In a recent meta-analysis1,2 posted on preprints.org, Japanese researchers warn of potentially deadly risks to patients who receive blood from people who have taken mRNA COVID jabs and call for urgent action to ensure the safety of the global blood supply. According to the authors:3

"… many countries around the world have reported that so-called genetic vaccines, such as those using modified mRNA encoding the spike protein and lipid nanoparticles as the drug delivery system, have resulted in post-vaccination thrombosis and subsequent cardiovascular damage, as well as a wide variety of diseases involving all organs and systems, including the nervous system …

[B]ased on these circumstances and the volume of evidence that has recently come to light, we call the attention of medical professionals to the various risks associated with blood transfusions using blood products derived from people who have suffered from long COVID and from genetic vaccine recipients, including those who have received mRNA vaccines, and we make proposals regarding specific tests, testing methods, and regulations to deal with these risks."

Blood From Jabbed Donors May Pose Risk to Neurological Health

One particular risk addressed in this paper is the implications of blood tainted with prion-like structures found within the spike protein. Prions are misfolded proteins that can cause neurodegenerative diseases, such as Creutzfeldt-Jakob Disease (CJD) in humans, by inducing the misfolding of normal proteins in the brain.
