If mRNA “vaccines” do indeed cause prion brain diseases, it would be the scariest aspect of those vaccines so far. From 2nd Smartest Guy in the World at 2ndsmartestguyintheworld.com:
VAIDS biowarfare.
The genetically modified humans are suffering from VAIDS.
Perhaps the single most horrifying feature of these slow kill bioweapon “vaccines” is found in the prion disease symptom of VAIDS that is transmittable.
This latest communicable mis-folded protein disease may not just spread through, say, intercourse, but, rather, far more worryingly, it may be transmitted via airborne particles as well as casual physical contact.
Doctors warn mRNA vaccines could spur epidemic of prion brain diseases

The overriding question that now remains is did the Intelligence Industrial Complex and their partners-in-crime like BigPharma, the UN, WEF, CFR, WHO, NIH, FDA, CDC, et al. know that their Modified mRNA “vaccines” would induce prion diseases.
Longtime readers of this Substack already know the answer to this crucial question.
Let us consider the following article from 2019 that was written by a trio of DoD/USSOCOM/DARPA scientists, more at biowarfare criminals conducting illegal research as paid for via grants stolen from taxes, in the Deep State journal Defence iQ entitled, Prions as Bioweapons?
