SARS-CoV-2 lymphocyte reactivity in TJR candidates. SARS-CoV-2 adaptive immunity was determined by lymphocyte transformation testing against SARS-CoV-2 nucleocapsid (A) and spike (B) proteins in TJR candidates (n=73). Lymphocyte stimulation index (SI) was achieved by normalizing nucleocapsid- and spike protein-treated lymphocyte counts per minute (cpms) to unchallenged lymphocyte controls. Each dot represents each subject tested and an SI > 2 was considered a positive reactive result
