our senior medical correspondent elizabeth cohen joins us live. in these studies and who can't? >> poppy, let's take a look at this. there are four trials that are expected to start over the next couple of months. they will need tens of thousands of volunteers in various locations across the country. let's look, the url, the website you can go to is coronavirus prevention network.org. book mark that because i know i wouldn't remember it. ages 18 and over are eligible. they are looking for people at the highest risk of getting sick from covid-19. and here's the reason. if you vaccinate a bunch of people who stay at home all the time, well, they won't have the chance to get the virus so you don't know if the vaccine is working so they have a preference for people who are out and about more where coronavirus is prevalent. poppy? >> okay, elizabeth cohen, thank you very much. >>> i'm joined now by andy slavitt from the centers for medicare and medicaid services under the obama administration and dr. ross goldberg, president of the arizona medical asso

but i -- i feel so proud. >> elizabeth cohen joins us now.zabeth, phase three, obviously, it's a big step. how much confidence is there that this will work? >> as dr. fauci said, he and others are cautiously optimistic. that's because, anderson, they've already tried this vaccine out, in dozens of people in earlier trials. and what they found was they got a good immune response. they looked at the patient's blood. it looked good. they were good antibodies that, theoretically, and i stress the word theoretically, should fight off covid-19. but now, this is the real world. they are going to vaccinate these people. put them out into the world. and see if it works. this, anderson, is the real test. >> elizabeth cohen, thanks very much. just ahead, a friend and colleague of civil rights icon and congressman john lewis joins us. james clyburn on the legacy of lewis and president trump's refusal to visit to pay respects to him at the capitol today. thinking about your financial plan... ...so are we. prudential helps 25 million people with their fina

let's go straight to elizabeth cohen to give us the details on this. she's in savannah, georgia, where this moderna trial is going on elizabeth? >> reporter: john, this is truly a historic moment. we watched as the first patient in the united states got a shot as part of a phase iii clinical trial for a covid vaccine. this is really amazing. i mean, we didn't start working on this vaccine until january, so just seven months later, to have someone getting a shot in a phase iii trial is truly remarkable. of course, everyone's fingers are crossed. we hope that this leads to a vaccine. but that's why we're doing the clinical trial. there's a possibility this might not work. of course, everyone hopes that it does. they will eventually be giving shots to 30,000 people for this moderna vaccine. half of them will get the actual vaccine, half of them will get a placebo that really does nothing. and in the end, they'll see what happens to those two groups. is there any difference? they hope there is a difference, and that the vaccine protects people from getting

brennan and cnn correspondent elizabeth cohen. elizabeth, a new record was hit yesterday. how dangerous is that situation heading into a holiday weekend? one expert is even calling this a perfect storm for transmission. >> right, jim. we saw what happened during memorial day, was in the weeks after that the numbers went up. there is no reason to expect anything different from july 4th unless people behave differently. but there really isn't an indication that that is the case as people get together, whether it's a group in someone's home, or a large group at a larger gathering, that is a problem. i have been saying this from the beginning, that you do not need a phd in immunology to know that these numbers grow when people get together and they stop when people are apart. >> the surgeon general warns today that the death toll lags behind rising cases. we saw that at the beginning of the pandemic in the u.s. what could we be seeing in the next few weeks? are we going to see the death count go dramatically up in the u.s.? >> hi, jim, thanks for having me. this is a hard time

i want to bring in elizabeth cohen who sat down with medical correspondent sanjay gupta.everyone wants to know is when will the vaccine roll out? is it definitely a when and not if? >> you never know. we're trying different vaccines. it's possible none of them will work. there's hope one of them will. there's been a lot of talk about getting shots into arms this year but the doctor told me for months americans it's going to be next year and even well into next year. >> when do you think i will be able to get a covid vaccine, walk into the doctor's office, walk into a pharmacy. >> we're working hard to have vaccines tested appropriately, manufactured appropriately, assessed and approved independently by fda and available for use in the population by the end of this year or early next year. we will not have it for the u.s. population on day one. we'll probably have a few tens of millions of doses in december and january and probably it will be appropriate to immunize those individuals at highest risk for the covid virus. i am optimistic that we have vaccines for everybody i

