Fuck prions and the horse they rode in on.
They're not even alive, so you can't kill them. No vaccine, no cure, and thoroughly cooking your food is still no guaranteed way to get rid of them.
Nature's silent assassins, and they take their sweet time doing it too. By the time you first notice it's already far too late.
I say this without any attempt at humor, "kill yourself peacefully before you're unable to and the people around you refuse to"
If I knew I had a prion disease, I'd be making plans to die peacefully unaware, or suddenly, the moment a symptom shows up.
My only real firsthand experience with prion diseases is Fatal Familial Insomnia, and the person was strapped into hospital bed restraints after a suicide attempt, and the only thing they would do when they chose to speak was beg for us to let them die because they can't keep going like this anymore.
Edit: honestly I do not know if there is any way to treat other prions, but to my knowledge there isn't. It's just "ease their suffering as they slowly die in front of you"
Prion diseases are fatal infectious neurodegenerative disorders and prototypic conformational diseases, caused by the conformational conversion of the normal cellular prion protein (PrPC) into the pathological PrPSc isoform.
The immune system does not develop a bona fide immune response against prion infection, as PrPC and PrPSc share an identical protein primary structure, and prions seem not to represent a trigger for immune responses. This asks for alternative vaccine strategies, which focus on PrPC-directed self-antibodies or exposure of disease-specific structures and epitopes. Several groups have established a proof-of-concept that such vaccine candidates can induce some levels of protective immunity in cervid and rodent models without inducing unwanted side effects. This review will highlight the most recent developments and discuss progress and challenges remaining.
Have a read through the full article and sources below and you can take a look at some novel approaches being evaluated at the moment:
Well, viruses aren't alive either. I would say they are very similar to Prions in the aspect, that it is just a rogue biological building block, able to get itself reproduced, to the dismay of the body.
Also there is no reason, why you couldn't develop vaccines against Prions. It could be even simpler, because they have to be shaped very specifically to cause the harm they do, and it should be easy to break that specific shape with something attaching to it.
Prions are gone rogue, by being shaped a different way. They are uniquely different from their original protein. At the end of the day Viruses are also just normal DNA that went rogue and changed over time. The difference is that viruses can spread and mutate much more easily, so they could adapt under evolutionary mechanisms.
if you are infertile, then early or late does not matter
either way, the individual "you" does not matter to evolution that works on a population basis (not strictly speaking fully true bc of e.g. bottlenecks, like Mitochondrial Eve, Y-chromosomal Adam, and Genghis Khan, but the idea of "population" can be extended to include such founder effects). i.e. your genetic makeup is determined by millions of years of prior evolution, not what you had for breakfast this morning, so regardless of current fertility status, events such as Alzheimer's are "okay" (again, caveat: purely in the evolutionary sense - though it is horrifying to an individual who gets it) bc they occur post reproductive age, i.e. it is too late bc the genes have already been passed on to another generation.
Insert additional caveats to literally all of this, and also caveats to those caveats, bc biology cares little for how easily it can be understood:-D. e.g. kin selection is also a thing, long past reproductive age and also works for infertile people.
