HCWs Post SARS-CoV-2 Vaccination Data

Additional data on vaccination, possible side effects, and a history of new SARS-CoV-2 infections were captured in an already existing REDCap® (Vanderbilt University) database. SARS-CoV-2 spike antibodies were determined using the Wantai® total spike antibody kit (Beijing Wantai Biological Pharmacy Enterprise, China) on an automated ELISA and chemiluminescent platform respectively. The Wantai® kit has a manufacturer’s reported sensitivity of 96.7% and a specificity of 97.5%.

Results from these tests were expressed semi-quantitatively as a signal-to-cut-off ratio (S/Co) for both assays. A S/Co value ≥ 1.0 was considered positive. Demographic, work related, clinical and laboratory data are in the spread sheet under the appropriate column headings.