cnn senior medical correspondent elizabeth cohen joins me now.ld health organization says 19 candidate vaccines in clinical evaluation around the world right now. how likely we'll have more than one available, one that works, by 2021? by early next year? >> certainly, jake. we have been told by tony fauci and others that they hope, they think that we will have a vaccine by end of this year or early next year, but you never quite know. i mean it is important to state here that nobody has a crystal ball. nobody knows for sure. they're certainly hoping that that's the case, but we haven't even started phase three clinical trials in this country. so how do we know that that's going to happen? it's very difficult. now, i did talk to dr. fauci last week, and i said, you know, china may be ahead of us here. they are moving into phase three trials and how would you feel if china got it first? he said, i would say, "god bless." i don't care who gets it first. i just want to us have a vaccine. several countries are working on vaccines. the hope, someone wi

let's bring in cnn senior medical correspondent elizabeth cohen and you always do this caution. this is early data, but what are we learning from it? >> right, jim. absolutely. i'm going to issue that caveat right now. this is early data. this is a very small group of people. it's about 36 study subjects and you don't know what's going to happen when this is done in real world circumstances, but they did get an immune response that seems to be impressive according to outside experts that i'm talking to. it was especially strong when they gave two doses of the vaccine. there is a however here. actually, there are several howevers. i'll give you the first one first which is a -- there were many people with fevers when they were given this. even at a low dose one out of 12 study subjects got a high fever. half of the people got a fever after one dose and those fever numbers went up. those fevers are trance yept. they go away in about a day according to this study. that's a good thing and you could make the argument, well, you know, a day of fever is a small price to pay for a vacci

elizabeth cohen is here to explain what this means. elizabeth, good morning. what does this tell us that they're moving now into phase three? >> this is really exciting news. there is so much hope for these kinds of drugs. they're a little bit a cross between a treatment and a vaccine. they take antibodies that fight off the disease, and instead of making a vaccine along the theory, they use it as a drug, take the best antibodies so that you can give it to patients. let's take a look at the clinical trials that they're moving into, erica. it's basically in three different groups. they're going to try out their drug in patients who are hospitalized with covid-19, patients who are at home with covid-19, so not as ill obviously, and also as a prevention for people living in a house with someone with covid-19 who are at high risk of getting it and if you add all of those up it's 4,900 patients who are going to be involved in these clinical trials. these trials typically take months. they are not quick, but it is quicker than getting a vaccine. erica? >> we'll keep

i wouldn't be surprised if it's in the 90%. >> elizabeth cohen joins me now.viously that is way more optimistic than many experts are, even those who are relatively optimistic. how does he back it up? >> reporter: you know, he just said that based on the biology of this virus, that when you look at how it works, he thinks it can be that effective. it's not so pie in the sky. chickenpox, measles, polio, those are all vaccines that are in the 90s. so it's possible this one is, too. he headed up the development of five major novel vaccines. so let's hope he's right about this one. >> elizabeth, when you look at that, you also have this new study out today in the journal "nature" which i mentioned earlier with nick watt, with people who never had covid possibly having immunity to the virus. is that possible or just picking up people who have had a common cold, which is a coronavirus, but doesn't mean anything about immunity, what do you know? >> you know, it's really unclear what this means, erin. but it is intriguing. so what these researchers found is about 35%

cnn's senior medical constituent elizabeth cohen joins us now. and this new study from the journal of the american medical association specifically looks at deaths between march and may. why were so many deaths unaccounted for and by how much? >> let's take a look at what the study authors did and retrace steps here, jake. what they did is they looked at deaths between march and may this year and compared it to previous years. they found there were 122,300 more beths in that time period than there previous years. the study authors believe the majority of the deaths are attributable directly or indirectly to covid. but when you look at the death count it is only 95,235 deaths so the study authors believe that is an underestimate. they say look we have this many excess deaths from this year kbhared to last year and we believe it is attributable to covid so they believe the 95,000 number is really low. jake. >> elizabeth cohen, thank you so much. >>> in california, a record breaking new kroerp cases, 9,740, the high number since the pandemic started

