Abstract
We developed two quantitative PCR-based assays to detect SARS-CoV-2-specific T cell immunity: qTACT and dqTACT. The assays quantify CXCL10 mRNA, after incubation of whole blood with viral peptides, as a proxy of an antigen-specific T cell response, and will allow population-level monitoring of cellular immunity to SARS-CoV-2.
