WORLD CONGRESS About the series

The World Congress on Alternatives and Animal Use in the Life Sciences is a significant international event that focuses on advancing the field of alternatives to animal testing in research and education. The congress provides a platform for scientists, researchers, policymakers, and other stakeholders to exchange knowledge, share best practices, and discuss the latest developments in the field.

These congresses typically cover a wide range of topics related to alternatives to animal use, including the development and validation of alternative methods, ethical considerations, regulatory aspects, and the implementation of alternative approaches in various scientific disciplines such as toxicology, biomedical research, and education.

The World Congress on Alternatives is held periodically, with each congress aiming to bring together experts from around the world to collaborate and accelerate progress towards reducing, refining, and replacing the use of animals in scientific research and testing. These events play a crucial role in shaping the future direction of research and policy in this area, ultimately contributing to the promotion of more humane and scientifically sound approaches to advancing the life sciences.
