Primates in Research - 3Rs Progress and Gaps

Progress and remaining gaps in applying the 3Rs (Replace, Reduce, Refine) to primate use in biomedical research.

Key Facts

Non-human primate use in UK research has declined from over 5,000 in 1995 to under 3,000 annually currently
Organoids and advanced in vitro models are increasingly replacing some primate procedures in pharmacology
Housing and social needs of primates remain inadequately met in some laboratory settings despite progress
Pain and distress scoring protocols for macaques and marmosets are now validated and widely used
International coordination on primate research reduction is limited by regulatory differences between countries
