Animals have always been used in biological and medical research. AAVS proposes that this is more a matter of tradition than one of need. Animal research has never proven to be better than other models, nor particularly successful at all.
In fact, the use of animal ‘models’ has never been validated, and the claim that animals are necessary for biomedical research, is unsupported by scientific literature. There is, rather, growing awareness of the scientific limitations of animal research and its inability to make reliable predictions about human health.
This, paired with the ethical case against animal use, is why the biomedical community would be best served by the development of non-animal models that overcome the limitations of an increasingly archaic system of animal experimentation.
