Primary outcomePrimary: The Proportion of Participants With and Without Antibodies to SARS-CoV-2 — 875; 378; 277; 1825 Participants
Summary
DESIGN Observational epidemiological study
AIMS - To determine:
1. The proportion of immunosuppressed people who have detectable SARS-CoV-2 antibodies following a primary vaccine course (3 doses), and the demographic, disease, and treatment characteristics that influence antibody status.
2. If the detection of antibodies inversely correlates with subsequent risk of severe acute respiratory syndrome coronavirus-2 infection and/or severity of disease in immunosuppressed people.
