Researchers at the University of Mexico are working on a vaccine they hope could prevent Alzheimer’s disease, CBS News reported.

The group started the work in 2013, according to KRQE.

The TV station reported UNM's Health and Sciences Department Associate Professor Kiran Bhaskar and his team started to test the vaccine on mice. It has not been shown if it works on people.

PhD student Nicole Maphis told KRQE the vaccine targets a specific protein known as tau that is often found in the brains of Alzheimer’s patients.

The group gave the mice a series of maze-like tests. The mice that received the vaccine performed much better than those that hadn't.

Drugs that work in mice do not always have the same effect on humans. It would cost the UNM Health Science Department about $2 million to test a small group of people.

KRQE reports Bhaskar and Maphis are looking for partnerships to help them get their goal of getting a clinical grade vaccine.

The Centers for Disease Control and Prevention says Alzheimer’s disease is the most common type of dementia. Doctors still don’t know what causes the disease. There is currently no known cure for Alzheimer’s disease.
