Prion/virus the danger of biological weapons

If the attacking force has a vaccine before the attack, will inflict a crippling damage on the enemy. Thus, virus emerges as potential danger since they can be used in the development of such weapons. The reported of a neurotropic strain influenza A virus (IAV) induced the conversion of normal prion protein (PrPC) into infectious prion protein (PrPSc) as well as formation of infectious prions bring out the danger of a type of prion/virus as unprecedented infectious pathogens that cause fatal neurodegenerative diseases. Due to their singular characteristics a virus inducer of prion disease can be a stealth advantage for the attacker if he has an effective vaccine. Therefore, lethal prion/virus can be developed by malicious researchers who could use it to attack political enemies.
