Mutations of SARS-CoV-2 variants of concern escaping Spike-specific T cells

N. Le Bert, A. T. Tan, K. Kunasegaran, A. Chia, N. Tan, Q. Chen, S. K. Hang, M. D. Qui, B. S. Chan, J. G. Low, B. Young, K. C. Ng, D. W. S. Chan, D. C. B. Lye, A. Bertoletti

This study examines how mutations in SARS-CoV-2 variants affect Spike-specific T cell responses, finding that some mutations reduce CD8 T cell recognition while overall T cell responses remain largely intact.
