Primate Research Welfare: 3Rs and Species-Specific Needs

Overview of welfare requirements for non-human primates in research, and 3Rs progress.

Key Facts

Use of non-human primates in research is declining in some countries
Primates have complex social, cognitive, and emotional needs challenging to meet in labs
Social housing and outdoor access significantly improve primate research welfare
Replacement with cell cultures and organoids is advancing for some primate research questions
Ethical review of primate research is more rigorous than for most other species

Welfare Considerations

Non-human primate welfare in research represents one of the most ethically complex areas of animal research. Their cognitive and social complexity means welfare needs are difficult to meet in laboratory settings. Progress through replacement with alternatives, refinement of housing conditions, and reduction of numbers is genuine but insufficient. Continued advocacy for 3Rs progress in primate research is a high-impact welfare priority.

What You Can Do

Support organisations advocating for replacement of primate research with alternatives
Follow NC3Rs and FRAME for progress on primate research alternatives
Engage with the ethical debate about primate research use in public discourse
