Summary

This trial will test if a second BCG vaccination can help kids with Type 1 diabetes by improving their immune and metabolic systems.

Who is the study for?

This trial is for kids aged 12-17 with Type 1 diabetes, who can manage multiple daily insulin injections and use a continuous glucose monitor (CGM). They must have certain diabetes-related antibodies, detectable C-peptide levels, and no history of severe diabetic complications or other serious health conditions. Pregnant teens or those at risk of pregnancy without contraception are excluded.

What is being tested?

The study tests whether repeated BCG vaccinations can improve immune response and blood sugar control in young people with Type 1 diabetes. Participants will either receive the BCG vaccine or a saline injection as a placebo to compare effects.

What are the potential side effects?

BCG vaccination may cause local reactions like pain, redness, or swelling at the injection site. There's also a low risk of fever and mild flu-like symptoms following vaccination.
