how far they've gone and what they've confirmed. joining us now, cnn senior medical correspondent elizabeth cohen. elizabeth, should we take this with a grain of salt here? you need to study vaccines over time on thousands of people before you can make reliable conclusions. >> right, jim. i wouldn't take it with a grain of salt. i would take it with a shaker, maybe even a gallon of salt. be extremely skeptical of this. the russians have put out no data. we're basically just taking putin's word for it that this is a fabulous vaccine. he said my daughter took it and she was fine. it doesn't matter if his daughter took it. that's one person. what you want to see is phase 3 trials of tens of thousands of people, and they haven't even done those yet. they're very straightforward they haven't even done those yet. how do we know this vaccine is safe or effective if they haven't tried it out in tens of thousands of people? scott gotly put it guest when he said i wouldn't take it. >> you make a very important point about scott gotly. what about vaccine experts? what are they saying about the president's claim? he said it a few times now that he believes a vaccine developed in the united states, elizabeth, can be ready by election day, november 3rd >> right. so the experts i've spoken with -- these are people at high levels. even tony fauci thinks a vaccine would be ready by december or january after election day. so what the experts i'm talking to are saying is, look, the only way we're going to have a vaccine by election day is if trump does what putin is doing, forget phase 3, put it on the market and everything will be fine. that's not how we do things in the united states of america. you have to have the phase 3s so i asked the director of the national institutes of health about this, and he essentially said to me not on my watch. he said if this happens, if political pressure is put to bear and the fda approves a vaccine before it's been shown to be safe and effective, his voice be among the loudest. he said tony fauci's voice will be new england loudest protesting it in saying this vaccine is not ready. so we have that from the national institutes of health director, that he would be the first one to say uh-uh, this isn't going to fly. >> but the president's done it before. he did it with hydroxychloroquine and still does it despite evidence that it doesn't work. whatever they say, we should be prepared for the president doing what he wants. >> right, exactly, because this worry that trump is going to pull this october surprise and put a vaccine on the market in october is not an idle worry. he could pressure the fda to do that. he pressured them to approve hydroxychloroquine and look how that worked out. >> elizabeth, thanks for the reporting. despite the global skepticism over russia's claim that it has the first really effective vaccine, vladimir putin is touting the development this morning. >> matthew chance joins us from moscow. to be clear, the russian government lies a lot. what do we know right now about the science here that we can take seriously, matthew? >> reporter: well, as elizabeth was saying earlier, it's hard to reach a conclusion about how effective and safe this vaccine is because the clinical data that you would normal put out at this stage for peer review just hasn't been made public. they're saying it will be, but it hasn't been yet and people will be more qualified than us. we'll be making that assessment. but what i can tell you is that, you know, regardless of whether this vaccine works or not, regardless whether it's safe or not, the russian government have approved it and it's going to be administered to frontline health workers in this country over the coming months and and to teachers as well. i can also tell you according to russian officials, a billion doses of this vaccine have already been ordered by countries around the world, 20 countries, they say, around the world. they're hoping to mass produce this vaccine to the tune of 500 million doses a year moving forward. and so, look, yes, i totally get that russia has lied in the past over a whole range of things. having said that, it does have a record going back through the soviet union in producing, you know, effective vaccines. and so it's got that kind of scientific infrastructure that it's been leaning on heavily. but undoubtedly this has been a political project from the outset from vladimir putin. the idea that russia could be first to cross the line, russia could beat the united states in getting to a vaccine, that's a very seductive thought for the kremlin, and i think that's probably what's been driving the kremlin to plow such vast resources into creating this vaccine before anyone else in the world can get there. again, whether or not it works, whether or not it's safe, it's still to be determined. >> a wise person wrote when you mix politics and science, you get politics. matthew chance, thanks very much. to florida now where hospitalizations of children with covid-19 are rising. as school districts welcome back students to the classroom this week. >> good morning, rosa. the concern is that there are areas with high positivity rates. >> reporter: you know, you're absolutely right. we know that at least 12 school districts are reopening this