THE EVIDENCE
Why Animal Testing Fails Humans
Poor Predictability
The NIH reports that 95% of drugs safe and effective in animals fail in human clinical trials. Only 5% of animal-tested therapies gain human approval.
Species Biology Differs
Rodents have fundamentally different immune systems, metabolic processes and disease mechanisms to humans — making results species-specific, not universal.
Human Genetic Diversity Ignored
Animal models cannot represent the genetic variation in human populations affecting treatment responses, metabolism and disease vulnerability.
Ethically Indefensible
With validated, accurate human-relevant alternatives available, the continued use of animals for research is both scientifically unjustifiable and ethically wrong.
