, hosts Dominic Sisti and Steve Levine welcome Jason Schwartz, PhD, associate professor at the Yale School of Public Health, for a discussion on vaccine ethics, public health infrastructure, and the challenges of maintaining trust in immunization programs.

Together, they explore how the COVID-19 pandemic reshaped public attitudes toward vaccines, while also underscoring long-standing tensions between individual autonomy and collective responsibility. Schwartz, whose work focuses on vaccine policy and history, offers perspective on the systems and institutions, such as the CDC's Advisory Committee on Immunization Practices (ACIP), helping to translate scientific evidence into public health recommendations.

This episode comes at a time when ACIP is once again in the headlines as HHS Secretary Robert F. Kennedy Jr. recently 

replaced all 17 members with a new slate of individuals

, citing concerns about groupthink and conflicts of interest. The move has generated widespread commentary about the role and value of such expert advisory bodies in shaping public health decisions, especially in the face of growing skepticism and political scrutiny.

Ethical questions about equity, communication, and responsibility are threaded throughout the discussion. The hosts and Schwartz reflect on what it means to make fair vaccine recommendations in the context of incomplete data, and how institutions can maintain public trust amid scientific uncertainty. They also discuss how the infrastructure behind public health decisions—committees, advisory boards, and interagency coordination—can either strengthen or undermine confidence depending on how they function and how well they are understood.
