In this article I examine several criticisms of the concept of vulnerability. Rather than rejecting the concept, however, I argue that a sufficiently rich understanding of vulnerability is essential to bioethics. The challenges of international research in developing countries require an understanding of how new vulnerabilities arise from conditions of economic, social and political exclusion. A serious shortcoming of current conceptions of vulnerability in research ethics is the tendency to treat vulnerability as a label fixed on a particular subpopulation. My (...) paper examines the role of this “label” metaphor in current statements of research ethics. In contrast to this prevailing “label” metaphor, my own positive account of vulnerability develops a dynamic way of understanding the structure of the concept of vulnerability based on the idea of “layers of vulnerability.” I examine several cases involving women, as they are sometimes labeled as a vulnerable population and sometimes not. My analysis demonstrates the essential role of this revised concept of vulnerability in bioethics and research ethics. (shrink)

Concern for human vulnerability seems to be at the heart of bioethical inquiry, but the concept of vulnerability is under-theorized in the bioethical literature. The aim of this article is to show why bioethics needs an adequately theorized and nuanced conception of vulnerability. We first review approaches to vulnerability in research ethics and public health ethics, and show that the bioethical literature associates vulnerability with risk of harm and exploitation, and limited capacity for autonomy. We identify some of the challenges (...) emerging from this literature: in particular, how to reconcile universal human vulnerability with a context-sensitive analysis of specific kinds and sources of vulnerability; and how to reconcile obligations to protect vulnerable persons with obligations to respect autonomy. We then briefly survey some of the theoretical resources available within the philosophical literature to address these challenges, and to assist in understanding the conceptual connections between vulnerability and related concepts such as harm, exploitation, needs, and autonomy. We also sketch out a taxonomy of sources and kinds of vulnerability. Finally, we consider the implications for policy evaluation of making vulnerability an explicit and central focus of bioethics. Our investigation is in the form of a broad survey motivating a research agenda rather than a detailed analysis. (shrink)

Alongside globalization, the sense of vulnerability among people and populations has increased. We feel vulnerable to disease as new infections spread rapidly across the globe, while disasters and climate change make health increasingly precarious. Moreover, clinical trials of new drugs often exploit vulnerable populations in developing countries that otherwise have no access to healthcare and new genetic technologies make people with disabilities vulnerable to discrimination. Therefore the concept of vulnerability has contributed new ideas to the debates about the ethical dimensions (...) of medicine and healthcare. This book explains and elaborates the new concept of vulnerability in today s bioethics. Firstly, Henk ten Have argues that vulnerability cannot be fully understood within the framework of individual autonomy that dominates mainstream bioethics today: it is often not the individual person who is vulnerable, rather that his or her vulnerability is created through the social and economic conditions in which he or she lives. Contending that the language of vulnerability offers perspectives beyond the traditional autonomy model, this book offers a new approach which will enable bioethics to evolve into a global enterprise. This groundbreaking book critically analyses the concept of vulnerability as a global phenomenon. It will appeal to scholars and students of ethics, bioethics, globalization, healthcare, medical science, medical research, culture, law, and politics.". (shrink)

Traditional accounts of vulnerability tend to label entire populations as vulnerable. This approach is of limited utility. Instead, this article utilizes a layered approach to vulnerability, identifying multiple vulnerabilities that older people experience. It focuses on distinguishing the different layers of vulnerability that may be experienced by the elderly in middle-income countries of Latin America. In doing so, I show how the layered approach to vulnerability functions, and demonstrate why it is more interesting and useful than the traditional approach. The (...) article achieves three things. First, it unwraps the different potential layers of vulnerability that develop in old age and the multidimensionality aspects of aging. Second, it reestablishes the usefulness of the concept of vulnerability and explains its functioning. Finally, it shows how different policies can be designed in order to address each vulnerability layer. The layered account promotes a multifaceted approach to public policy analyses and design. In this sense, the layered concept of vulnerability is an appealing concept to consider in public health ethics. (shrink)

Vulnerability is one of the least examined concepts in research ethics. Vulnerability was linked in the Belmont Report to questions of justice in the selection of subjects. Regulations and policy documents regarding the ethical conduct of research have focused on vulnerability in terms of limitations of the capacity to provide informed consent. Other interpretations of vulnerability have emphasized unequal power relationships between politically and economically disadvantaged groups and investigators or sponsors. So many groups are now considered to be vulnerable in (...) the context of research, particularly international research, that the concept has lost force. In addition, classifying groups as vulnerable not only stereotypes them, but also may not reliably protect many individuals from harm. Certain individuals require ongoing protections of the kind already established in law and regulation, but attention must also be focused on characteristics of the research protocol and environment that present ethical challenges.

