A few decades ago, nobody really questioned vaccines. They were viewed as a standard part of staying healthy and safe. Today, the number of people questioning vaccines risks prolonging a pandemic that has already killed hundreds of thousands of Americans. How we got to this moment didn’t start with the rollout of vaccines or in March 2020, or even with the election of Donald Trump. Our confidence in vaccines, often isn't even about vaccines. It’s about trust. And that trust has been eroding for a long time. Doubt, a new series from Bloomberg’s Prognosis podcast, looks at the forces that have been breaking down that trust. We'll trace the rise of vaccine skepticism in America to show how we got here — and where we’re going. Doubt launches on March 23.
