Little is known about the decay kinetics of coronavirus disease 2019 vaccine–elicited severe acute respiratory syndrome coronavirus 2–specific T cells. In this study we show a modest decline in the frequency of these T cells at 6 months and demonstrate robust expansion in response to antigen and recognition of spike peptides from the Delta variant.