The elderly are often considered a vulnerable group in public and academic bioethical debates and regulations. In this paper, we examine and challenge this assumption and its ethical implications. We begin by systematically delineating the different concepts of vulnerability commonly used in bioethics, before then examining whether these concepts can be applied to old age. We argue that old age should not, in and of itself, be used as a marker of vulnerability, since ageing is a process that can develop (...) in a variety of different ways and is not always associated with particular experiences of vulnerability. We, therefore, turn to more fundamental phenomenological considerations in order to reconstruct from a first person perspective the intricate interconnections between the experiences of ageing and vulnerability. According to this account, ageing and old age are phenomena in which the basic anthropological vulnerability of human beings can manifest itself in an increased likelihood of harm and exploitation. Thus, we plead for a combined model of vulnerability that helps to avoid problems related to the current concepts of vulnerability. We conclude first that old age as such is not a sufficient criterion for being categorized as vulnerable in applied ethics, and second that reflections on ageing can help to develop a better understanding of the central role of vulnerability in human existence and in applied ethics.

BackgroundVulnerability is a key concept in traditional and contemporary bioethics. In the philosophical literature, vulnerability is understood not only to be an ontological condition of humanity, but also to be a consequence of contingent factors. Within bioethics debates, vulnerable populations are defined in relation to compromised capacity to consent, increased susceptibility to harm, and/or exploitation. Although vulnerability has historically been associated with older adults, to date, no comprehensive or systematic work exists on the meaning of their vulnerability. To fill this (...) gap, we analysed the literature on aged care for the meaning, foundations, and uses of vulnerability as an ethical concept.MethodsUsing PRISMA guidelines, we conducted a systematic review of argument-based ethics literature in four major databases: PubMed, Embase®, Web of Science™, and Philosopher’s Index. These covered biomedical, philosophy, bioethical, and anthropological literature. Titles, abstracts, and full texts of identified papers were screened for relevance. The snowball technique and citation tracking were used to identify relevant publications. Data analysis and synthesis followed the preparatory steps of the coding process detailed in the QUAGOL methodology.ResultsThirty-eight publications met our criteria and were included. Publication dates ranged from 1984 to 2020, with 17 publications appearing between 2015 and 2020. Publications originated from all five major continents, as indicated by the affiliation of the first author. Our analyses revealed that the concept of vulnerability could be distinguished in terms of basic human and situational vulnerability. Six dimensions of older adults’ vulnerability were identified: physical; psychological; relational/interpersonal; moral; sociocultural, political, and economic; and existential/spiritual. This analysis suggested three ways to relate to older adults’ vulnerability: understanding older adults’ vulnerability, taking care of vulnerable older adults, and intervening through socio-political-economic measures.ConclusionsThe way in which vulnerability was conceptualised in the included publications overlaps with distinctions used within contemporary bioethics literature. Dimensions of aged care vulnerability map onto defining features of humans, giving weight to the claim that vulnerability represents an inherent characteristic of humans. Vulnerability is mostly a value-laden concept, endowed with positive and negative connotations. Most publications focused on and promoted aged care, strengthening the idea that care is a defining practice of being human. (shrink)

The concept of vulnerability has been hotly debated in research ethics literature. Some critics considered it a useless concept. In 2009—against some of those criticisms—I defended the importance of understanding this concept in terms of layers instead of applying it as a label given to certain subpopulations. In this paper, I present some of the limits of this analysis and I also explore the similarities and differences this approach has when compared to using a taxonomy as another answer on how (...) to assess vulnerability. I present the notion of cascade vulnerability and underscore the dispositional character of layers and their relevance to identify and evaluate layers of vulnerability. Finally, I show how this layered account has been incorporated in important documents such as the new 2016 CIOMS-WHO Guidelines. (shrink)

This short article is a commentary to ‘Vulnerability in Research Ethics: A way forward’ from Margaret Meek Lange, Wendy Rogers and Susan Dodds. In their article they describe and accept my criticisms of the subpopulation approach to vulnerability and my analysis of vulnerability based on layers, but they suggest going beyond it using a taxonomy to classify layers of vulnerabilty. I argue that a) we do not need a taxonomy to classify vulnerabilities, b) the authors do not provide an adequate (...) or successful taxonomy, and c) they are unable to link their taxonomy to specific obligations. Thus I propose avoiding an approach that requires taxonomies, and suggest instead using some characteristics of layers of vulnerability. (shrink)
