Three years after the start of the pandemic, former CDC Director Dr. Tom Frieden returns to reflect on what we got right and what we got wrong in our response to COVID-19. Andy gets the definitive answer to the question "do masks work?” Frieden also calls out one pharmaceutical company who could have helped save more lives and tells Andy what we need to do to prepare for the next pandemic. Plus, he shares one silent killer that isn’t getting enough attention and tells us what everyone can continue to do to protect themselves. Keep up with Andy on Post and Twitter and Post @ASlavitt.
