In certain research investigations, cell, tissue, organ cultures, and computer models can be used at least in the preliminary phases of the investigation. Some examples of where animals are necessary in research include the development of a vaccine against HIV and improvement of methods to relieve mental stress and anxiety. These challenges can only be addressed by research with animals. Computer models and cultures cannot get the whole body effect of an experiment. Humans are the only alternatives to animals for this and when faced with this alternative, most people prefer the use on animals as the research model.
Animal research is necessary to maintain our society's well being.
Animal Research is necessary to continued progress in human health. If other methods were available they would be given a fair chance but for now only animal experimentation works best. If all of the advances in human health were taken away our society would still be in a primitive age.
