Human Infection Studies have emerged as an important research approach with the potential to fast track the global development of vaccines and treatments for infectious diseases, including in low resource settings. Given the high level of burdens involved in many HIS, particularly prolonged residency and biological sampling requirements, it can be challenging to identify levels of study payments that provide adequate compensation but avoid ‘undue’ levels of inducement to participate. Through this embedded ethics study, involving 97 healthy volunteers and other (...) research stakeholders in a malaria HIS programme in Kenya, and using in-depth interviews, focus group discussions and observations during and after a malaria HIS, we give a grounded account of ethical issues emerging in relation to study payments in this setting. While careful community, national, international scientific and ethics review processes meant that risks of serious harm were highly unlikely, the levels of motivation to join HIS seen could raise concerns about study payments being too high. Particular value was placed on the reliability, rather than level, of study payment in this setting, where subsistence livelihoods are common. Study volunteers were generally clear about the study aims at the point of recruitment, and this knowledge was retained over a year later, although most reported experiencing more burdens than anticipated at enrolment. Strict study screening procedures, regular clinical and laboratory monitoring of volunteers, with prompt treatment with antimalarial at predetermined endpoints suggested that the risks of serious harm were highly unlikely. Ethical concerns emerged in relation to volunteers’ attempts to conceal symptoms, hoping to prolong residency periods and increase study payments; and volunteers making decisions that compromised important family relationships and personal values. Our findings support an interpretation that, although study volunteers were keen to join the study to access cash payments, they also paid attention to other features of the study and the general clinical research landscape, including levels of risk associated with study participation. Overall, our analysis shows that the ethical concerns emerging from the study payments can be addressed through practical measures, hinged on reducing burdens and strengthening communication, raising important issues for research policy and planning.

Conservative assumptions in medical ethics risk immense harms during a pandemic. Public health institutions and public discourse alike have repeatedly privileged inaction over aggressive medical interventions to address the pandemic, perversely increasing population-wide risks while claiming to be guided by ‘caution’. This puzzling disconnect between rhetoric and reality is suggestive of an underlying philosophical confusion. In this paper, I argue that we have been misled by status quo bias—exaggerating the moral significance of the risks inherent in medical interventions, while systematically (...) neglecting the risks inherent in the status quo prospect of an out-of-control pandemic. By coming to appreciate the possibility and significance of status quo risk, we will be better prepared to respond appropriately when the next pandemic strikes. (shrink)

The idea that payment for research participation can be coercive appears widespread among research ethics committee members, researchers, and regulatory bodies. Yet analysis of the concept of coercion by philosophers and bioethicists has mostly concluded that payment does not coerce, because coercion necessarily involves threats, not offers. In this article we aim to resolve this disagreement by distinguishing between two distinct but overlapping concepts of coercion. Consent-undermining coercion marks out certain actions as impermissible and certain agreements as unenforceable. By contrast, (...) coercion as subjection indicates a way in which someone’s interests can be partially set back in virtue of being subject to another’s foreign will. While offers of payment do not normally constitute consent-undermining coercion, they do sometimes constitute coercion as subjection. We offer an analysis of coercion as subjection and propose three possible practical responses to worries about the coerciveness of payment. (shrink)

In this paper I argue, against the current consensus, that the right to withdraw from research is sometimes alienable. In other words, research subjects are sometimes morally permitted to waive their right to withdraw. The argument proceeds in three major steps. In the first step, I argue that rights typically should be presumed alienable, both because that is not illegitimately coercive and because the general paternalistic motivation for keeping them inalienable is untenable. In the second step of the argument, I (...) consider three special characteristics of the right to withdraw, first that its waiver might be exploitative, second that research involves intimate bodily access, and third that it is irreversible. I argue that none of these characteristics justify an inalienable right to withdraw. In the third step, I examine four considerations often taken to justify various other allegedly inalienable rights: concerns about treating yourself merely as a means as might be the case in suicide, concerns about revoking all your future freedoms in slavery contracts, the resolution of coordination problems, and public interest. I argue that the motivations involved in these four types of situations do not apply to the right to withdraw from research. (shrink)

