Elan’s Alzheimer’s vaccine shows positive signs, study finds

ELAN’S experimental Alzheimer’s vaccine, which was pulled from testing after it caused serious side effects, stopped and even reversed the brain disease in some patients a study published in the journal Neuron reveals.

The vaccine’s developers, Elan and Wyeth, have stopped testing of the drug, which was designed to pit the immune system against the debilitating ailment.

The drug caused brain inflammation in 18 of 300 patients who received injections, although the positive findings suggest that similar vaccines under development may be able to save people from the syndrome’s dementia and loss of memory.
