Testing in mice has shown that the vaccine safely prevents the buildup of substances in the brain associated with the fatal disease.
…If the vaccine proves safe and effective in humans it could slice the number of dementia diagnoses in half, the study’s senior author told USA TODAY.
Dementia is a term used to broadly describe symptoms of cognitive decline; Alzheimer’s disease is the most common cause of dementia.
…The vaccine works by prompting the body to produce antibodies inhibiting the buildup of amyloid and tau, two proteins that are hallmarks of the degenerative brain disease.
The vaccine is one of several promising treatments aimed at reducing the buildup of those substances before they become deadly plaques and tangles in the brain.
