Abstract

We assessed vaccine-induced antibody responses to the SARS-CoV2 ancestral virus and Omicron variant before and after booster immunization in 57 patients with B-cell malignancies. Over one third of vaccinated patients at the pre-booster timepoint were seronegative, and these patients were predominantly on active cancer therapies such as anti-CD20 monoclonal antibody. While booster immunization was able to induce detectable antibodies in a small fraction of seronegative patients, the overall booster benefit was disproportionately evident in patients already seropositive and not receiving active therapy. While ancestral and Omicron-reactive antibody levels among individual patients were largely concordant, neutralizing antibodies against Omicron tended to be reduced. Interestingly, in all patients, including those unable to generate detectable antibodies against SARS-CoV2 spike, we observed comparable levels of EBV and influenza reactive antibodies demonstrating that B cell-targeting therapies primarily impair de novo but not pre-existing antibody levels. These findings support rationale for vaccination prior to cancer treatment.
