Should researchers be allowed to use animals in testing the safety of drugs, vaccines, medical devices, and cosmetics?

Animal testing is the use of non-human animals in experiments that seek to control the variables that affect the behavior or biological system under study. Examples of applied research include testing disease treatments, breeding, defense research, and toxicology, including cosmetics testing. In education, animal testing is sometimes a component of biology or psychology courses. There is no nationwide ban on animal testing in the United States. The humane society estimates that more than 50 million dogs, cats, monkeys, rabbits, rats and other animals undergo testing each year in the US.
