Rapid Progression of Angioimmunoblastic T Cell Lymphoma Following BNT162b2 mRNA Vaccine Booster Shot: A Case Report


And it still advertises some benefit over the not-so-experimental cocktails.

Since nucleoside-modified mRNA vaccines strongly activate T follicular helper cells, it is important to explore the possible impact of approved SARS-CoV-2 mRNA vaccines on neoplasms affecting this cell type. Herein, we report and discuss unexpected rapid progression of lymphomatous lesions after administration of a BNT162b2 mRNA vaccine booster in a man recently diagnosed with AITL.


Introduction


The remarkable efficiency of nucleoside-modified SARS-CoV-2 mRNA vaccines has been related to their ability to induce a potent stimulation of T follicular helper (TFH) cells, resulting in persistent germinal center B cell responses (1, 2). Clinically, this might translate into reactive lymphoadenopathy which sometimes may raise a differential diagnosis with a lymphoproliferative disorder (3, 4). At the same time, the possible impact of SARS-CoV-2 mRNA vaccination on pre-existing peripheral T cell lymphoma is still to be determined.
