Studies suggest a link between an incurable and fatal prion disease known as Creutzfeldt-Jakob Disease (CJD) and COVID-19 vaccines.
Researchers believe the prion region from the original Wuhan COVID-19 variant’s spike protein was incorporated into mRNA vaccines and adenovirus vector vaccines — given to hundreds of millions of humans — and that it can cause a new type of rapidly progressing sporadic CJD.
According to Mayo Clinic, CJD is a degenerative brain disorder that leads to dementia and, ultimately, death. Although the Omicron variant does not have a prion region on its spike protein, current COVID-19 vaccines still use the genetic material — including the prion region — of the parent Wuhan strain.
