Key Points

This research aims to enhance the accuracy of lineage-specific vaccine effectiveness estimates by addressing biases in test-negative designs.
Utilized test-negative designs (TND) to evaluate vaccine effectiveness against SARS-CoV-2 variants.
Employed lineage assignment methods including sequence-based, proxy-based, and period-based approaches.
Identified analytic considerations for robust estimation of vaccine effectiveness.
Demonstrated significant impacts of biases associated with different lineage assignment methods.
Provided guidance that may improve the estimation of vaccine effectiveness against other pathogens with antigenic drift.

Abstract

TND studies using sequence-, proxy-, and period-based lineage assignment have contributed substantially towards understanding SARS-CoV-2 variant-mediated vaccine escape, but biases that can affect each study design vary. Our results identify analytic considerations for robust estimation and suggest principles that may translate to other pathogens that undergo continuous antigenic drift.
