Alzheimer's Vaccine Shows Promise

The BBC reports on the longer term results of 2002 trial for an Alzheimer's vaccine, a way of inducing the body to attack beta amyloid: "Results from the long-term follow up studies show 59 out of 300 patients who received at least one dose of the vaccine produced a significant immune response. This group performed significantly better on a series of memory tests than those who received a dummy injection. Brain scans also showed that their brains shrank in size - possibly because of a removal of built-up beta amyloid deposits." More sophisticated vaccine trials are already underway - this seems to be a promising approach to date, all told.