joining me now is cnn senior medical correspondent elizabeth cohen. so a more easily transmissible coronavirus. what does that mean for the country right now? >> you know, we apparently have been seeing this mutated form for it. i want to talk about mutation because i think that scares people. not all mutations are created equal. this mutation doesn't get you sicker. it doesn't mean you'll be more likely to die if you get infected. what it does it makes the virus more transmissible, more contagious. this is the reality we're dealing with. i mean, we can see from the state numbers how quickly this virus is spreading. this could mean for the vaccine that you will need to get -- that we will all need to get a booster. dr. frances collins at a hearing addressed this. he's the head of the national institutes of health and he said it could mean that we need to get a booster because we treat the vaccine, we come up with a better one. that wouldn't be such a big problem. if that's the only thing that this mutation does. that would be great. and according to t

cnn's senior medical correspondent elizabeth cohen joins us live from savannah, georgia, where the very first patient was vaccinated this morning. explain to us how this trial could work and how soon we know this vaccine is effective. >> 30,000 people will be vaccinated in the united states. the first one was here in savannah, georgia, as you mentioned. and what they're going to do is 15,000 people will get the actual vaccine that's been made by moderna. and 15,000 people will get a placebo. and then they will be followed to see who fares better than hopefully the vaccine group will fare better than the placebo group. i got to speak with don baker, she was the first person in the u.s. to receive an injection in this trial in the phase three trial. let's take a listen to her thoughts. >> now, you don't know if you got the vaccine or the placebo. but either way you're helping to find a cure. >> either way it's a really important role to have and to be a part of that research. >> you are the first person in the united states to get a shot in a phase three covid trial. what does that feel l

cnn medical correspondent elizabeth cohen joins me now. i believe dr.fauci in an interview with you talked about aiming for 75% effectiveness here. is 50% above a placebo, is that a standard level for judging the effectiveness of a vaccine or is it being lowered given the outbreak? >> no, you can see -- you can see me shaking he head no, that's not the standard. dr. fauci said he'd settle for 70 or 75% effective, and it appears that the fda would settle for 50% effective. you're absolutely right. that is not a very high number. if we get a vaccine that's 50% effective and we know from polling that about a third of americans say they don't want to get it, that's not going to go well. a vaccine that's 50% effective being given to only 70% of the population will that help, sure. it's better than nothing. is that great, absolutely not. look at measles, measles is 97 to 98% effective. the vaccine for measles. the vaccine for chickenpox and polio, those are more than 50% effective. i did speak with the expert who is involve in this, he said it will be better

elizabeth cohen and dr. celine gounder. we are back with alberto carvalho, the superintendent of miami-dade county schools and factors large in what we hear from the governor there. elizabeth, something that we heard the governor say, he was talking about particularly at a place like jackson i think he said where they have folks come in -- health system, they have folks come in for things unrelated to covid and get into a car accident, heart problems, everybody is swabbed and tested for covid. i think the rate of 30% to 40% is positive, they're incidental covid positive in the hospital. that stood out to you. tell us. >> i think that's a stunning number. in a way, a closest we get to a surveillance number. how many people in the community have covid? you can't test everyone but coming into the hospital you can so they're coming in after a car zoent or after a heart attack and 30% to 40% of them have covid? that's a very high number so when you hear that number juxtaposed to the decision to require that schools reopen when sc

cnn's senior medical correspondent elizabeth cohen joins us live in savannah, georgia, where that phase three vaccine trial has just begun this morning. so tell us what you saw on the ground there, elizabeth. >> today is truly a historic day. the first person in the u.s. to get a shot in a phase three coronavirus vaccine clinical trial, and i met her. her name is dawn baker. she's actually a local anchor, a news anchor here in savannah. i talked to her after she got that first historic shot. now, you don't know if you got the vaccine or the placebo, but either way you're helping to find a cure. >> either way it's a really important role to have and to be a part of that research. i never thought i'd do something like this. >> you are the first person in the united states to get a shot in a phase three covid trial. what does that feel like? >> it is very exciting. i'm very anxious about it. i just hope that there are really, really good results. i know a lot of people are doing a lot of different vaccine trials and things are going on, but i feel so proud. >> now, you'll notice that i ask

