Why restrict medical effective altruism?

Area of Science:

• Bioethics
• Medical Research Ethics
• Public Health

Background:

• Challenge trials involve controlled pathogen exposure to test medical interventions.
• Medical effective altruism (MEA) describes individuals volunteering for public good, accepting risks.
• Bioethicists raised ethical objections to challenge trials, particularly during COVID-19 vaccine development.

Purpose of the Study:

• To critically evaluate the ethical permissibility of risks undertaken by research subjects in challenge trials.
• To address the lack of a clear framework for judging acceptable harm levels in research.
• To examine Alex London's social consistency test for research risks.

Main Methods:

• Analysis of bioethical objections to challenge trials.
• Evaluation of Alex London's social consistency test for research risks.
• Comparison of risks in challenge trials to risks accepted in other societal spheres, specifically volunteer military service.

Main Results:

• The study concludes that the core ethical issue in challenge trials is determining permissible risk levels for subjects.
• Applying the social consistency test, particularly by comparing research risks to those in volunteer military service, suggests no inherent cap on acceptable risks.
• This implies that if societal norms permit soldiers to accept high risks, similar acceptance may extend to research volunteers.

Conclusions:

• The social consistency test, when applied broadly, does not provide a definitive limit on acceptable risks in challenge trials.
• Volunteer military service serves as a relevant social comparison, indicating that research volunteers could permissibly accept significant risks.
• Further development of ethical frameworks is needed to establish clear guidelines for risk assessment in human subject research.
