ScRNA-seq, V(D)J seq, CITE-seq, LIBRA-seq of human CD4+, CD8+ and B lymphocytes PBMCs of 5 donors (3 SARS-CoV-2 experienced and 2 SARS-Cov-2 Naive) before and following two doses of Pfizer/BioNTech BNT162b2 mRNA vaccine

ABSTRACT: The experiment aims at characterizing the immune responses elicited by the BNT162b2 vaccine against SARS-CoV-2, initially administered in a two dose regimen (second dose after three weeks followinf the first dose) In particular the transcriptional landscape of circulating T and B lymphocytes has been profiled longitudinnaly by scRNA-seq coupleD with CITE-seq of 19 cell surface markers to better classify T cells subpopulations, LIBRA-seq to assess the Spike-specificity of BCRs and and V(D)J seq to also track T and B cell clones dynamics. Eeach sample was profiled before vaccination (T0), 21 days after the first dose (T1), 2 months after the first dose (1 month after the second dose) (T2). The immune responses were characterized using PBMC from 3 SARS-CoV-2 experienced donors (experiencing SARS-Cov-2 at least 4 months before the first vaccinatin) and 2 SARS-CoV-2 unexperienced donors.