week for in-person instruction. but according to the florida education commissioner, all of the counties across the state that are in phase 2 of the reopening plan are planning to reopen for in-person instruction, and that is according to the emergency order that was issued by the state of florida. of course, except hillsborough county, the tampa area. they decided to reopen for virtual instruction and now the state is going to the strict there saying, look, you have to follow the law, you have to provide in-person instruction and give parents that choice. now, all this as we learn according to data from the florida department of health that in the past month, the number of covid-19 infections in children has increased by 137%. take a look at these numbers. on july 9th, the number of infected children jumped on august 9th to 39,735. you got to think about this. there was no school during this time period. if you look at hospitalizations, those are up during that same time period by 105% from 213 to 436. the deaths in children during that time period increased from 4 to 7, and yet governor ron desantis continues to push for the reopening of schools, last week also pushing for the return of girls and boys sports. here's his rationale. listen. >> the fact is, in terms of the risk to school kids, this is lower risk than seasonal influenza in terms of their ability to spread it, they are less likely to spread it than they are for that. >> reporter: now, top experts disagree with the governor. just yesterday the vice chair of the american academy of pediatrics on infectious disease told cnn's anderson cooper that experts do worry about influenza, that in a year it kills 100 children, and so far in just the past few months there have been 90 covid-related deaths in children. jim and poppy, i should add, i asked the governor directly what is your safety plan, your statewide safety plan for the reopening of schools, and he didn't have an answer. there is no statewide safety plan, and yet the push for reopening continues in the state of florida. jim and poppy? >> we need a plan. a statewide plan there, national plan. rosa, thank you. still to come, food insecurity. it is just one of the dire realities facing so many more americans today because of this pandemic. we'll see how one texas food bank is dealing with unprecedented demand. taking stock. it's nearly eight months after the first confirmed case of covid-19 in the u.s. but the nation still struggling to combat the spread. what can be done to control it now? is it too late in some respects? as schools shift to online learning, get access to computers and adequate technology, wi-fi, proving to be a challenge, especially in low-income communities. ahead, we'll hear how one school district is receiving some help to bridge the digital divide.

>> look, we should have a plan, a set of guidelines that parents across the country can follow. unfortunately we don't. you talk about some of those early guidelines from the cdc. they're pretty simple. wear a mask and social distancing. we don't seem to be doing that. yesterday the governor georgia talked schools reopening. he said this week went real well other than a couple of photos. now, of course we know what those photos produced, kids in masks in hallways being jammed together, many of them not wearing masks. consequently we've seen a resurgence of cases in georgia. it's not just georgia opening up schools for in-person classes. 9 out of 12 florida counties are expected today start face-to-face instruction this week despite the state having a coronavirus positivity rate hovering around 15%. >> yes, that's about six weeks from now. >> kentucky's governor now recommending that schools wait until late september to begin in-person classes. this follows multiple states opening schools only to see some shut down days later after reported cases of coronavirus as well as a new report from the american academy of pediatrics and children's hospital association stating that there's blood pressure a 90% increase in the number of covid-19 cases among u.s. children over the last four weeks. school districts across the country continue to evaluate whether they are adequately prepared to reopening classes. among those concerned, some school nurses like this one who will be on the front lines of covid when she returns to work in bucks county, pennsylvania. >> this will be and is unchartered waters for our schools, something we've never had to face. and the uncertainty is frightening. >> as of monday, the third largest school district in the state says they will start the year fully online. it's just the latest district to make that decision. of the 101 largest school districts in the country, over half are planning for online-only instruction in the fall. that's more than 7 million students starting the school year virtually. of the 25 largest districts, so far all but six have announced an online start. one of the few that will be open for face-to-face instruction at least part of the week, the nation's largest school district. >> first day of school is a magical day. >> reporter: new york city mayor bill de blasio says they're planning to send kids back. >> we can do it safely. we've set very stringent standards and we have to meet those standards. >> reporter: