Immunizations and Type 1 Diabetes
In the past several years, there have been several press reports about claims that vaccinations of young children cause type 1 diabetes. Specifically mentioned is the Haemophilus influenzae type b (Hib) vaccine. Given the proven health benefits of vaccinations and the desire to prevent Type 1 diabetes, these concerns are clearly worth investigating. However, there are many peer reviewed studies, published in respected scientific journals, that show no correlation between immunizations and increased risk for Type 1 diabetes. The claims of an association between immunizations and type 1 diabetes are not supported by the data, according to the studies referenced below.
Information About Vaccines and Diabetes
- Childhood Vaccination and Type 1 Diabetes, published in the April 1, 2004 issue of The New England Journal of Medicine, concludes that the study " ... results do not support a causal relation between childhood vaccination and type 1 diabetes." The full text of this study is freely available in HTML and PDF formats.
- Childhood vaccinations, vaccination timing, and risk of type 1 diabetes mellitus, published in the December 2001 issue of Pediatrics, concluded "... we did not find an increased risk of type 1 diabetes associated with any of the routinely recommended childhood vaccines." (DeStefano F, Pediatrics 2001;108:E112) The full text of this study is freely available in HTML format and PDF format. This study set out to explore the hypothesis that vaccinations and the timing of vaccinations caused type 1 diabetes and found no association.
- Lack of association between early childhood immunizations and beta-cell autoimmunity, a peer-reviewed study which found no association between childhood vaccinations -- including Hib -- and increased risk of Type 1 diabetes. (Diabetes Care 1999 Oct;22(10):1694-7) The full text of this study is available in PDF format.
- Diabetes and Vaccines from the Centers for Disease Control and Prevention contains extensive citations of studies that show no association between vaccinations, vaccination timing, and the development of type 1 diabetes.
- What do you make of the latest reports about the association between type 1 diabetes and Hib vaccine? from "Ask the Diabetes Team" (November 1999).
- Association between type 1 diabetes and Haemophilus
influenzae type b vaccination: birth cohort study, a peer-reviewed study which concludes that there is no association between Hib vaccination and increased risk of Type 1 diabetes. (BMJ 1999;318:1169-1172) The full text of this study is available in PDF format.
