In the fall of 2019, weeks before the COVID-19 pandemic would change the world, Ian Bremmer asked Dr. Fauci what kept him up at night and he described a "a pandemic-like respiratory infection." Fast-forward to late February 2021 and Dr. Fauci tells Ian, "I think we are living through much of that worst nightmare." Dr. Fauci returns to GZERO World to take stock of the nightmare year and to paint a picture of what the end of the pandemic could look like—and when it could finally arrive.