. >> and our own elizabeth cohen has just spoken with the boss of operation warp speed. that's the white house's vaccine program. he is bullish. he's confident. he said, yeah, maybe we'd need to have boosters of the vaccine. he said that based on his experience he thinks a covid-19 vaccine will be 90% effective. that's pretty good. >> that would be excellent if it happens. let's hope it does. nick watt in los angeles. let's get more. william hazeltine, chairman of access health international. also with us former u.s. surgeon general, also by the way advising the biden campaign. doctor, what do you make of this head of operation warp speed elizabeth cohen speaking moments ago that he expects the vaccine, once it's ready, to be 90% effective? >> wolf, i certainly hope that's the case. the more effective the vaccine is, not only will it help more people but fewer people will need to vaccinate in the end to achieve herd immunity levels which require about 70% of the population be immune. here is the truth, we can't bank on that. we have to wait for the data to come in to see

. >>> well, cnn senior medical correspondent elizabeth cohen joins me live. what do you make of this, elizabeth? >> you know, when president trump contradicts dr. fauci, which he has done over the past few months, i think to myself, we all have a choice. we can believe what an actual doctor, an infectious disease expert, someone who has served his country for decades, many, many presidents helped get us through hiv, helped get us through h1n1, swine flu. or we can believe president trump. we have a choice. president trump has been what one expert referred to me as the most anti-science president perhaps ever. we get a choice about who we're going to believe. >> i think that's a fair way to put it. and clearly the president is not happy with dr. fauci saying, look, guys, we're still knee deep in this pandemic. you can't get complacent. that is not the message the president wants to be out there from his health officials. but if it's the reality, it's the reality. so we'll continue to watch that unfold. meantime, we are following these new questions about whethe

let's get the latest from senior medical correspondent, elizabeth cohen. what is this, elizabeth? >> reporter: alisyn, good morning. the white house describes contact tracing as a core state preparedness responsibility. the cdc says it can effectively break the chain of transmission. you find the cases, you ask who they've been in contact with while contagious, and then you tell those people they need to quarantine. so we looked at florida, which is of course now the nation's number one hot spot. and here's what we found. we talked to more than two dozen people who had covid, 27, to be exact. we found that only five of them had received contact tracing phone calls from florida state health authorities. only five of them. now, the -- part of the problem is that florida should have more contact tracers. if you compare them to the standard of the national association of county and city health officials, they are missing thousands of contact tracers. they're not alone. only seven state have enough contact tracers when you look at the standard set by that group. but the problem is that

cnn's elizabeth cohen is live in savannah, georgia, with the details. tell us about this breaking news. >> reporter: you know, this is just another vaccine, one more to add to the list that operation warp speed is funding, and many of them are being funded to the tune of billions of dollars. let's take a look, alisyn, at the entire list. so there are two that are already in phase three trials. that's the final round of trials before hopefully review of data and approval. that's moderna and pfizer. affidav astrazeneca, johnson & johnson also getting funding. they're expected to begin phase three by september. this one we just learned from, glaxosmithkline, they say they will be in phase three by the end of 2020. there's also two more unnamed vaccines. i had an exclusive interview yesterday and he said eight total. i you add that up, that adds up to eight. i asked the doctor when do you expect most americans will be able to get a vaccine. i think this is very important because everyone keeps hearing, oh, by the end of the year. that's not quite right. wha

cnn's elizabeth cohen spoke with the company's ceo and joins us now with the breaking details. ohn, good morning. this is a $1.6 billion -- that's billion with a "b" -- contract to novavax, the largest of any of the contracts that operation warp speed or the government have done for a covid-19 vaccine. now, they think they could have this vaccine -- novavax thinks it could have this vaccine on the market by the first quarter of next year, if all goes well. now, they're currently doing preliminary trials in just 131 patients. they need to move on to large, phase three clinical trials of 30,000 people. i sat down with the ceo of novavax, stanley urk, and asked him, when would you be starting these phase three trials? when do you expect to begin your large-scale phase three trials? >> i think in the fourth quarter. we don't have a date set yet, but hopefully, as early in the fourth quarter as possible. maybe, if we're lucky, we could start phase three in late third quarter. >> reporter: now, there are three other companies that have gotten money from the federal government. the fir

