Structured Abstract

Background

Uncertainty exists regarding the effectiveness of COVID-19 vaccine to prevent Post-Acute Sequelae of COVID-19 (PASC) following a breakthrough infection. While most studies using symptom surveys found an association between preinfection vaccination status and PASC symptoms, studies of medically attended PASC are less common and have reported conflicting findings.
