Community Immunity is an audio extension of a Substack newsletter focused on vaccines and public health. Hosted by pediatrician and public health physician Dr. David Higgins, MD. The podcast offers clear, evidence-based analysis of vaccine science, policy, and communication — with attention to how decisions made at the federal and state level play out in clinics and communities. Episodes are audio versions of written posts, shared for listeners who prefer to listen rather than read.