A number of papers have appeared recently arguing for the conclusion that it is ethically acceptable to infect healthy volunteers with severe acute respiratory syndrome coronavirus 2 as part of research projects aimed at developing COVID-19 vaccines or treatments. This position has also been endorsed in a statement by a working group for the WHO. The papers generally argue that controlled human infection is ethically acceptable if the risks to participants are low and therefore acceptable, the scientific quality of the (...) research is high, the research has high social value, participants give full informed consent, and there is fair selection of participants. All five conditions are necessary premises in the overall argument that such research is ethically acceptable. The arguments concerning risk and informed consent have already been critically discussed in the literature. This paper therefore looks specifically at the arguments relating to condition 3 ‘high social value’ and condition 5 ‘fair selection of participants’ and shows that whereas they may be valid, they are not sound. It is highly unlikely that the conditions that are necessary for ethical CHI trials to take place will be fulfilled. Most, if not all, CHI trials will thus be well intentioned but unethical.

In many countries worldwide, especially in Sub-Saharan Africa, a shortage of physicians limits the provision of lifesaving interventions. One existing strategy to increase the number of physicians in areas of critical shortage is conditioning medical school scholarships on a precommitment to work in medically underserved areas later. Current practice is usually to demand only one year of service for each year of funded studies. We show the effectiveness of scholarships conditional on such precommitment for increasing physician supplies in underserved areas. (...) Then we defend these scholarships against ethical worries that they constitute slavery contracts; rely on involuntary, biased, or unauthorized early consent by a young signatory; put excessive strains on signed commitments; give rise to domination; and raise suspicion of slavery contracts. Importantly, we find that scholarships involving far longer commitment than current practice allows would also withstand these worries. Policymakers should consider introducing conditional scholarships, including long-term versions, as a means to increasing the supply of physicians to medically underserved areas. (shrink)

Clinical investigators must engage in just subject recruitment and selection and avoid unduly influencing research participation. There may be tension between the practice of keeping payments to participants low to avoid undue influence and the requirements of justice when recruiting normal healthy volunteers for phase 1 drug studies. By intentionally keeping payments low to avoid unduly influenced participation, investigators, on the recommendation or insistence of institutional review boards, may be targeting or systematically recruiting healthy adult members of lower socio-economic groups (...) for participation in phase 1 studies. Investigators are at risk of routinely failing to fulfill the obligation of justice, which prohibits the systematic targeting and recruiting of subjects for reasons unrelated to the nature of the study. Insofar as we take seriously the obligation to engage in just subject recruitment and selection, I argue that we must acknowledge the implications low payments might have for subject recruitment and selection and examine the effect of low payments. If low payments de facto target the less well-off for phase 1 studies, we must defend the priority ranking of the obligation to avoid undue influence over the obligation of justice or adopt an alternative recruitment approach. This paper identifies a number of alternatives to the current system of low-value payments to research participants. (shrink)

This article concerns the validity of six canonical rules that institutional review boards use to constrain the behavior of investigators. These rules require investigators to design their studies in a scientifically valid way, not pay their subjects to take risks, minimize risks to their subjects, secure for their subjects access to effective interventions post-trial, not pay their subjects too much and allow their subjects to withdraw from the study unconditionally. Enforcement of these rules is problematic because there are other relationships (...) that seem to be like the investigator-subject relationship in all ethically relevant respects, such as the employer-employee and volunteer organizer-volunteer relationships, to which we would not dream of applying these same rules. Applying these rules in one context but not the others is a violation of ethical consistency I label “exceptionalism.” We should conclude that it is time to reexamine the validity of the six rules.

The gestational surrogate – and her economic and educational vulnerability in particular – is the focus of many of the most persistent worries about paid surrogacy. Those who employ her, and those who broker and organize her services, usually have an advantage over her in resources and information. That asymmetry exposes her to the possibility of exploitation and abuse. Accordingly, some argue for banning paid surrogacy. Others defend legal permission on grounds of surrogate autonomy, but often retain concerns about the (...) surrogate. In response to the dilemma of a ban versus bald permission, we propose a 'soft law' approach: states should require several hours of education of surrogates – education aimed at informing and enhancing surrogate autonomy.

