sanjay gupta is with us now. it came out this morning. people can read the essay on cnn.com. i haven't had a chance to read all of it yet. i assume you came at this both as a doctor but also as a parent. >> yeah, absolutely. i think that having covered this now for a year and a half, we've always framed this as a race. the vaccines, they would come one day. it would be the race between the vaccines and the virus, now the vaccines and the variants. they had a finish line number, if we drop below 10,000 cases per day, we could say as a country we could go into containment mode, finally get our arms and hands around this virus. we didn't get there. we got tantalizingly close, 11,299 cases per day. that's our lowest that we got. now the numbers are starting to creep up. i kept wondering, is this going to be these blips on the radar or are we going to see disturbing trends. as miguel and elizabeth talked about, these are becoming disturbing trends. this is the best time of the year in terms of viral transmission. it's summer. the virus doesn't like to be outside. as we go into the

sanjay gupta. and, sanjay, just to be clear, dr. walensky is saying this is new.s is something they are seeing that is new with the delta variant, that people who have been vaccinated and are infected, they may not be getting sick or seriously ill, but they are transmitting the virus, which is part of the reason the cdc is now recommending people mask up again in these highly impacted areas. she also did say, though, that almost most of the transmission is happening from unvaccinated to unvaccinated. still, you know, what's your reaction to what you heard? >> yeah, well, i thought that was really good interview, john. i think the fundamental problem -- we just have to state the fundamental problem, exactly what you said. everything else left aside for a second, the fundamental problem is still in this country, unvaccinated people are transmitting the virus to unvaccinated people, and that's who is getting sick. that is who the doctor you interviewed from louisiana was talking about. that is still the fundamental problem. what dr. walensky is referring to seems to

sanjay gupta joins us now. great to see you as always.it for you in your position where you've tried to guide us every single day through this pandemic to now see cases spiking? >> i thought we'd be having a very different conversation right now. i mean we started to have this different conversation as we saw the trend lines all improving. you and i talked about when the cdc lifted the mask recommendations that was a sign maybe things were near the finish line and, frankly, they were near the finish line. the reason i decided to write this article is because we've talked about this race for some time between the virus and the vaccines, between the vaeriants and the vaccines and we had a finish line determined, which was fewer than 10,000 cases per day. we got tantalizingly close to that, 11,299 cases and then the number started going back up. this is concerning. we still have the capability to really contain this. but right now the numbers are going back up at the same time that the vaccinations are falling. so we're not vaccinating enoug

sanjay gupta. doctor, good to see you. thanks for joining. >> hey, don.talk about variants and rising-case numbers, people need to know if you are vaccinated. you're protected from serious illness or death, am i correct? >> yeah. no. that -- that -- that is -- that is what the initial trial showed. and now, you got, you know, close to a billion people who have received vaccines around the world and the real-world data reflects that. as you just mentioned, don, 99% of people who are ending up in the hospital are unvaccinated. i mean, that -- that is a -- that is a -- quite a crucial statistic, if you think about it. it's still out there. it's still making people sick. but 99 times out of 100, someone's getting sick enough to go to the hospital, it's because they haven't received the vaccine. >> what about breakthrough cases, sanjay, that we are hearing about? a cluster here, on the east coast. the town manager of provincetown, known as p town, a popular-beach destination in cape cod, says that he is aware of positive-covid cases and a number of them are br

sanjay gupta. sanjay, this is a worrisome concern, right?seeing the delta variant taking root exactly in the regions that do have a lower vaccination rate, now nationally cases up 10% over the past week. i believe cdc director rochelle walensky said we should expect more illness and death. how concerned are you? >> well, this is a much more transmissible variant and there is some evidence now coming from the uk that it can make people sicker as well. sometimes things become more contagious and they make people less sick. they trade-off contagiousness for illness. we'll have to see with this delta variant how this plays out. if you look at the country as a whole, as you mentioned, cases up a bit now about 10% over the last couple of weeks. but if you go back to january, down 95% since then. so is this more of a blip on the radar or is this the beginning of something that's more concerning? and then as you rightly asked, do we see the corresponding increase in hospitalizations and deaths? we don't know yet. the vaccines are really protective,