only a quarter so far opting for only-online learning, yet even remote learning is not without potential health risks and frustration as demonstrated by this video from mansfield, texas, showing parents waiting in long lines to pick up their children's devices. >> there's no way two people can serve the whole of mansfield. it's just ridiculous. >> another example of the school district not being prepared for the onslaught of parents coming to pick up devices. we should note in mississippi, another state that has reopened, the state health official said 22 different schools have reported cases so far. of the 34 cases, 19 were among students, 15 were with employees. we've seen a lot of school districts across the country also ask for rapid testing, the latest being florida. you know what all this requires? this requires money. and yet we still see that dead look in washington. of course these schools could use that money asap. >> money, a plan, and a commitment from this administration. thanks very much. >> sure. is time running out to get a handle on the pandemic in the u.s. before a crucial point and that's the beginning of the flu season. we're going to speak to an expert next. lose sight of your own well-being especially if you have a serious chronic medical condition. at aetna, we're always here to help you focus on your health. because it's always time for care. we know you're always at univethere for them.x, that's why our advisors are always here for you. learn more at phoenix.edu. they get that no two people are alike and customize your car insurance so you only pay for what you need. what do you think?

i'm joined now by a data analyst for coronavirus, other outbreaks. to mass puello. you've taken this 30,000-foot view to place us where we are so people understand. as you know, our viewers now by now, president trump did not have, really, a national strategy. gave a lot of freedom to states to decide what to do, how much to do, et cetera. without that national strategy, where does the data show the u.s. is on this outbreak, particularly before the fall flu season? >> very, very poorly. we didn't do what we needed to do at the national level, and the states were left to fend for themselves. they didn't do what they needed to do. you have a state like new york, who's doing everything they need. they still have 500 cases a day. and they have a ban for many states, but they have a million people coming in every day. that's around 1,000 cases a day coming into new york because quarantines are very soft. that's one of the more aggressive states. imagine the states not doing what they need to do. we have a small window of time now before the fall, but we can stop this at any time. it's not like, oh, my god, right now that's the -- the spread is low and we don't have to do anything. we can stop this at any time if we have the will. >> to do what? the will to do what? >> the states have focused mostly on just closing stuff, close schools or businesses. that's what we're discussing right now. but these countries that have controlled the virus without closing at the national level, schools or businesses, such as taiwan or south korea. but we're missing many other pieces that other states necessarily have to do to control the virus. one of them is, if you don't control the people coming in, your infections are going to come in. there are cases in the united states that states on their own need to control infections coming in, that's one. the second piece is the obvious test, trace, isolate. there are not that many states who actually test, trace, and isolate contacts. when they do, they ask as a favor, please, can you stay home, can you quarantine at home. how many of these people react to that and actually do it? very few. until we get the infected to stay home, that's not going to work. >> we're clearly not going to trace, test, and isolate, because the president doesn't want to. he says it every day, the only one reason we're having more cases is because we're testing more. that denies the facts of increasing positivity rates, et cetera. so without test, trace, isolate, what is the path of this outbreak looking like like at this country? >> countries can't move forward without test, trace, isolate. >> so more people are going to die? more people are going to die until you have a vaccine? is that the idea? >> well, until we have a vaccine or until another -- there's three ways. one, you have vaccine or treatment. the second is actually states realize that they're on their own and act as such and have proper borders and proper management of the situation inside of their borders. the third one is starting in january. >> you had a tweet where you asked if we as a country have learned from the pandemic of 1918 one years ago. it's amazing that 100 years later we haven't learned the lessons, it seems. >> it's pretty crazy. you look at what we knew then and the threat was the detail around in spain. they knew it was through droplets, spread through droplets through people speaking, talking. they knew you had to stay at home if you could and if you were going out, that you stay outdoors. they knew that you had to wear a mask and that people would say no, don't wear a mask. they knew some people would say, oh, no, no, this is nothing. they