BNT162b2 mRNA vaccination affects the gut microbiome composition of patients with follicular lymphoma and chronic lymphocytic leukemia.
Taken together, our findings reveal the effect of the BNT162b2 vaccine in shaping the microbiome composition in CLL and FL patients, despite receiving treatment for their underlying active disease, and highlight the importance of a comprehensive analysis of the immunome and microbiome profiling to understand immune function in these cohorts of patients.