Drawing on empirical evidence in medicine, economics, law, and anthropology, I argue that a market is uniquely capable of meeting the demand for transplantable kidneys, and that it may be arranged so as to operate safely. The welfare gains, expected to accrue to both vendors and recipients, are sufficient to justify sales. Having spelled out the considerations recommending a kidney market, I address the most forceful objections facing the proposal. Despite its currency, the claim that incentives will crowd out altruistic (...) donors and result in a decrease in supply is empirically unsupported and predicated on an implausible view of donorsâ motives. A host of objections claim vendorsâ will not give informed consent. Many such objections identify easily remediable problems, or impose unreasonable standards â standards that would rule out morally permissible kidney donation. And all presuppose a model of morally transformative consent that, I argue, is deficient. Two further challenges point to harms inflicted on those who do not participate in the market. Some claim that those in poverty will be subject to harmful social and legal pressure to vend. This objection fails to distinguish between being pressured to perform a specific act, and being under general economic pressure and having the option to perform an act. It, moreover, presupposes vending more common than is possible. Others worry that the market will give rise to unfair pecuniary externalities. This objection also presupposes that kidney sales will occur more often than is possible. But more importantly, the normative consideration that is supposed to make such externalities especially objectionable, in fact, recommends allowing sales. I also make a political case for kidney sales. I offer an account of the stateâs proper role in the market. I begin with a conception of democratic equality according to which the state is responsible to secure for its citizens the preconditions for democratic participation. I then show that this end would be promoted were the state to end the current prohibition on sales. (shrink)

Scholars and policymakers continue to struggle over the meaning of the word “vulnerable” in the context of research ethics. One major reason for the stymied discussions regarding vulnerable populations is that there is no clear distinction between accounts of research vulnerabilities that exist for certain populations and discussions of research vulnerabilities that require special regulations in the context of research ethics policies. I suggest an analytic process by which to ascertain whether particular vulnerable populations should be contenders for additional regulatory (...) protections. I apply this process to two vulnerable populations: the cognitively vulnerable and the economically vulnerable. I conclude that a subset of the cognitively vulnerable require extra protections while the economically vulnerable should be protected by implementing existing regulations more appropriately and rigorously. Unless or until the informed consent process is more adequately implemented and the distributive justice requirement of the Belmont Report is emphasized and operationalized, the economically disadvantaged will remain particularly vulnerable to the harm of exploitation in research.

Research ethics committees (RECs) evaluate whether the risk-benefit ratio of a study is acceptable. Decentralized clinical trials (DCTs) are a novel approach for conducting clinical trials that potentially bring important benefits for research, including several collateral benefits. The position of collateral benefits in risk-benefit assessments is currently unclear. DCTs raise therefore questions about how these benefits should be assessed. This paper aims to reconsider the different types of research benefits, and their position in risk-benefit assessments. We first propose a categorization (...) of research benefits, based on the types of benefits that can be distinguished from the literature and ethical guidelines. Secondly, we will reconsider the position of collateral benefits. We argue that these benefits are not fundamentally different from other benefits of research and can therefore be included in risk-benefit assessments of DCTs. (shrink)

DNA databases have significant commercial value. Direct-to-consumer genetic testing companies have built databanks using samples and information voluntarily provided by customers. As the price of genetic analysis falls, there is growing interest in building such databases by paying individuals for their DNA and personal data. This paper maps the ethical issues associated with private companies paying for DNA. We outline the benefits of building better genomic databases and describe possible concerns about crowding out, undue inducement, exploitation, and commodification. While certain (...) objections deserve more empirical and philosophical investigation, we argue that none currently provide decisive reasons against using financial incentives to secure DNA samples.

