Transcript for Fauci on what to know about COVID-19 vaccine
We are joined by Dr. Anthony Fauci. Dr. Fauci, thanks for coming back again this morning. So we're seeing these first vaccines being administered as the country mourns more than 30lives lost, 17,000 the last week. How do you make sense of this moment? Well, you know, it's bittersweet, George, because we are still in a terrible situation with the numbers that you ment the deaths, the hospitalizations, the number of cases and yet we're really now starting to see the light at the end of the tunnel. That is going to ultimely get us through this. We know we're going to be able to put this behind us, but in the meantime, we still have a struggle ahead of us so we've got to get people vaccinated as quickly and as expeditiously as we possibly can until we get that herd immunity as we say which will require in my opinion about 75% to 80% of the population getting vaccinated but in the meantime, we have to adhere to the public health measures in order to blunt the acceleration of these terrible numbers that we hear every day. A know there's still a lot of skepticism about the vaccine. I was talking to a couple members of our crew. The basic question is how can we be sure it's safe when it was developed so quickly? You know, George, that's a great question. The speed was not at all at the sacrifice of safety. The speed was the reflection of extraordinary advances in the science of vaccine platform technology. To be able to do things technically in months that sometime ago, five, ten years ago may taken several in addition, the extraordinary investment -- when I say investment I'm talking hundreds of millions if not billions of dollars in getting the vaccine ready to be distributed as soon as it was proven to be safe and effective. So people understandably are skeptical about the speed, but we have to keep emphasizing speed means the science was extraordinary that got us here. President-Elect Biden has named you his chief medical adviser. You're still serving with the current administration. How do you straddle these two worlds and are we seeing the cooperation we need to see on production and distribution of the vaccine? Well, we can do both because the goal is the same, George. I mean, my goal as a physician, a scientist, a public health official, you know, we were very deeply involved and still are with the development of the vaccine, with the development of new drugs, with the policy about getting people out there like I'm speaking with you encouraging people to abide by the public health measures, that's not going to change. I mean, the thing is going to be the same. We still have a lot of problems out there. We still have a great challenge so I don't see any conflict at all. The Biden team says that President-Elect Biden will take the vaccine in public when you give him the green light. Should that happen right away? I believe so, George. I mean, this is a person who very soon will be the president of the United States. The president -- vice President-Elect kamala Harris will soon be the vice president of the united . For security reasons I really feel strongly we should get them vax namented as soon as we can and want him fully protected as he enters the presidency in January. That's my strong recommendation. What about president trump? He's already had the vaccine. Should he take the vaccine? I would recommend he do that as well as vice president pence. You still want to protect people who are very important to our country right now, even though prpresident himself was infected and he has likely antibodies that likely would be protective, we're not sure how long that protection lasts. So to be doubly sure I recommend that he get vaccinated as well as the vice president. Dr.auci, thanks for your time this morning. Good to be with you. A lot of important
