We're now one week into Joe Biden's presidency and the new administration is already putting into action its plans for the COVID-19 pandemic.

This includes the appointments of several key members of President Biden's new COVID-19 response team.

My colleague Anderson Cooper and I had the chance to talk to a few members of that team at a CNN town hall.

And today I've decided to share some of what they told us about the challenges that still lie ahead and their plans to bring this pandemic to an end.

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

Will we feel as if we have the herd immunity that everybody has been talking about by the end of the first 100 days?

I told you I'd tell you the truth. I don't think we're going to feel it then. I think we're still going to have after we vaccinate 100 million Americans, we're going to have 200 million more that we're going to need to vaccinate.

That's Dr. Rochelle Walensky. She's the new director of the Centers for Disease Control and Prevention, talking to Anderson Cooper and me on CNN last night.

We spoke at length with Dr. Walensky and also Dr. Anthony Fauci. He's the nation's leading infectious disease expert as you certainly know by now.

Also joining us was Dr. Marcella Nunez Smith, head of the new COVID-19 Health Equity Task Force at the Department of Health and Human Services.

Here's some of what we discussed about the Biden administration's plan to get this pandemic under control.

There are remain questions about the announcement yesterday that COVID vaccine allocations for states would increase by about 16% starting next week.

How is that going to be possible next week when it wasn't possible this week and where is the extra vaccine coming from?

Anderson, it isn't a question of extra vaccine coming from the flow of vaccine that has been coming in on what the person responsible for it.

General Gus Perna calls a cadence that's coming in. Right now we're having, and what the president was referring to is that a steady reliable flow will come in that he'd like to get them up to about 10 million per week.

It's right now somewhere I believe around 8.5 million. He wants to get it up to around 10.

And you can do that by efficiencies, by paying attention to anything that might get in the way of that and to try and get it smoothly into the flow.

So it isn't a question of getting vaccine that wasn't there before that's there now. It's an even flow which we believe we can accomplish.

Dr. Walensky, the latest numbers reported by the CDC say that in total more than 47 million vaccine doses have been distributed, but fewer than 25 million have been administered.

Are states holding onto vaccine to ensure that second dose?

So a couple of things with regard to the distribution and how much has been administered and then the holding on.

First of all, the distribution, those 47 million doses that you talk about. Some of those have just arrived today or yesterday.
