Welfare of Captive Chimpanzees in Sanctuaries After Research

Chimpanzees retired from biomedical research face lifelong welfare challenges in sanctuary settings, often carrying trauma and health consequences of their research histories.

Key Facts

The US ended invasive chimpanzee research in 2015, releasing approximately 700 animals to sanctuaries
Research chimpanzees often have PTSD-like symptoms including hyperarousal, social withdrawal, and fear responses
Re-socialization of isolated research chimpanzees is a complex, years-long process
Chimpanzee sanctuary care costs approximately 16,000 USD per animal per year
Some facilities that used chimpanzees in research have refused to fund their lifetime sanctuary care

Welfare Considerations

Research-retired chimpanzees carry the welfare consequences of decisions made before they were born. Bred for biomedical research, subjected to procedures impossible under contemporary ethical standards, and then retired to sanctuaries that must address decades of trauma — these individuals represent the endpoint of an era in research that the scientific community has since recognized as ethically unjustifiable. Their remaining decades deserve the best possible sanctuary care, funded by those who benefited from the research.

What You Can Do

Support chimpanzee sanctuaries that care for research-retired individuals
Advocate for legal requirements that research institutions fund lifetime sanctuary care for chimpanzees they used
Donate to organizations providing trauma-informed rehabilitation for research-retired chimpanzees
Raise awareness of research chimpanzee welfare needs in discussions about biomedical research history
