Proposal for a vaccination strategy in patients on dialysis.aAn adequate response to vaccination can be defined as antibody levels above a certain antibody threshold 4 weeks after vaccination, for example, 264 binding antibody units (BAUs)/ml.38 A low response can be defined by antibody levels >0 BAU/ml but <264 BAUs/ml. These thresholds need to be redefined for Delta and Omicron. The benefit of primary prophylaxis against variants of concern (VOCs) has not been demonstrated.
