  "When vaccinations were considered as possible risk factors for diabetes, a significant decrease in relative risk estimated as odds ratio (OR) was noted for measles vaccination (OR = 0.69; 95% confidence limits 0.48-0.98). For vaccination against tuberculosis, smallpox, tetanus,
whooping cough, rubella and mumps no significant effect on OR for
diabetes was found. . . .

In conclusion, a protective effect of measles vaccination for Type 1 diabetes in childhood is indicated as well as a possible causal relationship between the onset of the disease and the total load of recent
infections. "
