A study highlighted a case of a previously healthy 38-year-old woman diagnosed with precursor B-lymphoblastic leukemia/lymphoma weeks after receiving her second mRNA COVID-19 vaccine dose. The research reviewed 30 publications reporting malignancies post-vaccination, predominantly lymphoid neoplasms. Despite mild leukopenia before vaccination, the researchers noted this could indicate a benign condition rather than leukemia. They found associations between vaccination and increased cancer-related hospitalizations, emphasizing the need for cautious interpretation of their findings around potential links between vaccination and oncogenesis.
