Vaccine the Rest of the World

We want to prevent new variants from developing elsewhere and then coming here. And that's why that we are accelerating our work on the global front. In addition to donating already and delivering over a hundred and 20 million doses of vaccine to other countries, we are moving on the half billion doses that we have purchased from viser for the rest of the world. We don't have a choice. We have to protect americans. A, it's what we need to you to stay safe. T last question. Can you talk about why the initial data wasn't compelling back in july?
