Description
Sharon Walmsley and co-authors measure antibody defense against new COVID variants in a 2026 study. They followed 140 adults in a long vaccine study, with blood taken in late 2023 and spring 2024. Most had hybrid immunity from both shots and past infection.
Nearly all carried neutralizing antibodies against the original strain, but fewer could block the two newer Omicron sub-variants. Levels fell over time, fastest in the vaccine-only group and against the newest variant. Antibody level against that variant did not predict who caught COVID in the next ten months. The authors argue for broader, pan-coronavirus vaccines.