let's go to senior correspondent elizabeth cohen. you're getting new information. what are you learning? >> reporter: the federal government's multibillion dollar effort to develop covid-19 vaccines. and i asked him, you know, vaccines, different vaccines zrircht level of efficacy. how effective do you think a covid-19 vaccine will be? let's take a listen to his answer. >> some vaccines are 97% effective. others are 60% effective. where do you think we're going to fall with the covid vaccine sf. >> i think this vaccine is going to be highly efficacious. i wouldn't be surprised if it's in the 90%. i think the question that's open is for how long will the vaccine afford efficacy. this is something that we will learn as we go. it's possible we will need to have a booster, a recall immunization every year or two years or every three years. >> now, i also asked the doctor about the time line for the vaccine and he did it sort of in stages. he said that he expects by december of this year or january of next to have tens of millions of doses for high risk americans, in ot

survey suggests a high rate of infections without sin tends led speaks to our india correspondent elizabeth cohen in new delhi for is so is this survey done in mumbai only confirms what many people have suspected and that is the number of cases is much higher than what's being reported by the government. faulty the results are very much a reflection of what independent health experts have been saying for a long time now which is that because india is still not conducting enough tests it has on the been lowest. testing in the wote that the rail number of infections of india are at least 10 times the reported number and possibly even up to 40 times you mentioned what's known as asia's largest dot of a well that has confirmed it's confirmed cases around 2 and a half 1000 but the syrian article survey shows that nearly 60 percent of people who live in slum slums of shanties have been infected so the real number of cases and thought of it is more likely to be around a 1000000 outside of these densely populated slum areas the percentage of people who have the virus is around 16 percent while the offici

. >> let's bring in our senior medical correspondent elizabeth cohen. good morning, elizabeth. you sat down with the first person to receive phase three covid vaccine injection. what did she say? >> right. she's the first person in the united states. her name is dawn baker. and we were there when she got this shot. it was really an historic moment for the medical crew working there, broke out into applause after she got that jab. they will eventually give shots to 30,000 people in the moderna phase three clinical trial. about half will get the actual vaccine. the other half will get a placebo, basically a shot that does nothing, and then they will follow them to see who fares better. i got to sit down with dawn right after she got her shot. now, you don't know if you got the vaccine or placebo, but either way you're hoping to find a cure. >> either way it's a really important role to have to be a private researcher. i never thought i would do something like this. >> you are the first person in the united states to get a shot in a phase three covid trial. what does that feel lik

it could potentially treat patients already infected and elizabeth cohen is following this. about this potential treatment. >> when one of us, someone gets infected with coronavirus you produce antibodies and not all of them are created equal and what companies are trying to do is identify the most powerful, clone those and turn these into a drug and so regeneron is starting phase three trials with three different approaches. the first approach is as a treatment for patients who are so sick they're in the hospital, a treatment for patients not so sick at home and also a prevention for people who are living at home with someone who has coronavirus so therefore they're at high risk and taking the drug help stave off the infection altogether? now, when you look at the three different groups that's 4,900 study subjects, high hopes that this antibody approach whether by regeneron or someone else will yield results and hopefully a bridge to a vaccine because the clinical trials should be quicker than the trials for a vaccine. >> that is interesting. there's also a new aspect of how

senior medical correspond department elizabeth cohen spoke with him at a clinical trial site in savannah, georgia. >> reporter: laura, boris, i sat down for an exclusive interview with the head of operation warp speed, the multi-billion dollar effort to develop a covid-19 vaccine. what he told me is that he thinks this vaccine is going to be very effective. >> it's very hard to predict, of course, that's why we're doing the trial. my personal opinion based on my experience and the biology of this virus, i think this vaccine is going to be highly efficacious. i wouldn't be surprised if it's in the 90%. >> reporter: some experts have lower expectations for the efficacy. he went over with me a time line for what he expects to happen. he expects by december of this year or january of next that we could have tens of millions of doses of covid-19 vaccine and he said those would go to high risk individuals, for example, the elderly or people with underlying medical conditions. he said that by the end of 2021, he expect there to be enough vaccine for all-americans although ideally he hopes to ha

