Trial of Alzheimer's vaccine is successful



The new treatment, which is presented in Lancet Neurology, involves active immunization, using a type of vaccine designed to trigger the body’s immune defense against beta-amyloid. In this second clinical trial on humans, the vaccine was modified to affect only the harmful beta-amyloid.
The researchers found that 80 per cent of the patients involved in the trials developed their own protective antibodies against beta-amyloid without suffering any side-effects over the three years of the study.
