Antibody response in patients with immunocompromise after receiving the third SARS-CoV-2 vaccine via the Elecsys S test from Roche. SARS-CoV-2 spike protein receptor-binding domain antibody levels in patients who received the third SARS-CoV-2 vaccine and provided a blood sample at follow-up: people living with HIV with CD4 cell counts <350 or >350 cells/μL and recipients of kidney or lung solid organ transplantation. A value corresponding to half the detection limit (0.2 U/mL) is assigned to measurements below the detection limit (<0.4 U/mL). Horizontal black line, median; box, lower and upper quartiles; whiskers, all samples lying within 1.5 times the IQR.
