Type 1 and type 2 diabetes are associated with increased severity and mortality from respiratory virus infections, including SARS-CoV-2. Vaccination in the general population significantly reduces the risk of severe respiratory viral infection and triggers a strong, polyfunctional and lasting T cell response in healthy individuals. However, vaccine effectiveness in people with diabetes is unclear. Here we studied the magnitude and functional characteristics of vaccine-specific CD4+ and CD8+ T cell responses to the full vaccination protocol, and the recall response after a third booster dose of SARS-CoV-2 vaccine in people with type 1 and type 2 diabetes, and compared them to those of people without diabetes. We found defects in both CD4+ and CD8+ T cell memory maintenance and the functionality of the vaccine specific T cells in people with diabetes compared to people without. In those individuals with diabetes that harbored detectable vaccine-specific T cells, they displayed an unfocused, tolerogenic phenotype characterized by increased expression of IL-13 and IL-10 in T1D and T2D compared to people without diabetes. These results have implications for vaccination strategies for people with diabetes.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
