Addition of the Hepatitis B Vaccine in 1988 Increased the Rate of Type 1 Diabetes 1.62X in Children in New Zealand. The incidence of type I diabetes in person 0-19 years old living in Christchurch rose from 11.2 cases per 100,000 children annually in the years before the immunization program, 1982-1987, to 18.1 cases per 100,000 children annually ( P = .0008) in the years following the immunization, 1989-1991.


The timing of pediatric immunizations and the risk of Insulin-Dependent diabetes mellitus


Classen David C.; Classen, John Barthelow; Infectious Diseases in Clinical Practice: September-October 1997 – Volume 6 – Issue 7 – ppg 449-454.


Insulin-dependent diabetes mellitus (IDDM) is believed to be an autoimmune disease induced by a variety of environmental stimuli. Vaccines and infectious agents have been suggested to have an influence, but most of this research has been centered on the ability of these agents to infect the pancreatic islet cells or contain antigens that mimic autoantigens. Classen found that administration of the diphtheria-tetanus-pertussis (DTP) and anthrax vaccines to mice and rats at birth prevented the development of diabetes, whereas administration of the DTP vaccine starting at 8 weeks was associated with an increased incidence of diabetes.
