The California Biomedical Research Association claims that nearly every medical breakthrough in the last 100 years has resulted directly from research using animals (“Why Are Animals Necessary in Biomedical Research,” 2013). However, 95% of drugs fail in human trials despite promising results in animal tests ("Arguments against animal testing,” n.d). Also, Dr. Richard Klausner, former director of the US National Cancer Institute states that they have cured cancer for decades and it simply didn’t work in human beings, proving that animal testing isn’t as effective as people may …show more content…
Studies have shown that 95% of experimental drugs that are safe and effective on humans fail in human clinical trials because they are too dangerous word don 't work (“11 Facts About Animal Testing,” n.d). The animal tests don 't make sure the buyers are safe; companies kill animals not to protect us but to protect themselves in case one of their products blinds of poisons you (“The Life Of A Test Animal," n.d). Animal tested drugs have killed, disabled, or harmed millions of people (“Stop animal testing,” 2006). Diseases that are artificially used in animals in a laboratory are never identical to those that naturally happen to humans; animal species differ from one another a biologically, so it becomes more unlikely that the animal experiment results will correctly solve certain human conditions (“Experiments on Animals: Overview,” n.d). For example, former National Cancer Institute director, Dr. Richard Klausher said that they have cured mice with cancer for decades but it did not work on humans (“Experiments on Animals: Overview,” n.d). Adult stem research is more effective than animal testing because there are no complications or failure related to tissue rejection; in fact, International researchers using adult skin cells, cells that are in all growing human tissue, have shown some success in treating Cardiac Infraction , Crohn’s disease, and Thalassemia (“Stop animal testing,” 2006).
