Implementing the 3Rs - Replace, Reduce, Refine - in non-human primate research requires sustained institutional commitment and innovative scientific approaches.
Non-human primates used in research face significant welfare challenges including social isolation, invasive procedures, and psychological stress from captivity. Full implementation of the 3Rs - particularly replacement - is the ultimate welfare goal. Until replacement is achievable for all research purposes, rigorous implementation of refinement and reduction are ethical obligations.
