“We don’t want to use animals, but we don’t have any other options.”
Human clinical and epidemiological studies, human tissue- and cell-based research methods, cadavers, sophisticated high-fidelity human patient simulators and computational models are more reliable, more precise, less expensive, and more humane than animal experiments. Progressive scientists have used human brain cells to develop a model “microbrain,” which can be used to study tumors, as well as artificial skin and bone marrow. We can now test irritancy on protein membranes, produce and test vaccines using human tissues, and perform pregnancy tests using blood samples instead of killing rabbits. Animal experiments don’t persist because they are the best science, they persist because of experimenters’ personal biases and archaic traditions.
