Common childhood vaccinations, including newer ones such as those for hepatitis B, do not cause children to develop diabetes. The conclusion came from a look at 768 diabetes-free children who were compared to 252 others who had juvenile diabetes. Those who had been vaccinated against hepatitis B, whooping cough, chickenpox and other diseases were no more likely to have developed diabetes than those who had not been given the vaccines.
Researchers at the U.S. Centers for Disease Control and Prevention and a number of health care institutions in Oregon, Washington who conducted the study said earlier research also had not shown an association but a fresh look had not been taken since 1990 when some newer vaccines came into use. The cause of juvenile diabetes is not known but genetic and environmental factors are believed to be involved.
