Sam Harris is an expert on neuroscience and meditation, not virology and immune response. He hosts the podcast and talks to relevant experts like Zeynep Tufekci on misinformation.
Nicholas Christakis is another good expert on the issue he interviewed. Sean Carroll is an cosmologist who also talks to various experts on many issues.
Sean and Sam are both far batter at judging the expertise of these people, and it's worth listening to the experts they spoke with. It's better than random people claiming expertise.
