The document discusses systematic reviews in research using animals from a policy perspective. It provides data on the number of animal experiments conducted annually in the Netherlands from 1978 to 2010. It also presents examples of alternative methods that have replaced animal models for vaccine potency testing at RIVM/NVI, reducing animal use. Finally, it outlines elements of the Netherlands' national action plan to promote alternative methods and the 3Rs (replace, reduce, refine) in animal research through initiatives like knowledge sharing, collaboration, education, and funding incentives.
