Prions and Creutzfeldt‐Jakob disease

There's a new antivaccine talking point in town, and it's just as much disinformation as other antivaccine talking points. 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.
