Read our Diabetes Mellitus, Type 1 research guide →Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
Type 1 diabetes happens when the immune system mistakenly attacks cells in the pancreas that make insulin. This trial is testing whether the influenza vaccine (Vaxigrip Tetra) might help train the immune system to stop this attack and preserve the pancreas's ability to make insulin. Researchers believe this simple, affordable approach could reduce the severity of diabetes and help newly diagnosed patients maintain better control of their blood sugar.
Children who still produce some of their own insulin have far fewer dangerous blood sugar crashes and need less insulin medication overall. Right now, there's no simple treatment to slow down the immune system's attack on insulin-producing cells. This trial explores whether this medication might offer an affordable, accessible way to preserve the pancreas's remaining function and improve quality of life.

You will be randomly assigned to receive either the flu vaccine or a placebo (saline injection) as a single 0.5 mL shot. Researchers will then monitor your pancreas's insulin production, test your blood for markers of autoimmune activity, and check your disease severity over time. The trial will help doctors understand whether this simple vaccination can preserve your body's natural ability to make insulin.
