  1. The Ethics of Human Challenge Trials Using Emerging SARS-CoV-2 Virus Variants.Abie Rohrig & Nir Eyal - manuscript
    The world’s first COVID-19 human challenge trial using the D614G strain of SARS-CoV-2 is underway in the United Kingdom. The Wellcome Trust is funding challenge stock preparation of the Beta variant (B.1.351) for a follow-up human challenge trial, and researchers at Imperial College London are considering conducting that trial. However, little has been written thus far about the ethical justifiability of human challenge trials with SARS-CoV-2 variants of concern. While vaccine resistance as such does not increase risks for volunteers in (...)

  2. Ethical Considerations for International Recruitment in COVID-19 Human Challenge Trials.Kaleem Ahmid, Abie Rohrig, Paul Ndebele, Zacharia Kafuko & Josh Morrison - manuscript
    Ongoing and anticipated COVID-19 human challenge studies in the UK may advance our understanding of COVID-19 and facilitate the licensure of safe, effective, and easily deployable next-generation COVID-19 vaccines and boosters. We argue that international volunteer recruitment for COVID-19 human challenge trials can help promote diversity in these trials and ensure a sufficient number of eligible volunteers, both of which will increase the benefits of challenge research. We explore the ethical ramifications of dealing with unfair background conditions of global vaccine (...)
