The Vervet Monkey has been the focus of quite a bit of scientific research dating back to the 1950s. The tissue of these species is actually still used today in the production of the polio and smallpox vaccinations. There is also ongoing research involving the cells of the Vervet monkey kidney in relation to immunology and infectious diseases.
