The study, published Thursday in the journal npj Vaccines by researchers at Massachusetts General Hospital, looked at nine people with type 1 diabetes who were given a vaccine to prevent tuberculosis, called bacillus Calmette-Guérin (BCG). They had two injections, four weeks apart.

Levels of their hemoglobin a1c (HbA1c), which measures a person’s blood sugar, dropped more than 10% three years after treatment and by more than 18% four years after treatment. The researchers also found that the blood sugar levels of people in the trial were able to remain at near-normal levels for up to eight years. On average, the people in the trial had lived with type 1 diabetes for 19 years.
