Commentary on recent Alzheimer's research can be found over at FuturePundit. "Injected antibodies might avoid the side effects produced by vaccination against Alzheimer's amyloid plaques. ... While the Elan Pharmaceuticals experimental vaccine AN-1792 against Alzheimer's amyloid plaques caused brain inflammmation in a small subset of people treated I still think a better vaccine may be able to eventually work well against amyloid plaques. In fact, a new oral vaccine has just been tested in mice and shows promise." Some other good points are made regarding the payoff from investment in medical research - it's always better in the long term to be doing more to cure age-related degenerative conditions.
