ImportanceIt has become common practice to offer immunocompromised patients with hematologic cancers a third COVID-19 vaccination dose, but data substantiating this are scarce.ObjectiveTo assess whether a third mRNA-1273 vaccination is associated with increased neutralizing antibody concentrations in immunocompromised patients with hematologic cancers comparable to levels obtained in healthy individuals after the standard 2-dose mRNA-1273 vaccination schedule.Design, Setting, and ParticipantsThis prospective observational cohort study was conducted at 4 university hospitals in the Netherlands and included 584 evaluable patients spanning the spectrum of hematologic cancers and 44 randomly selected age-matched adults without malignant or immunodeficient comorbidities.ExposuresOne additional mRNA-1273 vaccination 5 months after completion of the standard 2-dose mRNA-1273 vaccination schedule.Main Outcomes and MeasuresSerum immunoglobulin G (IgG) antibodies to spike subunit 1 (S1) antigens prior to and 4 weeks after a third mRNA-1273 vaccination, and antibody neutralization capacity of wild-type, Delta, and Omicron variants in a subgroup of patients.ResultsIn this cohort of 584 immunocompromised patients with hematologic cancers (mean [SD] age, 60 [11.2] years; 216 [37.0%] women), a third mRNA-1273 vaccination was associated with median S1-IgG concentrations comparable to concentrations obtained by healthy individuals after the 2-dose mRNA-1273 schedule. The rise in S1-IgG concentration after the third vaccination was most pronounced in patients with a recovering immune system, but potent responses were also observed in patients with persistent immunodeficiencies. Specifically, patients with myeloid cancers or multiple myeloma and recipients of autologous or allogeneic hematopoietic cell transplantation (HCT) reached median S1-IgG concentrations similar to those obtained by healthy individuals after a 2-dose schedule. Patients receiving or shortly after completing anti-CD20 therapy, CD19-directed chimeric antigen receptor T-cell therapy recipients, and patients with chronic lymphocytic leukemia receiving ibrutinib were less responsive or unresponsive to the third vaccination. In the 27 patients who received cell therapy between the second and third vaccination, S1 antibodies were preserved, but a third mRNA-1273 vaccination was not associated with significantly enhanced S1-IgG concentrations except for patients with multiple myeloma receiving autologous HCT. A third vaccination was associated with significantly improved neutralization capacity per antibody.Conclusions and RelevanceResults of this cohort study support that the primary schedule for immunocompromised patients with hematologic cancers should be supplemented with a delayed third vaccination. Patients with B-cell lymphoma and allogeneic HCT recipients need to be revaccinated after treatment or transplantation.Trial RegistrationEudraCT Identifier: 2021-001072-41
