Medical research using animals is scientifically flawed. The physiological differences between animals and humans are so great that it is not possible to accurately apply data gained from laboratory animals to people. Drugs tested on animals are often not applicable or safe for humans, as evidenced by drugs like Eraldin and Opren, which were safety tested and approved on animals but went on to cause serious illness and death in patients. Most human diseases are uniquely human. To develop the safest, most effective treatments requires the study of human cells, tissues and organs. Humane alternatives, without experimenting on animals are possible and get results. The Dr Hadwen Trust has been helping pioneer new medical techniques and treatments for 37 years, without using vivisection.
