Great news!!! 300+ chimpanzees have been retired to Chimp Haven, the world's largest chimpanzee sanctuary representing the end of their use in biomedical research!!!  The National Institutes of Health (NIH) facilitated the retirement of these chimps, ending their use in research. 

They are free to live their lives in a natural environment similar to what they would have in the wild.  The sanctuary model emphasizes the need for ethical treatment and long-term care for these animals, reflecting a growing recognition of their sentience and emotional needs.
