Thus, further investigations are warranted to determine the balance between protective and tolerogenic functions of vaccine‐specific T cell‐derived IL‐10 and IL‐13 in people with diabetes and to unambiguously define the involvement of IL‐10 and IL‐13 in the maintenance and function of vaccine‐specific T cell responses, as well as their favorable or detrimental role in antiviral immunity upon infection in diabetes. The gene discussed is IL10; the disease is diabetes mellitus.
