The scientists, who have been working on an Alzheimer's vaccine for years, say they have moved on to human clinical trials.

The vaccine was successfully tested in animals, and now, they need to make sure it is safe for humans.

It works by creating antibodies that attack a protein that has been linked to Alzheimer's.

The scientists say they do not want to raise false expectations, but hope for positive results from the clinical trials.
