Vaccine Experts Say, "No Way" Trump Will Have Vaccine by November.
BALDWIN: President Trump is eager to have a coronavirus vaccine before the November election. In fact, he has publicly stated that he is, his word, "optimistic" there will be one by November 3rd. But CNN has obtained and reviewed a memo from Moderna -- that's a company currently in Phase II testing of a trial vaccine -- and it says it only has about 4,500 of the 30,000 recipients -- excuse me, participants needed to complete the trial. Infectious disease experts tell CNN that that means that there is no way there will be a vaccine by November. Elizabeth Cohen is our CNN senior medical correspondent. And you have seen that memo. So, you tell us why does Moderna believe November 3rd is unrealistic?</s>ELIZABETH COHEN, CNN SENIOR MEDICAL CORRESPONDENT: Well, actually, Brooke, it's not Moderna that says that. It's outside vaccinologists who I have been talking with. I said get a calculator. Get a calendar. If this is what we've done so far, will we have a vaccine by November 3rd? And they said, no way. That's an actual quote actually. No way. So, let's take a look at what Moderna has done so far. So, from that confidential email that CNN got a copy of, from July 27th until August 7th -- so that's two weeks' worth of work -- they got 4,536 participants enrolled and gave them their first shots. But they need 30,000. Now they expect that they can get shots into arms for 30,000 people sometime next month. But then they still have to give them a second dose 28 days later. So even if Moderna does ramp up its enrollment, which it's expected to do. These things start slowly and then get faster. Still if they are giving first shots in September, they are going to be giving second shots in October because there's 28 days. Then you have to wait two weeks for the vaccine to kick in because it's not immediate. And then you have to wait and send these people out into the world to see if they get coronavirus and then compare the vaccine group versus the placebo group. These things take time. And these doctors said, look, there is just no way --</s>BALDWIN: So, we're not even talking -- we're talking then, early next year?</s>COHEN: That's what these doctors think. They said that they think the first quarter of next year. Tony Fauci has said December of this year or January of next year. Both of those are after election day, that it just takes time basically for biology to work.</s>BALDWIN: We will try to be as patient as we possibly can. Meantime, Elizabeth Cohen, thank you so much. And I'm glad you're able to get your eyes on that memo for us. Meantime, in the last two weeks nearly 100,000 children have tested positive for COVID. Complicating the already complicated task of getting kids back in school. We have those details next.