One way to test vaccines is through human challenge trials in which participants are intentionally infected with a contagious organism to expedite the process of assessing the vaccine’s effectiveness. Some experts believe challenge trials may play an important role in fighting COVID-19, especially if the vaccines under current study do not demonstrate sufficient efficacy, if spread of COVID-19 is controlled to a point that radically slows down traditional trials, or if new vaccines need to be rapidly developed for specific subpopulations.1 (...) Challenge trials involve significant time, burden and risk, requiring participants to spend 3–6 weeks in legal quarantine for 24 hours a day in a high-security facility. During this time, no inperson visitors will be allowed, except for very limited inperson contact from researchers collecting necessary data and checks. Following the quarantine period, participants will be asked to attend numerous outpatient follow-up visits over the course of months, to further monitor their response to the vaccine. Participation involves being away from family who may themselves become sick during the global pandemic, as well as potential fear and mental anguish around being a ‘first’ subject. Because there is no definitive treatment for COVID-19, participants could experience serious illness. But even with milder illness, medical experts know very little about the long-term consequences of COVID-19 infection. This raises the question of how much people should be paid for their participation in COVID-19 challenge trials. Most think participants should be paid something, but many contend that we should be …. (shrink)

Controlled Human Infection Model (CHIM) research involves the infection of otherwise healthy participants with disease often for the sake of vaccine development. The COVID-19 pandemic has emphasised the urgency of enhancing CHIM research capability and the importance of having clear ethical guidance for their conduct. The payment of CHIM participants is a controversial issue involving stakeholders across ethics, medicine and policymaking with allegations circulating suggesting exploitation, coercion and other violations of ethical principles. There are multiple approaches to payment: reimbursement, wage (...) payment and unlimited payment. We introduce a new Payment for Risk Model, which involves paying for time, pain and inconvenience and for risk associated with participation. We give philosophical arguments based on utility, fairness and avoidance of exploitation to support this. We also examine a cross-section of the UK public and CHIM experts. We found that CHIM participants are currently paid variable amounts. A representative sample of the UK public believes CHIM participants should be paid approximately triple the UK minimum wage and should be paid for the risk they endure throughout participation. CHIM experts believe CHIM participants should be paid more than double the UK minimum wage but are divided on the payment for risk. The Payment for Risk Model allows risk and pain to be accounted for in payment and could be used to determine ethically justifiable payment for CHIM participants.Although many research guidelines warn against paying large amounts or paying for risk, our empirical findings provide empirical support to the growing number of ethical arguments challenging this status quo. We close by suggesting two ways (value of statistical life or consistency with risk in other employment) by which payment for risk could be calculated. (shrink)

The Food and Drug Administration and the European Medicines Agency have launched a recent initiative to enhance collaboration in research, with the intent to “ensure that clinical trials submitted in drug marketing applications in the United States and European Union are conducted uniformly, appropriately, and ethically.” This initiative recalls efforts from two decades ago when the United States, the European Union and Japan formed the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use as a (...) mechanism for harmonizing clinical research regulations. The intent of harmonization was to improve patients’ “access to new drugs, to prevent unnecessary global development delays and to avoid animal and human study duplications” through policy reconciliation.FDA/EMA efforts at collaboration call for a reassessment of past harmonization efforts: to what extent are ICH member policies already synchronized and to what extent can they be harmonized in the future? This paper will focus on these questions through the lens of pediatric investigation. (shrink)

Significant attention has been given both to the ethics of Controlled Human Infection Model research and the ethics of payment for research participation. However, comparatively little attention has been given to the ethics of paying for participation specifically in CHIM research. Grimwade et al should be commended for thoughtfully addressing this topic and especially for the empirical data collection informing their work, which is too often lacking in discussions of payment for research participation. In what follows I will discuss three (...) relatively subtle factors that, I believe, make a difference to the ethical analysis of paying for research participation and raise what I intend to be constructive questions about the extent to which the survey instrument employed by the authors captures them. The authors focus on payment for risk in CHIM research. They correctly stress that compensating participants for risk is controversial and that “many general guidelines warn against paying for the risk in medical research”. While not all guidance documents share this scepticism,1 compensating for risk raises thorny issues and uncertainty over the topic among IRBs and regulatory bodies is likely to hinder the practice. Part of the difficulty in assessing payment for research risks stems from the way in which subtle variances in background assumptions influence the ethical assessment, which also complicates empirical attempts to measure attitudes on the topic. Most importantly, it is crucial to be precise about background assumptions concerning whether participants are protected from bearing the financial burdens of research risks that eventuate in actual harms. Protective mechanisms …. (shrink)

