Vaccine-induced donor-specific HLA antibodies: a case report highlighting sensitization risks in renal transplant waitlisted patients

RZV or PCV13 vaccines or their adjuvant components can potentially cause allosensitization in renal transplant waitlisted patients. The detection of DSA can result in reduced access to compatible transplants. With advances in HLA immunogenetics, better tools can monitor HLA-specific memory B-cells to provide crucial insights into the primary mechanism of action of HLA DSA antibody formation and suggest interventions to mitigate this memory B-cell activation.
