Protection, health seeking, or a laissez-passer: Participants’ decision-making in an EVD vaccine trial in the eastern Democratic Republic of the Congo

During the 10th Ebola virus disease (EVD) epidemic in the eastern Democratic Republic of the Congo (DRC) (2018–2020), two experimental EVD vaccines were deployed in North Kivu. This province has been at the centre of conflict in the region for the last 25 years. Amidst ambivalence towards protracted foreign intervention and controversy about introducing two experimental vaccines, the existing literature has focused on mistrust and ‘resistance’ towards the Ebola response and vaccines. In this article, we examine why people in the eastern DRC did decide to volunteer for a trial of a second EVD vaccine in North Kivu, despite the controversy. Drawing on ethnographic observation, interviews, and focus groups with trial participants conducted between September 2020 and April 2021, we analyse three motivations for participating: protection, health seeking, and expectations surrounding travel requirements. We make three points. First, participation in vaccine trials may be understood locally to have advantages which have not been considered by the trial, because they go beyond medical considerations and are specific to a particular social setting. Second, despite much of the literature focusing on a causal relationship between rumours and ‘vaccine hesitancy’, some rumours may in fact encourage participation. Third, material objects associated with trial participation - such as participant vaccine cards - can hold social and political meaning beyond the confines of the vaccine clinic, and influence decisions surrounding participation. Empirical investigation of how medical interventions become entangled in political economies is essential to understanding the perceived functions of participation, and thus the reasons why people volunteer in clinical trials. Participants' narratives about their decision-making provide an insight into how international bioethical debates interact with, but may also stand apart from, the situated social and economic realities driving decision-making around clinical trials on the ground. This highlights the need for ethical approaches that foreground the political, social, and economic context

The politics of the second vaccine: debates surrounding ebola vaccine trials in the Eastern Democratic Republic of the Congo

Two experimental Ebola vaccines were deployed during the tenth Ebola epidemic (2018–20) in the Democratic Republic of the Congo (DRC). The first, the Ervebo vaccine manufactured by Merck, was used as part of a ring vaccination in the epicentre of the epidemic in North Kivu. In 2019, the prime- (Ad26.ZEBOV) and boost- (MVA-BN-Filo) vaccine manufactured by Johnson & Johnson (J&J) became the second vaccine against Ebola, deployed by the DRC-EB-001 vaccine trial in Goma, North Kivu. There was international debate as to the value and ethics of testing a second vaccine in an epidemic context. This article examines how this debate unfolded among actual and potential DRC-EB-001 trial participants in Goma. Drawing on ethnographic observation, interviews and focus groups, it explores how the trial was perceived and contested on the ground and situated in broader debates about the ethics of clinical trials, especially during the COVID-19 pandemic. We illustrate how debates around the ethics of clinical research are not simply centred on bioethical principles but are inseparable from local political dynamics and broader contests about governance, inequality and exclusion
