Longitudinal dynamics of humoral immune responses following serial COVID-19 vaccinations and breakthrough infections in dialysis patients.

ABSTRACT: Patients with end-stage kidney disease (ESKD) undergoing dialysis have impaired vaccine responses. Many countries recommend extended primary series and regular COVID-19 boosters for this group, but data on long-term humoral responses after repeated doses or breakthrough infection are limited. In this prospective cohort study of 498 dialysis patients, most received homologous ChAdOx1 nCoV-19 as a primary series, mRNA-1273 for the third and fourth doses, and bivalent Moderna vaccines for later doses. Neutralizing antibodies (via surrogate virus neutralization test) and anti - receptor-binding domain (RBD) antibodies were measured up to 15 months post-vaccination or infection. The primary endpoint was seroprotection (neutralization inhibition ≥30%); the secondary was anti-RBD seroprotection (
