HCW = healthcare worker, COVID-19 = coronavirus disease 2019, SARS-CoV-2 = severe acute respiratory syndrome coronavirus-2, ELISA = enzyme-linked immunosorbent assay, PCR = polymerase chain reaction, N/A = not available, OD = optical density.

^aIf 2 or more of the test results were positive, it was determined as positive for the antibody against SARS-CoV-2.
