Dr. Jeremy Kamil is a virologist in the LSU system. He is one of the people I have encountered over the last year whose opinion I’ve learned to take to heart. Not because Jeremy holds forth from on high, but because he doesn’t. As you will hear in this conversation, he is candid about how little he truly knew at the beginning of 2020. A world transformed by COVID-19 has also seen a world of pundits and commentators rewriting history, testifying to their foresight. Masks are useless until they’re not.
