Does animal testing help humanmedicine?33 facts to consider.1) Less than 2% of human illnesses (1.16%) are ever seen inanimals. Over 98% never affect animals.2) According to the former scientific executive of HuntingdonLife Sciences, animal tests and human results agree"5%-25% of thetime."3) Among the hundreds of techniques available instead of animalexperiments, cell culture toxicology methods give accuracy rates of 80-85%4) 92% of drugs passed by animal tests immediately fail when first triedon humans because they’re useless, dangerous or both.5) The two most common illnesses in the Western world are lung cancerfrom smoking and heart disease. Neither can be reproduced in labanimals.6) A 2004 survey of doctors in the UK showed that 83% wanted aindependent scientific evaluation of whether animal experiments hadrelevance to human patients. Less than 1 in 4 (21%) had moreconfidence in animal tests than in non-animal methods.7) Rats are 37% effective in identifying what causes cancer to humans –less use than guessing. The experimenters said:“we would have beenbetter off to have tossed a coin."8) Rodents are the animals almost always used in cancer research. Theynever get carcinomas, the human form of cancer, which affectsmembranes (eg lung cancer). Their sarcomas affect bone and connectivetissue: the two arecompletely different.9) The results from animal tests are routinely altered radically by diet,light, noise, temperature, lab staff and bedding. Bedding differencescaused cancer rates of over 90% and almost zero in the same strain ofmice at different labs.10)Sex differences among lab animals can cause contradictory results.This does not correspond with humans.
11) 75% of side effects identified in animals never occur.12) Over half of side effects cannot be detected in lab animals.13) Vioxx was shown to protect the heart of mice, dogs, monkeys andother lab animals. It was linked to heart attacks and strokes in up to139,000 humans.14) Genetically modified animals are not like humans. The mdx mouse issupposed to have muscular dystrophy, but the muscles regenerate withno treatment.15) GM animal the CF- mouse never gets fluid infections in the lungs –the cause of death for 95% of human cystic fibrosis patients.16) In America, 106,000 deaths a year are attributed to reactions tomedical drugs.17) Each year 2.1 million Americans are hospitalised by medicaltreatment.18) In the UK an estimated 70,000 people are killed or severely disabledevery year by unexpected reactions to drugs. All these drugs havepassed animal tests.19) In the UKs House Of Lords questions have been asked regarding whyunexpected reactions to drugs (which passed animal tests) kill morepeople than cancer.20) A German doctors congress concluded that 6% of fatal illnesses and25% of organic illness are caused by medicines. All have been animaltested.21) According to a thorough study, 88% of stillbirths are caused by drugswhich passed animal tests.22) 61% of birth defects were found to have the same cause.23) 70% of drugs which cause human birth defects are safe in pregnantmonkeys.24) 78% of foetus-damaging chemicals can be detected by one non-animal test.25) Thousands of safe products cause birth defects in lab animals –including water, several vitamins, vegetable oils, oxygen and drinkingwaters. Of more than 1000 substances dangerous in lab animals, over97% are safe in humans.
26) One of the most common lifesaving operation (for ectopicpregnancies) was delayed 40 years by vivisection.27) The great Dr Hadwen noted "had animal experiments been reliedupon...humanity would have been robbed of this great blessing ofanaesthesia."28) Aspirin fails animal tests, as do digitalis (heart drug), cancer drugs,insulin (which causes animal birth defects), penicillin and other safemedicines. They would be banned if vivisection were believed.29) Blood transfusions were delayed 200 years by animal studies.30) The polio vaccine was delayed 40 years by monkey tests.31) 30 HIV vaccines, 33 spinal cord damage drugs, and over 700treatments for stroke have been developed in animals. None work inhumans.32) Despite many Nobel prizes going to vivisectors, only 45% agree thatanimal experiments are crucial.33) The Director of Research Defence Society, (which serves only todefend vivisection) was asked if medical progress could have beenachieved without animal use. His written reply was "I am sure it couldbe."See 50 disasters of animal testing here.References1) Page, Dr T, "Vivisection Unveiled", John Carpenter, 1997, p62) Animal Toxicity Studies:Their relevance to man Lumley & Walker (ed) pp57-67, Quay, 19893) Clemedson C, McFarlane-Abdulla E, Andersson M, et al.
