Biomarkers of protection against controlled human SARS-CoV-2 Delta variant breakthrough infection

2026-07-28

Abstract excerpt

<h4>Background</h4> Improved understanding of how variants cause breakthrough infection, despite pre-existing immunity, is needed to advance development of next-generation SARS-CoV-2 vaccines, including those that may provide cross-variant protection or block transmission. SARS-CoV-2 controlled human infection models (CHIMs) may therefore identify correlates of protection and accelerate the development of new int...
