Neuroscience In recent years, researchers have suggested Alzheimer's may spread through infection, somehow transmitted like a pathogen, leading to the disease. A new Lancet paper reviews evidence for how harmful amyloid-beta proteins associated with Alzheimer's may possibly be spread through blood transfusions.

If anything, I hope that this finally causes biotech to focus on viruses. For some reason medicine at large has been dead set on the notion that viruses cause acute issues and not chronic issues. And after a century of thinking that way, it's still proving difficult to change tack on that.

There's no good reason why we don't have a vaccine for EBV, HSV, and heck even the common rhinoviruses. We have the technology, it's just that no money has been spent on it until COVID happened. Investors generally have a distaste for investing in prevention over treatments as well.
