NBC NEWS — Today is World Alzheimer's Day, and Spanish scientists say they've started human clinical trials on an Alzheimer's vaccine.
It's been successfully tested in animals and now they need to make sure it's safe for humans.
It works by creating antibodies that attack a protein that has been linked to the disease.
The scientists say they don't want to raise false expectations, but hope for positive results from the clinical trials.
