Lymphoma Patients' vaccine response under scrutiny

NCT ID NCT05050461

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at how well the COVID-19 vaccine works in adults with B-cell non-Hodgkin lymphoma, especially those who received a common treatment called anti-CD20 monoclonal antibodies in the past year. Researchers compared antibody and T-cell responses between treated and untreated patients to understand if prior therapy weakens vaccine protection. The goal was to guide future vaccine and treatment recommendations for this vulnerable group.
