SARS-CoV-2 breakthrough infection induces rapid memory and de novo T cell responses

Our understanding of T cell responses to SARS-CoV-2 vaccination and breakthrough infection has lagged behind B cells and antibodies. Here, Koutsakos et al utilize longitudinal sampling to demonstrate rapid activation of SARS-CoV-2-specific CD4+ and CD8+ T cells during breakthrough infection. Furthermore, Spike-specific CD8+ T cell activation correlates with viral clearance.