Concerns about exploitation pervade the literature on commercial cross-border reproductive care, particularly egg selling and surrogacy. But what constitutes exploitation, and what moral weight does it have? I consider the relationship between vulnerability, limited choice, consent, and mutually advantageous exploitation. To elucidate the difference between limited choice and consent, I draw on an account of relational autonomy. In the absence of a normative principle of fair distribution, it is unclear whether the providers of reproductive goods and services are treated fairly (...) in such contracts, and therefore whether they have been exploited. I finish with some pragmatic recommendations for minimizing risks and empowering egg sellers and surrogates. (shrink)

In 2004 and 2005, Woo-Suk Hwang achieved international stardom with publications in Science reporting on successful research involving the creation of stem cells from cloned human embryos. The wonder and success all began to unravel, however, when serious ethical concerns were raised about the source of the eggs for this research. When the egg scandal had completely unfolded, it turned out that many of the women who provided eggs for stem cell research had not provided valid consents and that nearly (...) 75% of the women egg providers had received cash or in-kind payments. Among those who did not receive direct benefits, some cited patriotism as their reason for participating in embryonic stem cell research, hence the question “for love or money?”—namely, patriotism versus payment. This paper summarizes the Hwang debacle with particular attention to the egg scandal and ends with some preliminary thoughts on patriotism as a motive for research participation. (shrink)

In order to reach its full potential, human embryonic stem cell (hESC) research requires the use of human oocytes. There is currently a shortage of human eggs for research, and this shortage is likely to continue, as many states and countries prohibit their sale for research purposes, while at the same time condoning unregulated markets for oocytes for use in assisted reproduction. In this essay I first explore possible alternative sources of oocytes for hESC research and conclude that, at present, (...) women are the best source. I then examine arguments about exploitation and commodification that are often raised to prohibit payment to women for oocytes in both the reproductive and research contexts and find these arguments wanting. I conclude by suggesting that ethical concerns raised about a market in oocytes do not warrant a prohibition on the sale of eggs, but that a regulated market can consistently minimize ethical concerns while respecting women and providing important resources for advances in hESC research.

Paying research participants in developing countries like Uganda raises ethical concerns over potential for undue inducement. This article, based on an exploratory study, reviewed 49 research protocols from a national HIV/AIDS research ethics committee database. Payments mainly adhered to the reimbursement and compensation payment models. Offers made were diverse but basic in order to limit undue inducement. Implications in terms of undue inducement and possible impact on participants and research are discussed. We end by recommending standardization across comparable studies in (...) the interests of promoting high-quality research, altruism, voluntariness, and restraining unfair reimbursement practices in research.

Human infection challenge studies (HCS) involve intentionally infecting research participants with pathogens (or other micro-organisms). There have been recent calls for more HCS to be conducted in low-income and middle-income countries (LMICs), where many relevant diseases are endemic. HCS in general, and HCS in LMICs in particular, raise numerous ethical issues. This paper summarises the findings of a project that explored ethical and regulatory issues related to LMIC HCS via (i) a review of relevant literature and (ii) 45 qualitative interviews (...) with scientists and ethicists. Among other areas of consensus, we found that there was widespread agreement that LMIC HCS can be ethically acceptable, provided that they have a sound scientific rationale, are accepted by local communities and meet usual research ethics requirements. Unresolved issues include those related to (i) acceptable approaches to trade-offs between the scientific aim to produce generalisable results and the protection of participants, (iii) the sharing of benefits with LMIC populations, (iii) the acceptable limits to risks and burdens for participants, (iv) the potential for third-party risk and whether the degree of acceptable third-party risk is different in endemic settings, (v) the conditions under which (if any) it would be appropriate to recruit children for disease-causing HCS, (v) appropriate levels of payment to participants and (vi) appropriate governance of (LMIC) HCS. This paper provides preliminary analyses of these ethical considerations in order to (i) inform scientists and policymakers involved in the planning, conduct and/or governance of LMIC HCS and (ii) highlight areas warranting future research. Insofar as this article focuses on HCS in (endemic) settings where diseases are present and/or widespread, much of the analysis provided is relevant to HCS (in HICs or LMICs) involving pandemic diseases including COVID19.

