Why the developing world is getting left behind on vaccine rollout

For the world's wealthiest nations, including the United States, the rollout of COVID-19 vaccine has been rocky, to say the least. And as a result, much of the developing world will have to wait even longer for their turn. Part of the challenge, World Bank President David Malpass says, is that "advanced economies have reserved a lot of the vaccine doses." Malpass sat down with Ian Bremmer recently to talk about what his organization is doing to try to keep millions around the world from slipping deeper into poverty during the pandemic. Their conversation was part of the latest episode of GZERO World.