let's bring in cnn senior medical correspondent elizabeth cohen to help us work out of this cloud that we are in. what's going on, elizabeth? >> i'm not sure i can help you because this is so confusing. they're talking about guidelines, reference documents, no, not a reference document but a guideline. who cares? what the american public is looking for, what schools are looking for is some clarify and in an almost -- it is almost if it's not so sad it would be funny and almost funny way providing a lack of clarity using the ridiculous bureaucratic words. what schools need is guidance. what do we do about the student that has asthma? many do. what about the teacher with diabetes? how in the world do you keep children six feet apart? even if you keep the desks six feet apart, what do you do when they have to go to the -- when they leave school or in the hallways? when my daughter has a playdate i couldn't keep them six feet apart if i tried. how do you keep a classroom of children six feet apart? these are the answers we need and not a debate of reference documents versus guidelines vers

senior medical correspondent elizabeth cohen is here. this is something we've always focused on.any people are out there, spreading this without knowing. tell us what it means, this half number. >> right, brianna. when you look at this study from yale, it really does speak sort of very closely to this issue. let's take a look at these numbers. what they found is that between 47 to 48% of spread is done by people who are presymptomatic. in other words, they will feel si sick, but they have not yet felt sick. this is something that is sort of unusual to covid. usually people aren't all that contagious before they're actively ill. with covid, they are, which is one of the things that makes this virus so hard to bring under control. as far as asymptomatic patients, 3.4 to 6.6% of the spread of covid is from people who don't have any symptoms at all. this 47 to 48% number, brianna, when history is written, that is the line of why this has been so tough. it took, at least in the united states, quite a while to accept that that much transmission could be done before people are actively

let's go to elizabeth cohen. they'd lose the money if they didn't work, but how sure are they that this one works? >> you know, there's a lot of cautious optimism. i think that's sort of the watch word of the day. cautious optimism that one or hopefully more of these vaccines will work. but hopefully, you know, we need to keep studying them. novavax has only studied this in 131 patients. they need to move into phase three clinical trials. i asked the ceo of novavax, let's take a listen to his answer. >> i think in the fourth quarter. we don't have a date set yet, but hopefully as early as the fourth quarter as possible. maybe if we're lucky we can start phase three in late third quarter. >> now, novavax is one of four companies that are getting big money from the federal government to do the phase three trials and several have said they hope to get the vaccine on the market end of this year, beginning of next year. poppy? >> thank you, elizabeth, on that. >>> the government nearly giving nearly half a billion dol

cnn's medical correspondent elizabeth cohen is with us now. so what could this mean and what does this drug do? >> so, anti-cook tills is a drug for which there's a lot of enthusiasm, that people hope that they will be a bridge to a vaccine since this will take us a while to get to a vaccine. what they do is look at antibodies developed after infection and cull the best and strongest once and put them together into one drug. let's take a look at three different groups of people involved in the large-scale clinical trials. first you have people so sick in the hospital with coronavirus. secondly people who are less sick but at home recovering from coronavirus and then thirdly prevention. those first two are treatment and they are also looking at prevention. give it to someone who lives in someone with coronavirus, they are at high risk for getting it. will this drug prevent this person from getting infected with covid? >> now it will take, you know, months to do the clinical trials but it is expected to be faster than doing a clinical trial for

to elizabeth cohen. the president and dr. fauci both at an impasse. we know what the polling says, but it's a big problem when you don't have them on the same page with major health implications. >> absolutely. we get to decide who we'll listen to. the president or someone with many decades of infectious disease experience. let's take a listen to what president trump said yesterday about dr. fauci. >> i disagree with him. you know, dr. fauci said don't wear a mask and now he says wear them. he said numerous things. >> like many things that the president says there's a small grain of truth but overall it is just wrong. he didn't -- dr. fauci didn't contradict himself on masks. back in february and early march he said, look, there aren't enough masks out there for people who are health care workers, for people who are truly ill. that is a problem so we're asking others not to wear a mask and then he said as time went on, he will look at this. the outbreak got much worse, the supply of masks got much better and now he's saying, yes, wear a mask. so he's

