It is unclear whether prior endemic coronavirus infections affect COVID-19 severity. Here, we show that in cases of fatal COVID-19, antibody responses to the SARS-COV-2 spike are directed against epitopes shared with endemic beta-coronaviruses in the S2 subunit of the SARS-CoV-2 spike protein. This immune response is associated with the compromised production of a de novo SARS-CoV-2 spike response among individuals with fatal COVID-19 outcomes.<br><br>Funding: This work was supported by the Georg and Emily von Opel Foundation, the National Institute for Health Research (NIHR) [award CO-­‐CIN-­‐01], the Medical Research Council [grant MC_PC_19059], ME was supported by The Leona M. and Harry B. Helmsley Charitable Trust on May 31, 2021 for the project titled, "ICARUS –IBD: International study of COVID-­‐19 Antibody Response Under Sustained immune suppression in Inflammatory Bowel Disease. RP also supported by funds provided under Professor RW Snow’s Wellcome Trust Principal Fellowship (# 212176). Meso Scale Diagnostics (USA) provided loan of equipment, reagents and technical support. JSB was supported by funding from the Biotechnology and Biological Sciences Research Council (BBSRC) [grant number BB/M011224/1]. CPT was funded by an ERC research grant UNIFLUVAC’ and two MRC CiC grants (Ref: BR00140). ALM is funded by a NIHR Research Capability Funding grant.
