, Gotelli M, Yan L, Treanor J.
