How did the National Institutes of Health funding come about?
The funding became available through the CHIMP (Chimpanzee Health Improvement, Maintenance and Protection) Act, a law passed by the US Congress on December 22, 2000. The Act provides funding for chimpanzees no longer used in biomedical research. The law was the outcome of years of lobbying by many diverse groups who support the concept of retirement for research chimpanzees.
