For a while, says surgeon and public health expert Dr. Atul Gawande, India was on the same skyrocketing COVID-19 infection rate pathway as the United States. But then something remarkable happened: masking went way up, and infection rates plummeted. And in Israel, Dr. Gawande estimates that enough of the population has already been vaccinated to meaningfully bring down infection and hospitalization rates. The key to effective pandemic responses around the globe, Dr. Gawande concludes, is effective leadership. Dr. Gawande joins Ian Bremmer on GZERO World to talk about some of the success stories from around the world. He'll also weigh in on whether or not China and Russia's less-vetted vaccines are safe to take.