sanjay gupta. sanjay, let's start with the question on the minds i'm sure of many of our viewers. i'm vaccinated, why do i need to wear a mask? >> uh-huh, right. so, first of all for you, jake, if you look at that map, if we can put that map back up again. what we're talking about here is areas where the virus is spreading in high or substantial ways where you are, as it turns out, d.c., is moderate. this is maybe going to confuse people even more. but, technically speaking according to this new guidance, in d.c., that wouldn't apply for vaccinated people in public indoor spaces. >> but you're in the red, right? you're in atlanta so why do you need to wear -- >> this is what they're saying. the new thing here, we've known for some time that vaccination rates aren't where they should be. we've known for some time that the delta variant has become dominant. so what changed now, is your question. the new data that the cdc is talking about basically states that someone who is a vaccinated person who develops an infection, a so-called breakthrough infection, could be carrying the same

sanjay gupta. sanjay, what do you think of this new data that the cdc director just explained is driving the change in the guidance? >> well, i think this is concerning data. when you're vaccinated, you're still very well protected from getting sick. but it was sort of a question mark, how much does it protect you against actually potential becoming infected and transmitting the virus to others. we've known that people can get infected for some time. that was even true from the original clinical trials. with this delta variant, it's become increasingly clear, at least with dr. walensky, based on data we haven't seen. she has told me personally she's seen this data, that someone who is vaccinated and infected, the so-called breakthrough infection, they could carry the same amount of virus as someone who is unvaccinated and infected. the vaccinated person is still very well protected from getting sick in all that. but the idea they could potentially transmit is what she says is driving these new recom

sanjay gupta. njay, what concerns you the most about what the government of tennessee is doing in terms of no longer encouraging outreach when it comes to the covid vaccination for teens or vaccinations in general to minors? >> it's a clear sort of politicalization of a very sacred part of public health. we've seen this before. i've been reporting on these types of things before even before covid, you remember there were measles outbreaks in various places around the country. this is a clear politicalization of it. i think that's the bad news. the good news i think what the doctor was sort of alluding to is that tennessee in 2020-2021 were doing pretty well with regard to pediatric and adolescent vaccinations. but now, you know, will this lack of postcards going out to remind people of second doses, outreach programs to remind people to get some of these pediatric vaccinations, will it make a difference? will people still go ahead and get vaccinated despite this politicalization? i hope so. i think

sanjay gupta is here ahead of the announcement. sanjay, let's start with your reaction of what we are expected to hear from the cdc. >> well, you know, i mean this is obviously not the news people want to hear right now because it is going to appear like we're going backwards. i think if we rewind back to may 13th when i think it was on your program talking about -- >> you were. >> -- the fact that the mask guidance -- yep -- was changing at that time, it was a cause for celebration certainly but i will tell you there were public health officials even at that time who said is this the wisest decision at this time given the potential transmissibility of the delta variant. what is driving this decision today, and i think this is really important, is new data that has not yet even been published, that has been reviewed by this team that's been looking at this guidance that basically says this. if you are a vaccinated infected, breakthrough infection individual, you probably could carry around the same viral load as an unvaccinated infe

sanjay gupta joining me live from toke . it's been a long day, 24 hours. ou since this morning on cnn. this morning here in the states. listen, sanjay, we're already seeing more than 60 covid cases tied to the olympics and games. the games haven't even started yet. with vaccinated and unvaccinated people gathering from hundreds of countries, don't you think this was bound to happen? >> yes. i do, don. i think this has been the sort of challenge all along. you talk to the conference organizers and they say we would expect positive cases. about half those cases by the way, don, are from japanese locals. about half from international athletes but as you point out, we haven't really even begun yet so those numbers are likely to go up. one thing i want to point out. if you ask people what is the breakthrough infection rate in vaccinated people? what is it? we keep hearing it rare. it's hard to know because in the united states, testing has come way down since the end of last year. if you're vaccinated, you probably haven't gotten tested again, right unless you h