ABSTRACT There are disagreements among ethicists on what comprises an “appropriate” good to offer research participants. Debates often focus on the type, quantity, timing, and ethical appropriateness of such offers, particularly in settings where participants may be socio-economically vulnerable, such as in parts of Zambia. This was a Cross-sectional online survey of researchers and Research Ethics Committees (RECs) designed to understand practices, attitudes and policies associated with provision of goods to research participants. Of 122 responding researchers, 69 met eligibility criteria. (...) Responses were also received from five of the six Zambian RECs involved in reviewing research proposals. Forty-nine researchers (71.0%) confirmed previous experience offering goods to participants. Of these, 21 (42.9%) offered participants money only, 18 (36.7%) offered non-monetary goods, while the rest offered both monetary and non-monetary goods. Generally, goods were offered and approved by RECs to compensate for time, lost wages and transportation. One REC and 34.8% of researchers reported being subject to an institutional policy on offering goods to participants. While reimbursement is the main reason for offering goods to participants in Zambia, caution is required when deciding on the type and quantity of goods to offer given the potential for community mistrust and manipulation.

Vulnerability in research is often understood as a diminished ability to protect one's own interests, manifested by a compromised capacity to give informed or voluntary consent. Certain groups of people are thought to be more vulnerable than others and therefore are at risk of being exploited or mistreated in research. Accordingly, the federal regulations call for additional safeguards to protect vulnerable groups.There remains some ambiguity and contradiction, however, regarding what groups are vulnerable in research and why,3 since the available codes (...) of research ethics and regulations describe many groups as vulnerable. When so many groups are considered vulnerable, but no specification is offered as to how they are vulnerable or what particular protections are appropriate, the possibility of meaningful safeguards is diminished. In addition, current concepts of vulnerability are usually applied to whole groups of people, without distinguishing between individuals in a group who might truly have a compromised capacity to protect their own interests from those who do not.

In order to continue to maintain public trust and confidence in human research, participants must be treated with respect. Researchers and Human Research Ethics Committee members need to be aware that modern considerations of this value include: the need for a valid consenting process, the protection of participants who have their capacity for consent compromised; the promotion of dignity for participants; and the effects that human research may have on cultures and communities. This paper explains the prominence of respect as (...) a value when considering the ethics of human research and provides practical advice for both researchers and Human Research Ethics Committee members in developing respectful research practices.

Participant safety and data integrity, critical in trials of new investigational drugs, are achieved through honest participant report and precision in the conduct of procedures. HIV prevention post-trial access studies in middle-income countries potentially offer participants many benefits including access to proven efficacious but unlicensed technologies, ancillary care that often exceeds local standards-of-care, financial reimbursement for participation and possibly unintended benefits if participants choose to share or sell investigational drugs. This case study examines the possibility that this combination of benefits (...) may constitute an undue inducement for some participants in middle-income countries, where economic challenges are prevalent. A case study is presented of a single participant in a cohort of 382 participants who used concealment, fabrication and deception to ensure eligibility for a post-trial access study of an unlicensed HIV prevention technology at potential risk to her health and that of her fetus. A root cause analysis revealed her desire to access HIV prevention during an unplanned pregnancy with a partner whose faithfulness was in question.

Supervised injectable opioid assisted treament prescribes injectable opioids to individuals for whom other forms of addiction treatment have been ineffective. In this article, we examine arguments that opioid-dependent people should be assumed incompetent to voluntarily consent to clinical research on siOAT unless proven otherwise. We agree that concerns about competence and voluntary consent deserve careful attention in this context. But we oppose framing the issue solely as a matter of the competence of opioid-dependent people and emphasize that it should be (...) considered in the context of inequities in access to siOAT as a medical treatment. Consequently, we suggest that bioethics literature on nonexploitation, which focuses on clinical research in low-income countries, is helpful due to locating ethical issues within systemic social conditions. Finally, we consider the implications of our argument for the ethics of clinical research on siOAT. (shrink)

Lowering compensation to research subjects to protect them from “undue inducement” is a misguided attempt to shoehorn a concern about exploitation into the framework of autonomy. We suggest that oversight bodies should be less concerned about undue influence than about exploitation of subjects. Avoiding exploitation in human subjects research requires not only increasing compensation, but enhancing the dignity of research participation.
