It’s becoming harder to get all Americans vaccinated. While millions of people still get the shots each week, some conservatives are becoming more difficult to convince, and some politicians are increasingly hostile towards the public health departments tasked with helping fight COVID-19.  Guests: Michelle Fiscus, former medical director for vaccine-preventable diseases and immunization programs at the Tennessee Department of Health, and Dan Diamond, health policy and politics reporter at The Washington Post.  If you enjoy this show, please consider signing up for Slate Plus.
