Now that the “plaques are the disease” folks are having to listen to viable research in contradiction to them, there is a possible outcome that an mRNA vaccine for tooth decay ais also an mRNA vaccine for Alzheimer’s, if that particular theory pans out. Which would subtract a trillion dollars from GDP over a medium timescale. I remain hopeful :) but I’m not particularly holding my breath for the U.S. to invent a cure at this point, simply because of how much profit it will cost the booming industries of health insurance and elder care.
