COVID-19 vaccines, prion disease, and Alzheimer’s: Another old antivax lie is new again

Antivax immunologist J. Bart Classen recently published a paper claiming that mRNA-based COVID-19 vaccines can cause prion disease leading to neurodegenerative diseases like Alzheimer’s dementia.

It’s the claim that mRNA COVID-19 vaccines are not really vaccines but “medical devices,” “gene therapy,” or “experimental biologics” and that they were falsely classified as vaccines in order to bypass safety testing. Here, we discuss why this claim is utter nonsense based on the highly deceptive use of terminology.
