The unfocused and tolerogenic recall response to SARS‐CoV‐2 vaccination, dominated by the acquisition of IL‐10 and IL‐13 production by vaccine‐specific T cells from people with diabetes, is in contrast with the focused, TNF‐, IL‐2‐ IFNγ‐producing T cell response observed by us and others [28] in people without diabetes, where vaccination barely induced any Th2‐ or Th17‐type cytokine. This evidence concerns the gene IL2 and diabetes mellitus.
