Type 1 diabetes is an autoimmune disease where the immune system attacks and destroys insulin-producing cells in the pancreas, causing sugar to build up in the bloodstream. There is no cure, though there are treatment options.

Inverse vaccinations can affect the entire immune system, so scientists have been studying antigen-specific vaccines. Several vaccines are already in trials.
