An article by Dr Ray Greek explaining how animal use is damaging progress in medical research.

The paper presented by American medical professionals in favour of reliable technology instead of animal use.

"A review of 20 years’ use of genetically altered animals to study heart disease was published in ALTEX.  It notes that there has been no published research showing a new approach emerging from this area, which has been very popular.  Instead, criticism has been rife, arguing that it is misleading and likely to prevent progress in identifying genes involved in heart disease. It concludes that ‘although these approaches are without exception deemed "very promising" in the literature, it cannot be expected that research on GMO will make any contribution to a new therapeutic strategy in the near future.’"
ALTEX. (2009;26(1):41-51)

"Immunologists need to stop using mice and use technology to study illnesses, writes Stanford immunologist Mark Davis. 
"We seem to be in a state of denial, where there is so much invested in the mouse model that it seems almost unthinkable to look elsewhere...Mice are lousy models for clinical studies".

He foresees routine high-throughput assays that could quickly and cheaply compare hundreds of differences between people of varying levels of health."
Stanford University News Jan 7 2009.

“The reason we use animal tests is because we have a comfort level with the process . . . not because it is the correct process, not because it gives us any real new information we need to make decisions.”

Melvin E. Andersen, director, computational systems biology, Hamner Institutes for Health Sciences, USA (quoted by Gaul, Washington Post, Saturday, April 12, 2008; Page A01).

"Despite claims by the research industry, chimpanzees have proven to be a poor model for human cancer research" states a recent study. Chimpanzee tumours are extremely rare and biologically different from human cancers.

The study concludes: "It would be unscientific to claim that chimpanzees are vital to cancer research and reasonable to conclude that cancer research would not suffer if the use of chimpanzees were prohibited..."
ATLA 37, 399-41

“The predictive value of the non-human SHIV-challenge model [primate model of AIDS] is not supported by this experience.”
British Medical Journal 19 November 2008, doi:10.1136/bmj.a2571

“... the only scientific analyses made to date have been critiques that have revealed nonhuman primate models to be of little relevance to human medicine.”
Nature Medicine 14, 1011-1012 (1 October 2008)

A research group headed by Professor Ian Roberts, of the London School of Hygiene and Tropical Medicine has called for an end to animal experiments following an investigation.  Their findings, published in the British Medical Journal (28th Feb 2004), show that experiments are not justified and can’t be applied to humans.

"The reason why I am against animal research is because it doesn't work, it has no scientific value and every good scientist knows that."
Dr. Robert Mendelsohn, M.D., 1986, Head of the Licensing Board for the State of Illinois.

"Results from animal tests are not transferable between species, and therefore cannot guarantee product safety for humans...
In reality these tests do not provide protection for consumers from unsafe products, but rather they are used to protect corporations from legal liability."

Herbert Gundersheimer, M.D., Baltimore, Maryland, 1988.

"Animal experimentation is fallacious, useless, expensive, and furthermore, cruel."
G. Tamino, Congressman and researcher at the University of Padua, Italy.

"Vivisection is barbaric, useless, and a hindrance to scientific progress. …There are, in fact, only two categories of doctors and scientists who are not opposed to vivisection: those who don't know enough about it, and those who make money from it."
Dr. Werner Hartinger, 1988/89, surgeon of thirty years, West Germany

"I agree that for the benefit of medical science, vivisection has to be stopped. There are lots of reasons: the most important is that it is simply misleading, and both the past and present testify to that."
Professor Salvatore Rocca Rossetti, surgeon and professor of urology at the University of Turin, cit. Ray and Jean Greek, Specious Science (New York/London: Continuum, 2002), p.169.

"The assumption that an animal species can stand as a reliable model for human biological reactions amounts to playing Russian Roulette with the patient's life."
Dr Claude Reiss, DLRM Newsletter, No.9, Autumn 2002.

"It is impossible to evaluate the safety of using animal studies to predict the safety of drugs and chemicals in man."
D. V. Parke, Emeritus Professor of Biochemistry, University of Surrey, 1 May 1996.

"My own conviction is that the study of human physiology by way of experimenting on animals is the most grotesque and fantastic error ever committed in the whole range of human intellectual activity."
Dr. G. F. Walker, 1933.

"Why am I against vivisection? The most important reason is because it's bad science, producing a lot of misleading and confusing data which pose hazards to human health."

Dr. Roy Kupsinel, M.D., 1988, medical magazine editor, USA.

"Conclusions drawn from animal research, when applied to human beings, are likely to delay progress, mislead, and do harm to the patient. Vivisection, or animal experimentation, should be abolished."
Dr. Moneim Fadali, M.D., 1987, F.A.C.S., Diplomat American Board of Surgery and American Board of Thoracic Surgery, UCLA faculty, Royal College of Surgeons of Cardiology, Canada.

