Repeated mRNA vaccination and breakthrough infection reveal durable dominance but diminishing recall of vaccine-induced CD8⁺ T-cell clones
{{output}}
Successive mRNA vaccinations preserve SARS-CoV-2-specific T-cell immunity, but how individual CD8⁺ T-cell clones behave across repeated booster doses and breakthrough infection (BTI) remains poorly defined. We longitudinally tracked bulk CD8⁺ TCRβ repertoir... ...
