A human monoclonal antibody from hybrid immunity exhibits exceptional neutralization breadth against antigenically divergent contemporary Omicron JN.1 lineage variants
It is found that among individuals with hybrid immunity who developed robust, durable antigen-specific antibody responses, one developed antibody response capable of broadly cross-neutralising contemporary Omicron variants.
A considerable variability in the potential of H5 vaccine antigens to induce neutralisation breadth is demonstrated, as well as the potential for multivalent vaccines and ferritin nanoparticle-based strategies to robustly augment immunity across antigenic variants.

The continued antigenic evolution of SARS-CoV-2 Omicron subvariants has progressively eroded vaccine-elicited protective immunity, driving demand for next-generation candidates that confer broad-spectrum protection against phylogenetically divergent strains. Here we report the design and preclinical evaluation of SV, a...
G germline revertant analysis of the COV2-3731 mAb provided additional insights into how this COV2-3731 and other IGHV3-53/3-66-encoded public antibodies evolve to gain breadth against antigenically distinct SARS-CoV-2 variants such as BA.2.3.2, BA.3.1, KP.2.2, and, to some extent, KP.3.3.2.

It is demonstrated that post-pandemic sera exhibit enhanced cross-neutralizing antibody responses predominantly against sarbecoviruses, potentially strengthening population immunity against related zoonotic sarbecoviruses and increasing the immunological barrier to their emergence in humans.

The observed waning of cross-neutralizing antibodies against emerging variants underscores the challenge of maintaining durable protection and supports the need for continued monitoring of antibody responses to guide evidence-based updates to COVID-19 vaccines.

The data show that complement potentiates the ability of antispike antibodies to neutralize immune-evasive SARS-CoV-2 variants and in sera from individuals with severe COVID-19, both complement-mediated neutralization and anti-S2 antibody levels were associated with improved survival.
