ABSTRACT
Nonhuman primates may well be the first recorded animal subjects for scientific research.1 Since that initial use, they have been utilized in many areas of biomedical and behavioral research where their similarity to humans makes them uniquely valuable animal models. Of particular note is the role that nonhuman primates have played in virological research and in the development and testing of important vaccines for diseases such as polio and hepatitis. They have also been used historically in the areas of reproductive physiology, behavior and learning, and neurophysiology.
