 Practically speaking what do you think needs to happen to see that global rollout become a reality? In 2020 the world did come together, coordinated through the World Health Organization. It brought together many of the world's governments, it brought together many of the world's philanthropy and it brought together many of the world's industry and agencies. It's there in order to make sure that the scientific advances of 2020 are now made available and benefit the whole world in an equitable way that brings the pandemic to an end and allows economies to get growing again. And it is that combination of the world coming together under the auspices of WHO in order to make fair inequitable access that brings the pandemic to a close that will allow education to go back, it'll allow economies to regrow and of course it will protect people's lives.
