Who Should Get the Influenza Vaccine When Not All Can?
"The potential threat of pandemic influenza is staggering: 1.9 million deaths, 90 million people sick, and nearly 10 million people hospitalized, with almost 1.5 million requiring intensive-care units (ICUs) in the United States...Clear ethical justification for vaccine priorities is essential to the acceptability of the priority ranking and any modifications during the pandemic. With limited vaccine supply, uncertainty over who will be at highest risk of infection and complications, and questions about which historic pandemic experience is most applicable, society faces a fundamental ethical dilemma: Who should get the vaccine first?"

Organ Donors After Circulatory Determination of Death
Increased use of donors after circulatory determination of death (DCDD) has been advocated as the most viable method for increasing the supply of transplantable organs. However, the number of potential DCDD in the United States remains uncertain, with estimates accruing from retrospective single-center experiences in adult or pediatric hospitals. A research team that included Scott Halpern conducted a prospective, population-based cohort study to estimate the potential increase in the supply of deceased donors that might accrue from optimal use of controlled DCDD, donors in whom life-sustaining therapies are withdrawn and organs are recovered following the loss of spontaneous circulation.

Principles for allocation of scarce medical interventions
Allocation of very scarce medical interventions such as organs and vaccines is a persistent ethical challenge. We evaluate eight simple allocation principles that can be classified into four categories: treating people equally, favouring the worst-off, maximising total benefits, and promoting and rewarding social usefulness. No single principle is sufficient to incorporate all morally relevant considerations and therefore individual principles must be combined into multiprinciple allocation systems. We evaluate three systems: the United Network for Organ Sharing points systems, quality-adjusted life-years, and disability-adjusted life-years. We recommend an alternative system—the complete lives system—which prioritises younger people who have not yet lived a complete life, and also incorporates prognosis, save the most lives, lottery, and instrumental value principles.

Regulated Payments for Living Kidney Donation: An Empirical Assessment of the Ethical Concerns
Scott Halpern has conducted empirical research on questions related to organ procurement. "Theoretical concerns about paying persons for living kidney donation are not corroborated by empirical evidence. A real-world test of regulated payments for kidney donation is needed to definitively show whether payment provides a viable and ethical method to increase the supply of kidneys available for transplantation...In this study, we did not aim to assess the conceptual strengths and weaknesses of these concerns, but rather we used empirical methods to determine the extent to which these concerns might manifest if a regulated market for kidneys were established in the United States."
