Spike-specific T cells are enriched in breastmilk following SARS-CoV-2 mRNA vaccination
13 Jan 2023
Abstract excerpt
Human breastmilk is rich in T cells; however, their specificity and function are largely unknown. We compared the phenotype, diversity, and antigen specificity of T cells in breastmilk and peripheral blood of lactating individuals who received SARS-CoV-2 messenger RNA (mRNA) vaccination. Relative to blood, breastmilk contained higher frequencies of T effector and central memory populations that expressed...
