Transcript for How the COVID-19 vaccine will be shipped across the US
One of the most important missions U.S. Airlines have ever undertaken shipping them around the country. Cameras going behind the scenes at united airlines to see the extraordinary measures under way to make sure the vaccines get to the American people. Gio Benitez joins us from inside the united facility in Chicago. Good morning, gio. Reporter: United tells us in each plane they're going to be able to felt more T a million doses of vaccine but the challenge here is to keep them cold enough so take a look at this because we actually got a tour of that cold storage facility here in Chicago. United is going to be using this facility to sort the vaccines and they'll be transported in refrigerated shipping containers. If they have to be stored they'll be kept in even larger refrigerators. Now, this is an operation unl any other in American history and keep in mind right now we are inside a passenger plane, okay. The seats are just above us but when the vaccines are in here, this plane is going to be empty. There's not going to be any passengers on board to get these vaccines the country as soon as possible, Cecilia, if the fda gives them that green light. I was surprised to hear you were telling us that this is not the first time these airlines have transported medicines at this temperature. Reporter: Yeah, it's really incredible because united says that they do this all the time. They transport pharmaceuticals at ultra cold temperatures. Now, the difference here is the we are talking about millions of vaccines, so really the race is on to get more freezers here. Okay, thanks so much.
