SARS-CoV-2 infection during the Omicron surge among patients receiving dialysis: the role of circulating receptor-binding domain antibodies and vaccine doses.

Low circulating antibodies could identify the subgroup needing intensified surveillance, prophylaxis or treatment in this patient population.