. >>> i'm elizabeth cohen, the pharmaceutical company gilead is doing a new clinical trial of remdesivir. remdesivir is the drug the only drug that's been approved for covid-19 but it's currently only used in hospitalized patients because it only comes in the intravenous form. gilead is going to try it in the inhaled form and then it can be used by patients at home. >>> i'm jacqueline howard in atlanta. the pandemic is hitting nursing homes particularly hard. experts say better funding and more specialists on the ground are needed to slow the spread of covid. not all nursing homes have the money in the budget for more protective equipment for the caretakers. that can help prevent the spread of the disease and not all have funds for testing. testing helps track who is sick and the u.s. about a quarter of all covid deaths come from nursing homes. >>> so we just spoke about this president trump threatening to defund public schools if they do not reopen this fall. but what about those cities and states that are seeing this sharp rise in cases right now? the head of miami-dade public schools

cnn's elizabeth cohen is tracking this information that's coming in. what is pfizer reporting in and how much stock are folks putting this early data? >> kate, i think that people should be very careful about this early data because one, it's in a very small number of people. two, it was not published in a medical journal and pfizer put it out on the internet. they posted their study and for all of those reasons as well as many others, we should be very careful. it doesn't mean these people were protected against covid. it just means they saw certain immune logical markers in their blood. what pfizer did was they vaccinated 36, and on average they did receive an immune response ask that immune response was best after two doses. now here's another reason why we should be careful. they gave doses of varying sizes and after two medium-sized dozes, 70% experienced fever and others had had theache or fatigue. it was transient, the fever went away within a day, but still that's something you want to keep an eye on. you can make an argument and you can buy th

. >> reporter: elizabeth cohen, cnn, savannah, georgia. >>> well, with less than 100 days until the election, the u.s. president insists his own polling shows him ahead in swing states. the most public polls show donald trump trailing or tying with presumptive democratic nominee joe biden. a new nbc marist poll in the battleground state of north carolina has biden up 7 points. the president's handling of the pandemic is costing him support with more people trusting biden when it comes to the coronavirus. >> so here to talk more about this is larry sabato. he's the director of politics at the university of virginia. good to have you with us. >> thank you so much. >> so, larry, 98 days to election day and state and national polls show donald trump trailing his democratic national rival joe biden. we have learned not to trust polls so how much comfort should the democrats take from these numbers and where do you see all of this going? >> over confidence can kill so actually democrats are better off not focusing on the polls. the polling actually is more accurate this season than it was four yea

senior medical correspondent elizabeth cohen is here. know, i think people understand that this is airborne. right? this is why there's social distancing. perhaps it is a matter of how airborne it is and just getting the clear guidance on this. why is the w.h.o. reluctant to talk about this, elizabeth? >> you know, brianna, airborne is a very loaded word. public health people get very nervous about this word because it sounds -- they're afraid it sounds hysterical. if you look at the w.h.o. or the cdc website they really emphasize that droplets that you can see, if you sneeze or cough or sometimes when you talk you can see the droplets and they emphasize that so you need to be relatively near someone to get hit by a droplet and those droplets are heavy and fall and don't talk about little droplet that is float along in the air to get there just by breathing so not the big, wet droplet that is fall but little ones that stay in the air and someone can leave a space and then you can walk into it a while later and you can run into those litt

elizabeth cohen, and what is the president getting so wrong here?ow, brooke, like many things that the president said there is a kernel of truth but the thing is wrong. yes, the number of deaths has come way down from april until now. but there are several reasons for that. one of the reasons is that this surge that we're seeing now in florida and texas and other hot spots, it is pretty new. it is only a few weeks old. it takes a while to go from infection to being sick to dying to having that death recorded. that takes about a month. and so we're not seeing those deaths now. but unfortunately in the coming weeks we will see those deaths. and that is one of the reasons why tony fauci said don't get too confident about the lower death numbers. >> it is a false narrative to take comfort in a lower rate of death. there are so many other things that are very dangerous and bad about this virus. don't get yourself into false complacency. >> now the president also said in that tweet that the u.s. has the lowest death rate in the world. he even capitalized

