Medical Research shouldn't be tested on animals because it doesn't give accurate results on how the human body would react to a new medicine. "A major reason for these failures is that most new drugs are first tested out in mice, rats or other animals."(Harris,Drugs That Work In Mice Often Fail When Tried In People) Not only does animal testing not give accurate results but millions of animals die because of these tests that they are forced to endure. They don't need to endure that pain they are being put through since there are alternatives that will produce accurate results. Such as testing cells and tissues in test tubes or cell cultures, 3D tissue culture also referred to as organs-on-a chip, Computational and mathematical models, Stem cell research, Non invasive diagnostic imaging, and Clinical research involving people.
