Fauci also faced a heavy dose of politics as Ohio Republican jim jordan pressed him over health risks of protests. I just want an answer to the question.

Overnight california surpassed half a million coronavirus cases, becoming the first state to do so. And there are nearly 4. 6 million cases now here in the u. S. With more than 154,000 deaths. We want to bring in dr. Ezekiel emanuel, a former Obama White HouseHealth Policy advisor now advising joe bidens president ial campaign. He is also the author of the book which country has the worlds best health care. Dr. Ezekiel emanuel. If we can quickly. Is the situation getting any better nationally, and what should those states that the white house identifies as being at risk, potential hot spots, they fear they could be the next california or florida, be doing right now . Well, we are progressing and we dont seem to be slowing down. We have 60,000, 70,000 cases every day. We have an increase in deaths. That is not a good we were having 30,000 cases. So we are actually doing worse. The states, they have to impose the Public Health measures. Social distancing, facemask wearing, hand hygiene and closing nonessential businesses, not having indoor businesses like bars, beauty salons, tattoo parlors and gyms. Thats what you have to do. We know this. We can see it from other countries that have been successful. They are bringing their cases not quite to zero, but very, very low. Dr. Emanuel, lets talk about the other big issue, which is testing. We are doing more testing now, nearly 1 million tests per day, but a lot of the results are not coming in fast enough. People having to wait days or even longer than a week to get those results. Everyone, even the president , says we need to do better on this. So what specifically needs to happen in order for there to be more quick tests all across the country . You need competent leadership and coordination. The president gave this to Jared Kushner and admiral jugirar in midmarch. Five months later, we still dont have adequate testing. That is incompetence. You need a supply chain. You need to tell the Testing Companies they need to beef up their activities. They wanted these tests. They are getting paid handsomely, 100 a test. If they cant give results in 48 hours, maybe we shouldnt pay for them. That idea has been suggested by a group from duke, and i think its quite reasonable. If the test isnt medically useful, why are we paying so much money for it . We also need to accelerate the development of those home testing kits, point of care testing kits. All of this should have been, and, you know, Jared Kushner and admiral girar have not stepped up to the job. This is not very good leadership. Doctor, can you give us a reality check on vaccines right now . Obviously, there is a reason for optimism. We know that trials are progressing, hope that there may be progress before the end of this calendar year, but how much stock should we be putting in a vaccine sort of putting an end to this, and what challenges still lie ahead on that . We have six vaccines in whats called phase 3 trials, the effectiveness, the final phase trials. I think dr. Fauci is right, by early next year we will have important results, whether they work or not, and which ones of them work. There are two big issues once you have a vaccine proven. One is how long is it good for. A vaccine that lasts only three months is not very effective. We need one that really lasts at least a year. And then there is the big challenge of actually going from producing the vaccine to putting shots in arms of 300 million americans and some of these vaccines require two doses which require 600 million shots inside of a couple of months. I dont think thats logistically possible. Again, this administration has not shown itself capable of managing these kinds of complex issues. They just dont have the competence to do it. And there are many, many barriers potentially. Glass vials to put the drugs in. You need actually to fill them and put them in the glass vials in super sterile conditions, ship them out and get people to vaccinate. Imagine 300 million vaccines. You need one Million People working almost a whole month. You know, its a very, very big challenge. Well, the whole country is united on one thing, hopping they get that vaccine soon. Thank you for waking up with us on a saturday. Thank you. Good to be here. We appreciate it. We have much more to get to this morning, including questions about the future of the popular videosharing app tiktok. A source confirms to nbc news that microsoft is in talks to purchase it from its chinese owner. Tiktok has 100 million users in the United States but President Trump is not one of them. The president told reporters friday night he wants to ban tiktok using an executive order as early as today. In a statement, tiktok said its data is stored in the u. S. And the company is committed to protecting users privacy and safety.
