Modern animal testing for biomedical and disease research first gained prominence in the 1880’s and 1890’s. Since then, there has been a large amount of controversy over the use of animal testing for biomedical research purposes, especially for chronic diseases and cancer. Many are worried about the efficiency and effectiveness of the research, and whether animal testing is still necessary in today’s world, where many other, less expensive, more effective alternatives exist. Animal experimentation, to treat or research chronic diseases and cancer, is detrimental to society because of the biological differences between humans and animals, the expense, and the existence of more precise alternatives. It is no secret that the animals …show more content…
It is because of differences that animals cannot be successfully used for research, despite the fact that we, as a society, often use them as test subjects. For example. In 2006, a drug called TGN1412, intended to treat B cell chronic lymphocytic leukemia and rheumatoid arthritis, was tested on non-human primates in preclinical trials. The researchers in charge of the project reported no adverse side effects and soon the drug passed tests and was allowed to be tested on humans. Within minutes of the first dose, the patients developed life threatening reactions, and even went into multi-organ failure (Attarwala 2010). This is a prime example of the biological differences between humans and animals, as even though the drug was tested and found to be successful in animals similar to humans, the drug, when actually tested on humans, proved to be incredibly dangerous. Another example of the effect on biological differences on research is between chimpanzees and humans infected with AIDS, which is now