had also some treatments that they recommended that were absolutely fake, and the difference is that at the time it was tobacco and alcohol. now it's injecting disinfectant or bleach. the big difference is we thought we had learned, that there is a role in the economy for the government. but it sound like we forgot that lesson, at least in the united states, because here the best government is no government at the federal level. >> there's outright hostility here. people forget. >> that's right. >> i just wonder, then, there are a lot of models about how many folks are going to lose their lives as a result before you have a widely available vaccine. you're a data guy. which model do you believe? what do you find most credible? >> one of the good things is that we have better treatments now. it looks like between 20% and 50% of fatality rate might have been lowered thanks to them. and so let's assume the fatality is 5% of all the people who got infected. that is around 150 million americans, 0.5% of that is something like 750,000. so we're close to 200,000 deaths, in actual deaths, not the official ones. we might only have to go to around 700,000, so there's still a few to go. >> just a staggering number thank you for breaking it down. it's hard to digest the numbers, but it's good of you to help. >> thank you, jim. >> for sure, we need to hear those numbers, as tragic as they are. ahead for us, bridging the digital gap. it is a huge challenge facing so many children and their parents right now as so many skills shift to remote learning. what is actually being done to fix it. one fortune 500 country offering what they can to help. we have more on that ahead. wayfair has everything outdoor from grills to play sets and more one of a kind finds. it all ships free. and with new deals every day you can explore endless options at every price point. get your outdoor oasis delivered fast so you can get the good times going. ♪ wayfair. you've got just what i need. ♪ i'm a talking dog. the other issue. oh...i'm scratching like crazy. you've got some allergic itch with skin inflammation. apoquel can work on that itch in as little as 4 hours, whether it's a new or chronic problem. and apoquel's treated over 8 million dogs. nice. and...the talking dog thing?

>> yes. it's strange and getting used to a new way of learning, a new way of connecting. yesterday there was a lot of creativity in terms of virtually building relationships with students, staff, and in partnership with salesforce and so many others we've been working to figure out how to ensure every single student has a device, connectivity and tech support. it has been just a huge undertaking, and we are looking pretty much day-to-day to connect with families and students to make sure they have what they need. >> you're both products of the public school systems in your respective cities. for you, superintendent of oakland, you went to the public schools. stephanie, you went to public schools in san francisco. 7 million children across america lack high-speed home internet access. more than 7 million don't have a device to learn on. i'm interested if you could share what salesforce is doing in your announcement this morning and where it came from. >> i think the why, poppy, is that covid-19, as we're seeing, has completely transformed and will continue to transform every aspect of our lives. one of the most notable is in education. so a few months ago we launched work.com for businesses and governments to allow them to reopen safely. as districts like usd are planning to return to the classroom, we're announcing work.com for schools. really, what that is is it's a technology command center that gives schools tools to reopen safely, whenever that may be. we're also really excited to announce $20 million in grants to five public school districts across the u.s., oakland, san francisco, indianapolis, chicago, and new york. this really brings our total global investment in public schools to $118 million with $85 million going straight to san francisco and oakland school districts. >> i'm glad to see that they can get that help for sure. but superintendent, to you, i mean, the fact that the private sector has to step in here in this way, does it show failure of government to be able to provide equal access for all our kids in this crisis? >> i would say what this crisis has shown overwhelmingly are the deep inequities that have existed in our nation for a long time, particularly the crisis that all major districts, particularly urban school districts that serve a high percentage of low-income and students of color is that really the device piece, it's really a human right similar to electricity and water. it's pretty impossible to engage in society without those tools. and so what we're doing is with partnerships like salesforce and other business and community-based organizations, we're hitting the ground running to do what we can while we do the necessary work in terms of state and national policy so that we can be in a situation where we don't have to keep having to have these major fundraising, creative events in order to get what we need. >> i truly believe you need sort of private/public partnerships always. the government can't always do it all, but i do think we've seen a failure