cnn's senior medical correspondent elizabeth cohen joins me now with the details. bout the vaccine candidate? >> reporter: you know, one thing that we know about it, kate, is that it's different. it works differently than the three that have gotten federal funding for large-scale trials from the federal government. that's good. you want to have as much variety as you can get because some of these might not work and you might want to increase your shots on goal, so to speak. right now novavax is studying this and i asked the ceo of the company when will you move on to the large 30,000-person large-scale clinical trials? >> i think in the fourth quarter. we don't have a date set yet but hopefully in early as the fourth quarter as possible. maybe if we're lucky we can start phase three in the late third quarter. >> reporter: now the ceo, he told me that he thinks they could have their vaccine on market by the first quarter of next year. kate? >> and the epa also just approved two disinfectant products that kill covid on surfaces. what does that mean? >> reporter: so th

elizabeth cohen joins me now. you spoke with the ceo of novavax.w soon could we see a vaccine from them? >> pamela, stanley says that we could see a vaccine from them as soon as possibly by the first quarter of next year. but of course before they do that, they have to study the vaccine. right now they're just doing preliminary trials of about 131 people. they still need to do the large-scale trials of 30,000 people. i asked mr. irk when do you think you'll be doing those. >> i think in the fourth quarter. we don't have a date set yet. but hopefully as early in the fourth quarter as possibly. maybe if we're lucky we can start phase three in late third quarter. >> now, novavax is joining three other companies that have gotten federal funding for their phase three large-scale trials. the first of though by moderna is expected to start their phase three trials later this month. >> and regeneron was also awarded $450 million by the government for its combination antibodies treatment still in late-stage clinical trials. how would that treatment work? >>

the head of "operation warp speed" said 90% to elizabeth cohen yesterday. it's a high number. >> it is indeed, dr. sanjay gupta. thanks so much. i appreciate your team and your expertise as always. >>> in just a few hours, millions of americans are set to lose key benefits that are helping to keep food on their tables and roofs over their head. that's unless congress acts. >>> then president trump just said that most american cities are doing real well with the pandemic. is that true? stay with us. over time, you go noseblind to the odors in your home.

week long lockdown will be imposed and by going to city after a spike there let's hear now from elizabeth cohen a. on the weekend we heard from the interior minister who said that the whole world is watching how one of the most successful battles against 19 has been fortunate india now it was that central government's decision again you know in late march to impose that nationwide lockdown one of the strictest in the world which didn't delay the peak of cases which we are seeing now which the states have taken over managing and as always it's important to remember with india that although it's increased testing so much at least $300000.00 tests being conducted every day it is still testing some of the lowest numbers per capita in the world mexico now has the 4th highest number of deaths from covert 19 in the world overtaking italy well the 35000 people have died it's recorded more than 300000 infections but the government says the true number is likely to be significantly higher. save the children says 10000000 may never go back to school because of the pandemic the charity says girls will be h

fauci, you may have heard the head of operation warp speed told my colleague elizabeth cohen that heised if the vaccine was about 90% effective. we've only seen early data, so that seemed like a significant estimate in terms of efficacy. what evidence is there to give people that amount of confidence to make a statement like that? >> i mean, that's obviously a very optimistic estimate. we all hope it's going to be that way. when we look at the data from the phase one study, relatively small number of people though it might be, it looks good, because the vaccine induced -- in the recipients are rather robust. the level that you would see is at least as good or better than what's induced by natural infection, namely what we're seeing in conslow less ent plasma. so that's the fird good indication that gets us to be optimistic. i'm not sure it will be 90%, but i think it's going to be reason w -- reasonably good. the animal data look very good. yesterday, data showed really good not only did it protect the animals, but the virus was not really seen in the nasal and the lung, which really

ari emmanuel and elizabeth cohen telling people not to wear masks because it wopt do any good because wear masks during flu season and it won't help. also if you don't have symptoms, don't wear a mask. and so you're going to hold the president to a different standard than you're holding your own programming. and i don't understand that. you want to talk about a shift, that is a shift. >> you are aware that administration officials, at the beginning, were advising people not to wear masks, because they wanted them reserved for front line workers. look, tim, there is a discussion to be had. >> that's not what your doctor said, brianna. it's a moving target with you. that's not what your doctor said. >> i don't have the quotes, tim. >> said that they don't help. >> tim, what i'm saying to you is there's a question from the trickle down, what came from the administration on mask and specifically coming from the president himself, as to the effect that that has had on people, and that is a conversation worth having. but here we are, months later, with the president finally wearing a mask.
