Extended Data Fig. 7: Anti-spike IgG to human endemic coronaviruses.
From: Pre-existing polymerase-specific T cells expand in abortive seronegative SARS-CoV-2
Anti-spike IgG titres were measured post-infection (wk8, time of peak SARS-CoV-2 S1 IgG seropositivity in COVIDsortium HCW cohort) in HCW with laboratory-confirmed infection (n=20), and post-exposure (wk8) in SN-HCW with weak (<50 SFCs per 106 PBMCs, n=19) or strong RTC-specific T cell response at wk16 (n=19, >50 SFCs per 106 PBMCs). Red lines, geomean.
