To reduce the global burden of the COVID-19 pandemic, there is an urgent need to develop a safe vaccine. Vaccine development usually takes many years as it goes through several different phases. To hasten COVID-19 vaccine development, it has been suggested that the final stage could be replaced with a human challenge trial. Volunteers would be intentionally infected with SARS-CoV-2 to see how the vaccine candidate works. To intentionally infect a healthy human being with a potentially deadly virus is contrary (...) to the highest ethical standards in medical research. This article highlights the benefits and risks of COVID-19 HCTs and summarises what research ethics committees need to consider during the ethical assessment of such trials including risk reduction, strict containment measures, specific informed consent measures and avoiding high monetary inducements.

Biobanking can promote valuable health research that may lead to significant societal benefits. However, collecting, storing and sharing human samples and data for research purposes present numerous ethical challenges. These challenges are exacerbated when the biobanking efforts aim to facilitate research on public health emergencies and include the sharing of samples and data between low/middle-income countries (LMICs) and high-income countries (HICs). In this article, we explore ethical challenges for COVID-19 biobanking, offering examples from two past infectious disease outbreaks in LMICs (...) where biobanking activities contributed to the perpetuation of global inequities. We focus on how the ethical imperative to promote the common good during public health emergencies can conflict with protecting the interests of biobank participants. We discuss how conducting biobank research under a waiver of informed consent during public health emergencies is ethically permissible, provided guidance is in place to prevent biopiracy and exploitation of vulnerable communities. We also highlight the need for biobank collaborations between LMICs and HICs to promote capacity building and benefit sharing. Finally, we offer guidance to promote the ethical oversight of biobanks and biobank research during the COVID-19 pandemic or other future public health emergencies. (shrink)

The success of digital COVID-19 contact tracing requires a strategy that successfully addresses the digital divide—inequitable access to technology such as smartphones. Lack of access both undermines the degree of social benefit achieved by the use of tracing apps, and exacerbates existing social and health inequities because those who lack access are likely to already be disadvantaged. Recently, Singapore has introduced portable tracing wearables (with the same functionality as a contact tracing app) to address the equity gap and promote public (...) health. We argue that governments have an ethical obligation to ensure fair access to the protective benefits of contract tracing during the pandemic and that wearables are an effective way of addressing some important equity issues. The most contentious issues about contact tracing apps have been the potential infringements of privacy and individual liberty, especially where the use of apps or other technology (such as wearables or QR codes) is required for access to certain spaces. Here we argue that wearables, as opposed to apps alone, will make a digital contact tracing mandate more practical and explain some conditions under which such a mandate would be justified. We focus on Singapore as a case study that has recently deployed contact tracing wearables nationally, but also reference debate about wearables in Australia and New Zealand. Our analysis will be relevant to counties trialling similar portable tracing wearables. (shrink)

In response to the COVID-19 pandemic, large-scale research and pharmaceutical regulatory processes have proceeded at a dramatically increased pace with new and effective, evidence-based COVID-19 interventions rapidly making their way into the clinic. However, the swift generation of high-quality evidence and the efficient processing of regulatory authorisation have given rise to more specific and complex versions of well-known research ethics issues. In this paper, we identify three such issues by focusing on the authorisation of Molnupiravir, a novel antiviral medicine aimed (...) at reducing the ability of SARS-CoV-2 to multiply in the body, for clinical use by the National Health Service in England and the concomitant testing of Molnupiravir through the large-scale PANORAMIC randomised control trial. By analysing the ways in which the authorisation and clinical use of Molnupiravir complicate standard approaches to clinical equipoise, standard of care, and participant consent in the PANORAMIC randomised control trial we will explain some of ethical implications for clinical trials that aim to study the efficacy and safety of new COVID-19 and other therapeutics when conditional authorisation has already been granted and when such treatments have already been made available to patients by national health providers.

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.

It has been proposed that the urgency of having a vaccine as a response to SARS-CoV-2 is so great, given the potential health, economic and social benefits that we should override the established s...

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)

Currently, millions of minors are being inoculated against SARS-CoV-2 in many countries in the world. Ethical concerns about clinical research involving children have barely been addressed in the literature, despite the fact that the paediatric population is particularly vulnerable within this context. Children should be included in the research plans for COVID-19 vaccines. Nevertheless, it is necessary to critically assess to what extent clinical trials are being conducted according to methodological and ethical criteria that allow us to conclude that the (...) results are valid and, in consequence, how far the vaccination plans for children are scientifically justified.The principal aim of this article is to analyse critically the process of clinical research on COVID-19 vaccines involving children, highlighting the ethical concerns that arise, including the need to stratify the results from older adolescents separately for analysis before proceeding, if further research is warranted, in descending age order. The development of COVID-19 vaccines is examined, with a special look at the participation of children throughout their clinical development, including a review of the clinical trials registered in three international databases. We also offer some additional considerations about the inclusion of minors in vaccination plans. Finally, we conclude with some recommendations, with particular emphasis on the following ethical duties: research in children should be carried out only once the relevant research in adults has previously been conducted; issues that concern children’s needs and rights should be specifically addressed; and, therefore, the highest standards of ethical and scientific quality should be met.

TB human challenge studies could accelerate TB vaccine development by reducing uncertainty in early-stage vaccine testing, selecting promising vaccine candidates for large-scale field trials, and identifying an immune correlate of protection. However, ethical concerns regarding the exposure of trial participants and bystanders to significant risk have been a limiting factor for TB human challenge models. We analyze the expected social value and risks of different types of TB human challenge models, and conclude that given the massive public health burden of (...) TB, challenge models with even scant probabilities of expediting TB vaccine authorization have enormous expected humanitarian value, saving between 33,000 and 1,375,000 lives over the next ten years. We argue that attenuated M.tb challenge trials can be conducted ethically, and discuss the benefits and drawbacks of conducting virulent M.tb challenge trials. (shrink)
