liz: i'm going to go to gail smith, who is in charge of making sure those -- you have a tough job.he u.s. is committed to donating more vaccines than any other country on the planet combined. and she is responsible for getting them out the door. what i want for you to address is how hard this is because you and i have talked about the hurdles, but the logistic resources to get the vaccines. what is the administration doing to help ensure not only we are donating the vaccine but also -- this is so important -- i heard him speak on this. help us understand this. gayle: thank you. i appreciate everything that you do. this is hard but it's also doable. the way i like to describe it is it is ambitious. eating vaccines outdoor, there are a lot of legal and regulatory hoops. these are specialized medical tools. so, we have to be very careful and make sure we have safety and efficacy. but the real challenge -- liz: we can hear you. gayle: sorry about that. the real challenge is getting those shots in arms. we have to turn vaccines into vaccinations. this is a challenge in the united states
