How does fear play into our understanding and awareness of CDC research? We take a walk back through moments of collective fear in history from atomic bombs to deadly diseases with Terry Pechacek, a professor of health management and policy at Georgia State University. Plus, we discuss one of the biggest contemporary threats to public health: antibiotic resistance. David Weiss of Emory University’s Vaccine Center explains what that is and why it’s a top concern for today’s health researchers.
