Demographic information for reinfection correlates of protection nested case-control cohort from AZHEROES/RECOVER, stratified by vaccination status.

<p><sup>a</sup>All vaccine doses are monovalent origin strain WA-1 mRNA vaccines. <sup>b</sup>Other essential workers include occupation sectors with potentially high exposures to SARS-CoV-2 such as education, agriculture, public transportation services, waste collection, delivery, utilities, community-based services, childcare, and others. <sup>c</sup>Chronic conditions include asthma, chronic lung disease, cancer, diabetes, heart disease, hypertension, immunosuppression, kidney disease, liver disease, neurologic or neuromuscular disease or disorder, and autoimmune disease. <sup>d</sup>Participants are asked “Are you currently taking prednisone or other ongoing steroid medications (excluding inhaled steroids and one-time injections) or any other medications that may suppress your body’s ability to fight infection?”. <sup>e</sup>ICE (immune conferring event) is the third vaccine dose for the first-time post-vaccination infection with Omicron cohort and the 3 dose strata within the reinfection cohort, the second vaccine dose for the 2 dose strata within the reinfection cohort, and the initial SARS-CoV-2 infection for the unvaccinated strata within the reinfection cohort. <sup>f</sup>Exposure to individuals infected with SARS-CoV-2. <sup>g</sup>Reported personal protective equipment (PPE) adherence at work was defined as the percentage of time in which an individual uses the PPE recommended by their employer when in direct contact with people.</p> <p>(DOCX)</p>