of government on so many levels. if you see what mark benioff did a few months ago, working to coordinate flying in ppe for hospital workers from overseas because they weren't getting enough of what they needed. can you just speak to as a company what it was like to recognize, look, like, the government's not going to fill the gap here, there are going to be a ton of kids in our home state facing this inequity. how is that decision made? >> poppy, we believe at salesforce that business is the greatest platform for change. we're really focused on that. so we want to use the tools and resources that we have to get involved because the government alone, as you mentioned, can't do it, right? so it's going to take public/private partnerships to make this work. so at salesforce, we've been giving to the schools for eight years, and we're doing it again because this year our schools need us now more than ever. it will be one of the most difficult school years in history for administrators and students alike. it's been a privilege to work with district leaders like kyla or innovative and recognizing the need for partnership and it need to do more to keep the students safe. >> can you talk, superintendent, finally, about the latest data from april that showed us that 9 million school-aged children in america right now are not going to be able to fully engage with their school online, not to mention the workers that have to leave the home and can't afford child care to help their children with these assignments. what are you up against even if you have adequate resources, wi-fi connectivity for all your students? >> a lot of what we're up against is a huge need for support, particularly around social emotional learning support and the food insecurity we're seeing. and so our mission in oakland and our vision as a district is that we believe that we're best positioned to close opportunity gaps through partnerships, and that is why we have reached out and we really rely on our long-standing partnerships with business partners like salesforce. we have a lot of other partnerships within our city as well. and so we are seeing on a daily basis just some of the challenges around social isolation for students, food insecurity, just all of the impact of unemployment and the unpredictability and just the unknown of the situation right now. and so we feel that it's our responsibility as educators to leverage the support so that families are in a better position to support their students with the learning. and so i do see this as an ongoing situation. salesforce has been a wonderful partner with us in conjunction with eat learn and play foundation to enable us to provide fresh food to families. food security is an area we're particularly -- >> i'm so glad you brought that up because school is where many students receive nutritious meals, both breakfast and lunch. good luck as you get get the school year off to a start. we appreciate you so much. remarkable video, hundreds of cars lining up at a dallas food bank. organizers say they're facing unprecedented demand amid the economic slowdown from the pandemic. a live report after the break. ♪ come on in, we're open. ♪ all we do is hand you the bag. simple. done. we adapt and we change. you know, you just figure it out. we've just been finding a way to keep on pushing. ♪ that paved the way. find their stories. make them count. at ancestry. make them count. start your day with secret. secret stops sweat 3x more than ordinary antiperspirants. with secret, you're unstoppable. no sweat! try it and love it or get your money back. -always have been. -and always will be. never letting anything get in my way. not the doubts, distractions, or voice in my head. and certainly not arthritis. new voltaren provides powerful arthritis pain relief to help me keep moving. and it can help you too. feel the joy of movement with voltaren. right now this proves the struggle for millions of americans in this pandemic and just how real it is. >> take a look at this. these are aerial shots. look at the line of cars. that is in dallas this morning. they're lined up for a food bank with people desperate, in need of help to feed their families. ed lavandera has more. >> reporter: in the middle of the night, a fleet of trucks carrying more than 10,000 boxes of food arrive in a desolate dallas parking lot. >> probably drop them here. >> reporter: valerie hawthorne is making sure all the crates are perfectly lined up. the last time the north texas food bank sponsor add drive-through food giveaway was in may, and hawthorne knows life has only become more desperate for millions of people struggling through the pandemic. >> these distributions truly reveal what the need is and how many of our community members are just one paycheck away from hunger. so we have to be out there to support them during this time. >> reporter: first people in line were pauletta johnson who arrived before the food drive even started. she's on a fixed income and cares for her grandchildren. arthur's work has dried up. >> i'm here to feed the grandkids. it just means a lot. i don't really have the money. i'm on a fixed income and i don't have the money to buy some of the things that i need to get. so that's why i'm here this morning. >> it means a lot, you know?
