Frequently Asked Questions

Examples include: the development of anaesthesia; bacteriology; germ theory; the stethoscope; morphine; radium; artificial respiration; antiseptics; the CAT, MRI, and PET scans; the discovery of the relationships between cholesterol and heart disease and between smoking and cancer; the development of x-rays; and the isolation of the virus that causes AIDS.

Animal testing played no role in these and many other similar developments. Clinical trials, the use of human volunteers, case studies, autopsy reports and statistical analyses permit far more accurate observation – as well as the use of actual environmental factors related to human disease.

Basic research can be conducted using non sentient animals, on a computer, in a physics or chemistry lab, doing thought experiments, or in myriad other ways. Virtually all basic research in chemistry and physics (that led to the discoveries listed above) does not involve using sentient animals and many of the greatest discoveries that reduced the burdens of illness and disability came from these two fields.

The fact that animals were used does not necessarily mean that they were part of the scientific process that led to a medical discovery. In some cases, animal research has simply served to verify findings made from non-animal research and its contribution has been overstated.

Non-animal models may lack the integration and longevity of an intact organism. They are designed to stimulate human biology up to a certain level or organization and complexity. However, despite the current limitations, they are superior to the inaccurate animal model. A whole living rat does not represent a whole living human.

The alternatives to animal testing are primarily based on biochemical assays, experiments in cells that are carried out in- vitro, and computational models and algorithms. These techniques are typically far more sophisticated and specific than traditional approaches to testing in whole animals, and many in vitro tests are capable of producing information about the biological effects of a test compound that are equally accurate and in some cases more accurate than the information collected from studies in whole animals*.

Drugs have been developed in spite of animal research and not necessarily because of animal research; it may just so happen that there is the same outcome in a particular species (or even particular age or strain or gestational status) to which the results can be extrapolated similarly by chance.  The same findings could have been found through alternative methods and in fact animal research may have delayed the discovery of cures through abandoned treatments found to be ineffective in animals.

HRA is not suggesting that medical associations and associated bodies do not have a genuine interest in curing diseases. However, perspectives on how this can be achieved are influenced by many factors; vested interests, support of the status quo, money (grant income for universities and institutions), career dependency and status are just some. Responsible parties don’t want to admit that have been sustaining an ineffective model (how can they explain that to the public who are donors, patients and tax payers?) and there are challenges with learning new research methods, changing engrained practice, the time taken to validate alternatives, technical issues in comparing results and pressure from peers not to speak out (see the videos Test Subjects and interview with Dr Ray Greek for more).

Research is approved by peer review not systematic reviews or meta-analysis which would result in greater scrutiny of research projects.

It should also be noted that many scientists and medical professionals do not support medical research and there are organisations comprised of medical professionals opposing animal research on scientific grounds, such as Physicians Committee for Responsible Medicine , Safer Medicines Trust and the Medical Research Modernization Committee, who agree that experiments on animals do not lead to cures for human disease.

Whilst the species difference is removed, HRA proposes that in-vitro models also be used for veterinary research and education (for example, there are models that can be used for surgical training, or ethically sourced cadavers or supervised surgeries) and organs-on-a-chip can be used with animal cells to test veterinary applications.

 Only in the case of trailing treatments in ill animals for which there is no current cure would HRA accept the use of animals suffering from the said condition as veterinary research.

Some veterinary research is focussed on increasing the productivity of animals rather than for the health and well-being of animals, to which HRA objects.

Immoral and illegal to use humans without their consent – as per the Helsinki Declaration and Nuremberg Code. Aside from the ethical argument, there are scientific factors.  Stressed people (like stressed animals) who are otherwise physically healthy do not respond to medication in the same way as real patients (i.e. people with existing disease). People in jail are not representative of the general population and no substitute for a personalised approach to medicine.

This is a moral issue which society needs to consider and on which HRA has no firm position.

However, recently, scientists discovered that a mature fully specialised cell, for example a human skin cell, in the right conditions could be induced to mimic the characteristics of an embryonic stem cell. These are known as induced pluripotent stem cells (iPS cells)*. HRA believes iPS cells have the potential to replace animals in some research.

Non-animal methods are rarely used in isolation for biomedical research, in part due to regulatory requirements, so it is difficult to attribute a cure to non-animal research. You must still test your product on a rodent and a non- rodent species in order to proceed to clinical trials and subsequent marketing approval.

However, in terms of research outcomes, progress in understanding AIDS has come from clinical, epidemiological, and in vitro studies.

Some significant findings from in vitro testing include cancer screening treatments, testing drugs with biochips, and replicating human skin for research. In vitro models of the brain and the blood-brain barrier are being used for studies of neurotransmitter pathways, electrophysiological characteristics, morphological associations of human diseases (i.e., Alzheimer’s, Parkinson’s, Huntington’s, and epilepsy), new drug designs, receptor targets, and modes of action of new pharmaceuticals.

Basic research is held to a lower standard than clinical research and is often to satisfy scientific curiosity and develop hypothesis that are in reality only relevant to animals and simply lead to more research and more publications. Clinical relevance is poor. For example, one study found that fewer than 10% of highly promising basic science discoveries enter routine clinical use within 20 years.

Finding new facts does not mean advancing human health.

Regardless of the species and the classification we afford them, subjecting animals to research is unethical and unscientific. It is unacceptable to justify their use in research by comparison with other inhumane treatments of that species outside of the laboratory context. The collective evidence is now robust enough that biologists and veterinarians increasingly accept fish pain as a reality*. Whilst fish may not evoke the same empathy that a cat or dog would, they have a right to be protected from harm.

There is no legal requirement for animal experimentation in basic and applied research, nor for it to be part of education and training. However, Government regulators require that new consumer products, medicines,and industrial and agricultural chemicals are tested to identify potential dangers to human and animal health, as well as to the environment. For some product types (drugs and vaccines, biologicals), animal testing includes testing for efficacy as well as safety (toxicity). Before a drug can be marketed in Australia, it must be evaluated by the Therapeutic Goods Administration (TGA). Currently, one of the stages in the evaluation process is to evaluate animal pharmacology and toxicology data.
