abstract = {We describe the T-cell response of two healthy
SARS-CoV-2-unexposed volunteers to a SARS-CoV-2
nucleoprotein-derived vaccine peptide predicted to
promiscuously bind multiple HLA-DR allotypes. NGS-based bulk
TCR-repertoire analysis of peptide-specific T-cell responses
4 (D2) and 27 (D1) weeks after vaccination identified CDR3
regions of TCRα, -β, -γ and -δ chains in T cells
responding ex-vivo to the vaccine peptide LLLLDRLLNQLESKMS
with IFNγ+-secretion. Adaptive repertoires were unique.
Donors shared 15 TCRα and 9 TCRβ clonotypes, all public,
showing no conserved motifs but TdT-independent 'neonatal'
CDR3 regions close to the germline. Half the wtSARS-CoV-2
nucleocapsid-reactive adaptive clonotypes show preferential
V-segment usage (6/64 Vα and 4-8/45 Vβ chains), and all
share/show a N-nucleotide-encoded hydrophobicity in their
CDR3 region. VδCα rearrangements $(20.4\%$ and $15.3\%$ of
the TCRα-repertoires, respectively), Vδ1Cδ
γδ-clonotypes homologous to public CD1-restricted Vδ1+
γδTCRs, and the induction of 'adaptive' Vδ2Vγ9negative T
cells support the role of innate T cells in the immune
response.},
