1) Less than 2% of human illnesses (1.16%) are ever seen in animals. Over 98% never affect animals.
2) According to the former scientific executive of Huntingdon Life Sciences, animal tests and human results agree “5%-25% of the time.”
3) Among the hundreds of techniques available instead of animal experiments, cell culture toxicology methods give accuracy rates of 80-85%
4) 92% of drugs passed by animal tests immediately fail when first tried on humans because they’re useless, dangerous or both.
5) The two most common illnesses in the Western world are lung cancer from smoking and heart disease. Neither can be reproduced in lab animals.
6) A 2004 survey of doctors in the UK showed that 83% wanted a independent scientific evaluation of whether animal experiments had relevance to human patients. Less than 1 in 4 (21%) had more confidence 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 been better off to have tossed a coin.”
8) Rodents are the animals almost always used in cancer research. They never get carcinomas, the human form of cancer, which affects membranes (eg lung cancer). Their sarcomas affect bone and connective tissue: the two are completely different.
9) The results from animal tests are routinely altered radically by diet, light, noise, temperature, lab staff and bedding. Bedding differences caused cancer rates of over 90% and almost zero in the same strain of mice 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 and other lab animals. It was linked to heart attacks and strokes in up to 139,000 humans.
14) Genetically modified animals are not like humans. The mdx mouse is supposed to have muscular dystrophy, but the muscles regenerate with no 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 to medical drugs.
17) Each year 2.1 million Americans are hospitalised by medical treatment.
18) In the UK an estimated 70,000 people are killed or severely disabled every year by unexpected reactions to drugs. All these drugs have passed animal tests.
19) In the UKs House Of Lords questions have been asked regarding why unexpected reactions to drugs (which passed animal tests) kill more people than cancer.
20) A German doctors’ congress concluded that 6% of fatal illnesses and 25% of organic illness are caused by medicines. All have been animal tested.
21) According to a thorough study, 88% of stillbirths are caused by drugs which 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 pregnant monkeys.
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 drinking waters. Of more than 1000 substances dangerous in lab animals, over 97% are safe in humans.
26) One of the most common lifesaving operation (for ectopic pregnancies) was delayed 40 years by vivisection.
27) The great Dr Hadwen noted “had animal experiments been relied upon…humanity would have been robbed of this great blessing of anaesthesia.”
28) Aspirin fails animal tests, as do digitalis (heart drug), cancer drugs, insulin (which causes animal birth defects), penicillin and other safe medicines. 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 700 treatments for stroke have been developed in animals. None work in humans.
32) Despite many Nobel prizes going to vivisectors, only 45% agree that animal experiments are crucial.
33) The Director of Research Defence Society, (which serves only to defend vivisection) was asked if medical progress could have been achieved without animal use. His written reply was “I am sure it could be.”

Hey @Caduceuse, Keep in mind that dogs differ from humans biologically in many ways. Even if an experiment on a dog is “successful,” that does not, by any stretch of the imagination, mean that the same experiment, when performed on humans, will also be successful.
92% of the drugs that pass with flying colors when tested on animals fail when they reach human clinical trials. So, before you praise animal testing simply because dogs can “react,” remember that we are not dogs. Therefore, studies in dogs don’t mean a whole a lot when translated to studies in humans.
Also, to say that a dog’s life doesn’t hold value simply because dogs don’t live as long as humans is speciesism at its finest. By this logic, do you also not value the life of a human who dies before they’re fifteen-years-old?
I can tell you with complete certainly that although you may not value a dog’s life, dogs do value them. They don’t want to burned, shocked, poisoned, isolated, starved, forcibly restrained, addicted to drugs, and/or brain-damaged in labs. I mean, who would?
I hope this info helps clear up any confusion you have! If you have any other questions about this, feel free to e-mail us at [email protected]. 🙂
@Caduceuse – First off, I never claimed not to take medication. I am fully aware that the medication I take was tested on animals. Many of us have had long discussions on the topic – And while many of us do have to take medication to survive, none of us advocate animal testing. I’m pretty sure most of us would gladly let them test the medications on us, if we had that option.
Animal testing is ineffective, and abusive. What you claim would be HELPING those dogs? In most cases, they don’t get the formula quite right on the first try. So the first few attempts at testing either make the animal sick, or kill them. On top of that, they usually give them mega-doses of the medication to test the over-dose point (which wouldn’t be the same in animals and humans ANYWAY).
@Rachel-S no offense towards your judgement of my statement, but I do not believe I was being disrespectful, especially not when you take into consideration the extent of some of Peta’s campaigns. I simply made that suggestion to offer a different viewpoint on animal testing. It was obviously ineffective.
