Once you get prions you're DAID. Nobody lasts very long. So the prions are in the shots, it seems.
The other option, if this continues to be a trend, is that there may be many people with this as an underlying but highly delayed condition. We already know that the expected massive wave of people dying from CJD in the 2000s didn't happen, yet many, especially in the United Kingdom, were exposed.
We won't know without serious and honest studies, but it would not surprise me if CJD, like Toxoplasmosis, can hide for decades, maybe even an entire lifetime, in the body until something kicks it off.
I've suspected for a long time that one thing the mRNA shots MAY be doing is kicking pre-existing conditions and genetic tendencies into overdrive. With "Toxo," that disease tends to go full tilt if the immune system is damaged or destroyed (this was first noticed during the HIV epidemic). With CJD, it may be either a blasted immune system or an immune system sent into overdrive by the vaccines (or sometimes even COVID itself).
It could also be inside the shots. I am not saying that it isn't. But if there is a link between CJD and vaccines, then a deep study is needed to determine what is going on. Sadly, that isn't likely to happen anytime soon.
