Comparison of Omicron breakthrough infection versus monovalent SARS-CoV-2 intramuscular booster reveals differences in mucosal and systemic humoral immunity
Our understanding of the quality of cellular and humoral immunity conferred by COVID-19 vaccination alone versus vaccination plus SARS-CoV-2 breakthrough (BT) infection remains incomplete. While the current (2023) SARS-CoV-2 immune landscape of Canadians is complex, in late 2021 most Canadians had either just received a third dose of COVID-19 vaccine, or had received their two-dose primary series and then experienced an Omicron BT. Herein we took advantage of this coincident timing to contrast cellular and humoral immunity conferred by three doses of vaccine versus two doses plus BT. Our results show thatBT infection induces cell-mediated immune responses to variants comparable to an intramuscular vaccine booster dose. In contrast, BT subjects had higher salivary immunoglobulin (Ig)G and IgA levels against the Omicron spike and enhanced reactivity to the ancestral spike for the IgA isotype, which also reacted with SARS-CoV-1. Serumneutralizing antibody levels against the ancestral strain and the variants were also higher after BT infection. Our results support the need for the development of intranasal vaccines that could emulate the enhanced mucosal and humoral immunity induced by Omicron BT without exposing individuals to the risks associated with SARS-CoV-2 infection.
期刊介绍:
Mucosal Immunology, the official publication of the Society of Mucosal Immunology (SMI), serves as a forum for both basic and clinical scientists to discuss immunity and inflammation involving mucosal tissues. It covers gastrointestinal, pulmonary, nasopharyngeal, oral, ocular, and genitourinary immunology through original research articles, scholarly reviews, commentaries, editorials, and letters. The journal gives equal consideration to basic, translational, and clinical studies and also serves as a primary communication channel for the SMI governing board and its members, featuring society news, meeting announcements, policy discussions, and job/training opportunities advertisements.
