SARS-CoV-2-specific T cell immunity is seen in cases of COVID-19
SARS-CoV-2-specific T cell immunity in cases of COVID-19 and SARS, and uninfected controls: Memory T cells induced by previous pathogens can shape the susceptibility to, and clinical severity of, subsequent infections1. Little is known about the presence of pre-existing memory T cells in humans with...
