C, Comirnaty; ICU, intensive care unit; IvIg, intravenous immunoglobulin; iwCLL, International Workshop on Chronic Lymphocytic Leukemia; PD, progressive disease; PR/CR, partial remission/complete remission; S, Spikevax; SD, stable disease.

With no current treatment. All with anti-CD20 monoclonal antibody–containing immunochemotherapy (bendamustine-rituximab/fludarabine-cyclophosphamide-rituximab) and all >12 months prior to vaccination.

Both with BTKi (ibrutinib). One was previously treated with immunochemotherapy >12 months ago and stopped ibrutinib therapy shortly after the second vaccine dose.

Number of patients at each time point is shown in Figure 1 and supplemental Figure 1.

Comirnaty (BNT162b2, Pfizer BioNTech), Spikevax (mRNA-1273, Moderna). Two patients did not receive dose 3.
