ANTWERP, BELGIUM — A recent scientific study published in the journal Frontiers in Oncology links the Pfizer-BioNTech COVID-19 vaccine to the development of aggressive cancer.
In the study, which was performed by Belgian scientists led by Dr. Sander Eens, 14 mice received two injections with the vaccine plus a booster. One of the mice rapidly developed an aggressive type of B-cell lymphoma and died shortly after the booster injection.
“Two days following booster vaccination (i.e., 16 days after prime), at only 14 weeks of age, our animal suffered spontaneous death with marked organomegaly and diffuse malignant infiltration of multiple extranodal organs (heart, lung, liver, kidney, spleen) by lymphoid neoplasm,” the authors state.
According to the scientists, rapid-onset lymphoma has been reported in humans post vaccination.
“Our case adds to previous clinical reports on malignant lymphoma development following novel SARS-CoV-2 mRNA vaccination. Interestingly, we are the first to report a B-LBL subtype, with its occurrence in mouse allowing a detailed histopathological and immunohistochemical examination of the different organs involved.”
As the authors stress difficulty with proving the causal link between the mRNA injections and cancer, they call for increased vigilance:
“Although strong evidence proving or refuting a causal relationship between SARS-CoV-2 mRNA vaccination and lymphoma development or progression is lacking, vigilance is required, with conscientious reporting of similar cases and a further investigation of the mechanisms of action that could explain the aforementioned association,” Dr. Eens and his co-authors state.
