Serological assessment of SARS-CoV-2 infection during the first wave of the pandemic in Louisville Kentucky
Abstract Serological assays intended for diagnosis, sero-epidemiologic assessment, and measurement of protective antibody titers upon infection or vaccination are essential for managing the SARS-CoV-2 pandemic. Serological assays measuring the antibody responses against SARS-CoV-2 antigens are readi...
