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)

Twenty-five years after the term "therapeutic misconception’ (TM) first entered the literature, most commentators agree that it remains widespread. However, the majority of scholarly attention has focused on the reasons why a patient cum human subject might confuse the goals of research with the goals of therapy. Although this paper addresses the social and cultural factors that seem to animate the TM among subjects, it also fills a niche in the literature by examining why investigators too might operate under a (...) similar confusion. In framing these issues, the paper expressly adopts a Wittgensteinian approach to evaluating the TM, suggesting that interlocutors do not need any analytic definition of the TM to use the term meaningfully in thinking about the moral implications of the TM in practice.

Despite broad agreement that the vulnerable have a claim to special protection, defining vulnerable persons or populations has proved more difficult than we would like. This is a theoretical as well as a practical problem, as it hinders both convincing justifications for this claim and the practical application of required protections. In this paper, I review consent-based, harm-based, and comprehensive definitions of vulnerability in healthcare and research with human subjects. Although current definitions are subject to critique, their underlying assumptions may (...) be complementary. I propose that we should define vulnerability in research and healthcare as an identifiably increased likelihood of incurring additional or greater wrong. In order to identify the vulnerable, as well as the type of protection that they need, this definition requires that we start from the sorts of wrongs likely to occur and from identifiable increments in the likelihood, or to the likely degree, that these wrongs will occur. It is limited but appropriately so, as it only applies to special protection, not to any protection to which we have a valid claim. Using this definition would clarify that the normative force of claims for special protection does not rest with vulnerability itself, but with pre-existing claims when these are more likely to be denied. Such a clarification could help those who carry responsibility for the protection of vulnerable populations, such as Institutional Review Boards, to define the sort of protection required in a more targeted and effective manner.

This article reflects on the relevance and applicability of the Belmont Report nearly four decades after its original publication. In an exploration of criticisms that have been raised in response to the report and of significant changes that have occurred within the context of biomedical research, five primary themes arise. These themes include the increasingly vague boundary between research and practice, unique harms to communities that are not addressed by the principle of respect for persons, and how growing complexity and (...) commodification in research have shed light on the importance of transparency. The repercussions of Belmont's emphasis on the protection of vulnerable populations is also explored, as is the relationship between the report's ethical principles and their applications. It is concluded that while the Belmont Report was an impressive response to the ethical issues of its day, the field of research ethics involving human subjects may have outgrown it. (shrink)

This article explores the plausibility of an argument against embryonic stem cell research based on what the regulations already say about research on pregnant women and fetuses. The center of the argument is the notion of vulnerability and whether such a concept is applicable to human embryos. It is argued that such an argument can be made plausible. The article concludes by responding to several important objections.

Institutional review boards, tasked with facilitating ethical research, are often pulled in competing directions. In what we call the protection-inclusion dilemma, we acknowledge the tensions IRBs face in aiming to both protect potential research participants from harm and include under-represented populations in research. In this manuscript, we examine the history of protectionism that has dominated research ethics oversight in the United States, as well as two responses to such protectionism: inclusion initiatives and critiques of the term vulnerability. We look at (...) what we know about IRB decision-making in relation to protecting and including “vulnerable” groups in research and examine the lack of regulatory guidance related to this dilemma, which encourages protection over inclusion within IRB practice. Finally, we offer recommendations related to how IRBs might strike a better balance between inclusion and protection in research ethics oversight. (shrink)

Abstract:Vulnerability is an important criterion to assess the ethical justification of the inclusion of participants in research trials. Currently, vulnerability is often understood as an attribute inherent to a participant by nature of a diagnosed condition. Accordingly, a common ethical concern relates to the participant’s decisionmaking capacity and ability to provide free and informed consent. We propose an expanded view of vulnerability that moves beyond a focus on consent and the intrinsic attributes of participants. We offer specific suggestions for how (...) relational aspects and the dynamic features of vulnerability could be more fully captured in current discussions and research practices. (shrink)

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)

In connection with research on humans, the term “vulnerability” is only appropriate to identify the special need for protection of certain sections of the population and individuals, if this term refers to the additional risk of certain groups of subjects. Authors who focus on the additional risk suffering of a subject group when defining vulnerability succeed in considering the specific worthiness of protection in a context-sensitive way. The attempt to define the risk–benefit assessment for vulnerable subject groups on a binding (...) basis faces considerable difficulties. This assessment depends both on the research situation and on the test subject. The normative aspect of this decision could be solved by referring to Rawl’s decision model of an original position. In cases where there is no benefit for the subject, arguments in the discussion of the risks and benefits that are based on a “group or overall benefit” and an “objective interest,” cannot be fully sustained.

Background Notwithstanding the need to produce evidence-based knowledge on medications for pregnant women, they remain underrepresented in clinical research. Sometimes they are excluded because of their supposed vulnerability, but there are no universally accepted criteria for considering pregnant women as vulnerable. Our aim was to explore whether and if so to what extent pregnant women are vulnerable as research subjects. Method We performed a conceptual and empirical analysis of vulnerability applied to pregnant women. Analysis A conceptual analysis supports Hurst's definition (...) of vulnerability. Consequently, we argue that pregnant women are vulnerable if they encounter an identifiably increased likelihood of incurring additional or greater wrong. According to the literature, this increased likelihood could exist of four alleged features for pregnant women's vulnerability: informed consent, susceptibility to coercion, higher exposure to risk due to lack of knowledge, vulnerability of the fetus. Discussion Testing the features against Hurst's definition demonstrates that they all concern the same issue: pregnant women are only vulnerable because a higher exposure to risk due to lack of scientific knowledge comprises an increased wrong. Research Ethics Committees have a responsibility to protect the vulnerable, but a higher exposure to risk due to lack of scientific knowledge is a much broader issue and also needs to be addressed by other stakeholders. Conclusions The only reason why pregnant women are potentially vulnerable is to the extent that they are increasingly exposed to higher risks due to a lack of scientific knowledge. Accordingly, the discussion can advance to the development of practical strategies to promote fair inclusion of pregnant women in clinical research. (shrink)

This paper attempts to philosophically articulate empirical evidence on the positive effects of illness within the wider context of a discussion of the positive aspects of vulnerability. The conventional understanding holds that to be vulnerable is to be open to harms and wrongs; it is to be fragile, defenseless, and of compromised autonomy. In this paper, we challenge the assumption that vulnerability consists of nothing but powerlessness and dependence on others. This paper attempts to: (1) outline the theoretical conceptualisation of (...) the positive aspects of coping with illness, while simultaneously showing how these findings provide empirical support for some classical philosophical ideas; (2) influence a change in the manners in which the ill are usually perceived (as weak, dependent, robbed of a good life) and (3) point to the importance of modernising the prevalent biomedical conception of illness with the subjective dimension of health. Biomedical understanding of illness focuses on the vulnerable experience of the sufferer, suggesting the importance of philosophical additions. (shrink)
