Definition: The antivivisectionist's purpose is to prevent or stop biological research, emphasizing non-human subjects. Definition: Antivivisectionism is a term used by anti-vaccination advocates in reference to any form of experimental testing or biological research that could potentially lead to the development of non-human primate viruses. It involves individuals who believe that animals and plants are not immune and therefore should not be tested for vaccines, biotinization, or other therapeutic agents. In this context, the antivivisectionist's goal is to deny the safety of experimental treatments and push back against any form of non-human animal testing. The term also suggests a stance that goes beyond mere opposition to vaccine development, advocating for an ethical approach to human health research.
