8 Expert Quotes Admitting That Testing on Animals Is Unreliable

Experiments on animals are unethical—humans don’t have the right to imprison or harm animals. And such experiments don’t even work. Research shows that animal studies are failing to lead to treatments and cures, and they’re wasting time and resources.  Here’s what esteemed scientists, government officials, and physicians have to say about them:

“Traditional animal testing is expensive, time-consuming, uses a lot of animals and from a scientific perspective the results do not necessarily translate to humans.”

—Dr. Christopher Austin, former director of the National Institutes of Health (NIH) Chemical Genomics Center

Animal Research Quotes

“[M]ice are mice, and people are people. If we look to the mouse to model every aspect of the disease for man, and to model cures, we’re just wasting our time.”

—Dr. Clifton E. Barry, chief of the Tuberculosis Research Section at the National Institute of Allergy and Infectious Diseases

Animal Research Quotes

“We have moved away from studying human disease in humans. We all drank the Kool-Aid on that one, me included. … The problem is that [testing on animals] hasn’t worked, and it’s time we stopped dancing around the problem. … We need to refocus and adapt new methodologies for use in humans to understand disease biology in humans.”

—Dr. Elias Zerhouni, former director of the National Institutes of Health

Animal Research Quotes

“[Researchers] are so ingrained in trying to cure mice that they forget we are trying to cure humans.”

—Dr. Ronald W. Davis, professor at Stanford University

Animal Research Quotes

“[P]revention [of polio] was long delayed by the erroneous conception of the nature of the human disease based on misleading experimental models of the disease on monkeys.”

—Dr. Albert Sabin, developer of the oral polio vaccine

Animal Research Quotes

Animal Research Quotes

“Patients have been too patient with basic research. Most of our best people work [on] lab animals, not people. But this has not resulted in cures or even significantly helped most patients.”

—Dr. Ralph Steinman, former immunologist at Rockefeller University

Animal Research Quotes

Treating sentient beings as if they were inanimate lab tools is wrong, and it’s sloppy science. We’re working every day to end tests on animals, and our consistent victories speak for themselves.

We’re currently urging Texas A&M University to close its muscular dystrophy (MD) dog laboratory, release all the dogs in its lab for adoption into good homes, and redirect resources toward modern, humane research methods.