"Not one single animal experiment has ever succeeded in prolonging or improving, let alone saving, the life of even one single person."

Paper published by Dr. med. Heide Evers, D-7800 Freiburg, 1982.

“What good does it do you to test something in a monkey?  You find five or six years from now that it works in the monkey, and then you test it in humans and you realize that humans behave differently from monkeys, so you’ve wasted five years”

Dr Mark Feinberg, leading AIDS researcher.

"The lack of correlation between toxicity data in animals and adverse effects in humans is well known."

A. Gorman, et al., Comparative Endocrinology (New York, John Wiley and Sons, 1983), p.33

"Nobody has become a surgeon because of having operated on animals. He has only learnt wrongly through animals.”
Professor Salvatore Rocca Rossetti, surgeon and professor of urology at the University of Turin, cit. Ray and Jean Greek, Specious Science (New York/London: Continuum, 2002) p.169

"What is the value of routine tests in animals for prediction of chemical teratogens? The correlation between known effects in laboratory animals and clinical adverse effects in very low".
Dr. A. P. Fland, Journal of the Royal Society of Medicine, vol.71, 1978, pp.693-6

"Some findings in colon cancer mice, which were very good models, actually led to clinical trials in humans which resulted in an increase in cancer."
Dr. Bjorn Ekwall, Chairman of the Cytotoxicology Laboratory, Toxicolog In vitro, Aug-Oct 1999

"The extensive animal reproductive studies to which all new drugs are now subjected are more in the nature of a public relations exercise than a serious contribution to drug safety."
Dr. J. E. Green of the National Cancer Institute Laboratory, Journal of the National Cancer Institute, 2001, 93:976

"For the great majority of disease entities, the animal models either do not exist or are really very poor. The chance is of overlooking useful drugs because they do not give a response to the animal models commonly used."

Dr. C. Dollery, in Risk-Benefit Analysis in Drug Research, p.87

"The probability of experimental results in animals and in man coinciding is so slight that it is comparable to a game of chance. Nonetheless on this improbable game of roulette we bet millions of dollars each year."
Professor Herbert Hensel, physiologist at the University of Marburg. Cit., W. Hartinger, Gentenchnollgie, September, 1995

"Prediction of human lethal and toxic doses is poor due to species differences between animals and humans, and the toxic mechanisms of the chemicals cannot be directly predicted using current animal tests."

Dr. Bjorn Ekwall, Chairman of the Cytotoxicology Laboratory, Toxicolog In vitro, Aug-Oct 1999

"Experiments with animals have yielded considerable information concerning the teratogenic effects of drugs. Unfortunately, these experimental findings cannot be extrapolated from species to species, or even from strain to strain within the same species, much less from animals to humans."

Dr. S. J. Yaffe, American College of Laboratory Animal Medicine, 1980, p.13.

"Like every member of my profession, I was brought up in the belief that almost every important fact in physiology had been obtained by vivisection and that many of our most valued means of saving life and diminishing suffering had resulted from experiments on the lower animals.
I now know that nothing of the sort is true concerning the art of surgery: and not only do I not believe that vivisection has helped the surgeon one bit, but I know that it has often led him astray."
Prof. Lawson Tait, M.D., 1899, Fellow of the Royal College of Surgeons (F.R.C.S.), Edinburgh and England.

"There is a natural law connected with metabolism, according to which a biochemical reaction that has been established for one species is valid only for that particular species and no other...Animal experimentation is fallacious, useless, expensive, and furthermore, cruel."
G. Tamino, Congressman and researcher at the University of Padua, Italy.

"[Vivisection] is not science - it is a lottery. However, we are not playing games. At stake are health and life. There is absolutely no connection between vivisection and human health. The day it was decided to develop medicines using animals, it was a sad day for mankind."

Dr A. Brecher, M.D.

"After 41 years' experience as a surgeon, I can say with certainty that in my case animal experiments have contributed nothing to extending my surgical knowledge. That is

Dr J. Lefanu, Sunday Telegraph, 23 November 1997.

"A drug that is tested on animals will have completely different effects in man. There are uncounted examples that could be cited - a single Amanita Phalloides mushroom can wipe out a whole human family, but is a healthfood for the rabbit, one of the favorite laboratory animals..."

Dr. med. Karlheinz Blank, West Germany, in Der Tierschutz, Nr. 62, 1985, Journal of the Arbeitsgemeinschaft Deutscher Tierschutz.

"Among experienced public health officials, it is well-known that you can 'prove' anything with animal studies. This is because there are so many different animal model systems and each system gives different results."

Dr. Irwin D. Bross, former Director of Biostatistics at Roswell Park Memorial Institue (The AV, November 1
