The National Anti-Vivisection Society in UK, founded in 1875, is the world’s first body to challenge the use of animals in research and continues to lead the campaign today. NAVS has spearheaded the adoption of advanced, non-animal methods; exposed laboratory animal suffering and breaches of regulations with our undercover investigations; funded non-animal scientific and medical research; educated public and media about the flaws of animal research and provided legislators detailed briefings to support the replacement of animals in research with advanced methods.
Millions of animals suffer and die in cruel, unscientific, and futile experiments – yet there are sophisticated non-animal methods available. Our objectives are to awaken the conscience of humanity in all parts of the world to the iniquity of procedures causing suffering or distress to living creatures and the breeding and supply of animals for such purposes; to persuade regulators and legislators to adopt non-animal methods and end the use of animals in research.
