We've been talking a lot about vaccines this past year and now they are poised to become a reality.

The Pfizer vaccine was authorized in the United Kingdom last week and people are now expected to start getting shots this week.

Here in the United States there are two vaccines from Pfizer and Moderna that are currently under FDA review for emergency use authorization.

I know you have a lot of questions. I certainly have a lot of questions myself. When can I get it?

What are the side effects? Is it safe? So to answer all these questions, Anderson Cooper and I hosted a town hall last week.

I'm Dr. Sanjay Gupta, CNN's Chief Medical Correspondent and this is coronavirus, fact versus fiction.

Hey welcome, I'm Anderson Cooper.

And I'm Dr. Sanjay Gupta. This is our 23rd CNN Global Town Hall on the coronavirus. Only this time the title is a hopeful one, the vaccines.

Dr. Anastasia Fouchi, Director of the National Institute of Allergy and Efectious Diseases. He's also soon to be a Chief Medical Advisor in the incoming Biden Administration.

He's of course still a member of the White House Coronavirus Task Force. So Dr. Fouchi, President of Biden is saying there is no detailed plan from the Trump Administration about distributing a vaccine.

Have you seen a plan? What's going on?

Well, there clearly is an organized approach that's right from the military component of Operation Warp Speed, the planes, the trucks, the trains that take the material, in this case the candidate vaccines, from the storehouses, the warehouses where they are, after they've been filled and finished, for the local places of distribution.

Namely the state and the city, local areas. Once it gets there, Anderson, it is up to the state and local authorities in their individual way to make the decisions about the distribution as well as the logistics of it.

So it really is going to be at the level of the state. So I think that's what is meant by not having a broader global in the sense of the whole country plan, but the individual states and localities will make their decisions and the individual states.

And the distribution, the way they normally would distribute something like influenza vaccine. So that's really the way it's going to be.

I wonder if you could give us a picture of what it's going to look like. I mean, where will most of the vaccines actually be administered, do you think, through doctors offices, hospitals, CVS and Walgreens type locations?

Yeah, Sanjay, it's going to be all of the above. So it's going to be CVS, Walgreens, doctors offices, clinics and hospitals. I know that because they're already been shipped, ready for distribution.

And you know, like you would do, Sanjay, I've made a couple of calls around right here where I live in Washington. And already we know there are some hospitals, some clinics that already have material that has been shipped to them.

So when you said hospital, some hospitals already have it, when do they get the go ahead to start, you know, inoculating people?

Yeah, as soon as the EUA is officially administered by the FDA, right, the emergency use authorization, essentially immediately after that, it likely will be a day or at the most a couple of days.

But it is essentially right from the time that you get the official authorization by the emergency use authorization, what we refer to as an EUA.

You recently apologized for criticism of the UK speedy authorization of the Pfizer vaccine. Can you just talk about your initial concerns about that and the speed at which this is happening?
