Animal Research – Why?

Animal research has contributed to most of the medical advances we now take for granted. We have probably all benefited from vaccines and antibiotics to prevent and treat infections, and anesthetics used in all forms of surgery. Medicines and treatments can now overcome serious conditions such as diabetes, asthma, and high blood pressure and effectively treat life threatening illnesses such as Cancer, Heart disease and HIV to name but a few.

Medical research has saved and improved the lives of millions of people. Animals have benefited too through the extensive development of veterinary medicines and procedures. Today’s medicines and surgical techniques could not have been discovered without an in depth understanding of disease and the way the human body and those of a variety of animal species works. All of which is the result of basic research programmes in universities, hospitals and research institutes across the world. These insights can then be taken forward by pharmaceutical companies to develop new medicines which doctors and vets use to treat their patients.

Our client Cambridge University explains the vital use of animals in their own Cancer research studies.

A short clip explaining why animals are essential in medical research and drug discovery.


Medical and scientific organisations and leading scientists all agree that animal research is essential for medical progress.

“Scientific and medical research is a drawn-out process and the contribution of animal research is frequently overlooked by the time successful therapy reaches patients. We live longer and healthier lives than ever before. Whilst there have been remarkable improvements in the human environment, animal research has played a major part in developing improvements in human health. Animal research advanced the treatment of infections, helped with immunisation, improved cancer treatment and has had a major impact on managing heart disease, brain disorders, arthritis and transplantation.”

– Professor Robert Winston

Timeline of the world’s medical advances

Pre 20th century breakthroughs in medical research:

Animal research model used: birds

At the end of the 19th century, malaria was believed to be contracted through inhalation of dirty water. Several biologists, Manson, Koch, King and Lavern, separately developed the theory that malaria may be caused by mosquito bites.

Anthrax is an infectious disease due to a type of bacteria called Bacillus anthracis. Infection in humans most often involves the skin, gastrointestinal tract, or lungs.

Animal research model used: rabbits, dogs

Rabies is a very serious viral infection that targets the brain and nervous system. It is spread by animals to humans. Once the symptoms of rabies have developed, the condition is almost always fatal.

Animal research model used: mice, rats

Experiments on cholera immuno-serum in guinea-pigs showed that unlike previous sera, it did not affect bacterial toxins, but provided immunity by preventing the bacteria from moving and growing. This was termed bacteriolytic immunity. As with anti-toxic immunity, animals could gain immunity through injection with the blood of an immunised animal.

Animal research model used: chickens

In 1912 Gowland Hopkins showed that beriberi could be caused by lack of nutrients in the diet. He investigated the nutritional needs of rats and mice, feeding young rats on casein, lard, sucrose, starch and minerals. Half the group also received 2ml of milk daily. Those receiving the milk grew well.

Typhoid, sometimes known as enteric fever, is a disease caused by the bacterium Salmonella enterica serovar Typhi. Classic typhoid fever is a serious disease. It can be life-threatening unless treated promptly with antibiotics. The disease lasts several weeks and convalescence takes some time.

Without Scientific research all our lives would be far worse off. Mankind has developed treatments, cures, medicines and surgical procedures that have increased our life expectancy beyond any other method. Based on the breakthroughs shown above in only a short 100 years who knows where we will be in the next 100 years, a cure or vaccine for all Cancers? Dementia? AID’s?

With such a deep understanding of human and animal biology and continued investment in research it is entirely possible.

    "Animal research is essential for all our futures. thanks to such research, we have better lives and the survival rates for many cancers, for instance, continue to improve."

    - Professor Fran Balkwill, QMUL
    "The use of animals in research has enabled major advances in the understanding of biology and led to the development of nearly every type of drug, treatment or surgical procedure in contemporary medical and veterinary practice."

    - Wellcome Trust
    "Animal research and testing has played a part in almost every medical breakthrough of the last century. It has saved hundreds of millions of lives worldwide..."

    - Joan Ryan, Former UK Home Office minister
    "Without animal research, polio would still be claiming thousands of lives each year."

    - Albert Sabin, developer of the Polio vaccine
  • Our position statement on the use of Animals in Medical research

    S3 Science Recruitment works alongside the majority of organisations within the research community. Naturally we fully support their valuable and life-saving work. We understand that the use of laboratory animals enables scientific breakthroughs and continued progress in medical developments.

    We always take the time to explain to our candidates that the use of laboratory animals goes hand in hand with providing the highest level of welfare and care. We also fully support the Reduction, Refinement and Replacement of the use of animals in research and look forward to the day a viable alternative becomes available. In the meantime we will continue to attract animal loving candidates who care passionately about animal care and welfare.
