Can a shingles vaccine and diabetes drug save insulin cells?

This study tests whether the shingles vaccine Shingrix and the diabetes drug semaglutide, alone or together, can help preserve the body's ability to make insulin in adults recently diagnosed with type 1 diabetes. The goal is to slow the immune attack on insulin-producing cells and protect them from damage. About 240 adults aged 18 to 50 who were diagnosed within the last 100 days will take part. The main measure is how well the pancreas responds to a meal test after one year.
