Animal experiments are so worthless that up to half of them are never even published.

How do we benefit from animal testing?

Animal research has helped us to make life-changing discoveries, from new vaccines and medicines to transplant procedures, anaesthetics and blood transfusions. millions of lives have been saved or improved as a result. Animal research has been important in the development of many major medical advances.

How are drugs tested on humans?

Done at hospitals and research centers around the country, clinical trials are conducted in phases. Phase 1 trials try to determine dosing, document how a drug is metabolized and excreted, and identify acute side effects. Usually, a small number of healthy volunteers (between 20 and 80) are used in Phase 1 trials.

What animals are used for drug testing?
