Dear Editor,The April 2014 issue of Theoretical Medicine and Bioethics [1] presented eight essays regarding the use of nonhuman animals in biomedical research. While I appreciate the essays concerning contemporary research—which were well written and offered new thinking from the fields of ethics and ethology—I believe the journal, via the topics and the authors chosen, failed to communicate the most important fact regarding the current science pertinent to the use of nonhuman animals in research.The foundational reason for using chimpanzees and (...) other animals in research is their predictive value for human response to drugs and disease. This was alluded to by several of the authors when they discussed the necessity of using nonhuman animals. For example, Smith writes: “A common assumption in the selection of nonhuman animal subjects for research and the approval of research is that, if the risks of a procedure are too great for humans, and if there is a so-called scientific necessity, ..

The ethics of using nonhuman animals in biomedical research is usually seen as a subfield of animal ethics. In recent years, however, the ethics of animal research has increasingly become a subfield within research ethics under the term “animal research ethics”. Consequently, ethical issues have become prominent that are familiar in the context of human research ethics, such as autonomy or self-determination, harms and benefits, justice, and vulnerability. After a brief overview of the development of the field and a discussion (...) of relevant theoretical ethical frameworks, I consider two of these issues, namely autonomy and self-determination on the one hand, and harms and benefits on the other hand. My concern is with philosophical and ethical issues, rather than animal research oversight. I focus my discussion on nonhuman primates, as the most plausible nonhuman candidates for this approach. I conclude that the approach, although promising, depends strongly on the moral status of nonhuman research subjects. (shrink)

One of the most controversial areas of animal research is the use of nonhuman primates for fundamental research. At the centre of the controversy is the question of whether the benefits of research outweigh the harms. We argue that the evaluation of harms and benefits is highly problematic. We describe some common procedures in neurological research using nonhuman primates and the difficulties in evaluating the harm involved. Even if the harm could be quantified, it is unlikely that it could be (...) meaningfully aggregated over different procedures, let alone different animals. A similar problem arises for evaluating benefits. It is not clear how benefits could be quantified, and even if they could be, values for different aspects of expected benefits cannot be simply added up. Sorting harms and benefits in three or four categories cannot avoid the charge of arbitrariness and runs the risk of imposing its structure on the moral decision. The metaphor of weighing or balancing harms and benefits is inappropriate for the moral decision about whether to use nonhuman primates for research. Arguing that the harms and benefits in this context are incommensurable, we suggest describing the moral consideration of harms and benefits as a coherent trade-off. Such a decision does not require commensurability. It must be well-informed about the suffering involved and the potential benefits, it must be consistent with the legal, regulatory and institutional framework within which it is made, and it must cohere with other judgments in relevant areas.
