We sought to independently verify this relationship between TCR sequence and persistence by comparing our contracting clonotypes with those from Minervina et al., who also identified SARS2-YLQ-specific CD8+ T cell clonotypes that contracted 2–3 months post-infection.8 Using TCR sequence similarity, we utilized those reported contracting clonotypes to predict which of our clonotypes would contract. Here, CD8A is linked to infection.