sanjay gupta is in tokyo live with us this morning. we just got an update in numbers, sanjay. so now it is 61 cases linked to the olympics and 33 are from residents of japan and 28 from the olympics, includes athletes here. based on the numbers so far and the size of the overall group coming into tokyo, is that a concerning percentage at this point? >> reporter: well, you think it is still seems like it is relatively rare, these type of infections. we don't know what percentage of those people that you just listed there have been vaccinated or not. vaccines are not mandatory here, jim, as well. one thing i will say, just as point of reference, in the united states if you've been vaccinated, you're not getting tested unless you go to something like this. i had to get tested at 96 and 24 hours and again when i landed here. the point is we may see more infections, a higher breakthrough infection rate than we have previously known but i don't know that that means people will be getting sick or seriously ill, which is the big question. >> okay. so how concerned should we be about t

sanjay gupta has this report. >> with the first pre-season game less than two week as way, the national football league is sending a warning to unvaccinated players. cnn obtaining this memo sent leaguewide on thursday saying, if a game cannot be rescheduled within the current 18-week schedule and is canceled due to a covid outbreak among nonvaccinated players, the club with the outbreak will forfeit the contest. the threat comes with financial consequences, too. according to the memo, if a -- >> last year when we did not have a vaccine to help out, the nfl held a game on every day of the week. if the nfl does not want to do that again, nor should they do that again if there is science that can be relied on to make things potentially easier and safer. >> some current players like deandre hopkins turning to twitter to complain about the new rules. the arizona cardinals wide receiver tweeting and deleting, never thought i would say this, but being put in a position to hurt my team because i don't want to partake in the vaccine is making me question my future in the nfl. and buffalo bills'

sanjay gupta. good morning. >> good morning. >> very basic question for folks, and hopefully we can show them the map, where this may apply to them or may not. i'm vaccinated. i live in new york city. it's yellowish, orangish on that map. do i need to wear a mask? >> i think new york city is considered substantial spread with regard to viral transmission. that means 50 to 100 per 100,000 people new cases. i think it would apply. this is a little bit of a moving target. it's almost like checking the weather ref reday to figure out if you need to take an umbrella. the mask is going to be sort of like your umbrella. two-thirds of the country following into this category of high or substantial spread. those are the areas where the cdc say, even if you're vaccinated, you need to wear masks in indoor public spaces. the thing is, poppy, going into the drier weather, viruses tend to spread more. you've got to keep an eye on your local area to find out what's happening there. >> dr. rochelle walensky, the c

sanjay gupta. sanjay, this development really underscores the risk to these athletes that we're seeing in the village. >> reporter: yeah. no question about it. obviously, a lot of focus on the games and what's going to be happening when these games start, but this is a big public health challenge as well. i'll tell you this. we talk a lot about this term breakthrough infections, people who still test positive despite having been vaccinated. you get the sense that we don't really know how common that is, but these games, because of all the testing that goes on, may give us a better sense of that. there may be a lot more people who do test positive. they may be vaccinated and still get this positive test. we talked through the whole process, trying to get an idea of how they're planning to do this and what they're doing to keep everyone safe. last year, these stadiums sat empty. as tokyo 2020 was officially postponed. many people assumed the games simply wouldn't happen. now they are happening. so i'

let's go to cnn's chief medical correspondent sanjay gupta live in tokyo. you just heard the tokyo 2020 olympics chief saying he's not ruling out an 11th hour cancelation of the games. what's your reaction? >> it's really surprising in some ways because we're here. there's obviously been a lot of preparations. but at the same time from a public health standpoint not that surprising. you are dealing with obviously the olympic games, 200 countries, more than that being represented, states and territories, many of these places, they don't have adequate vaccine programs. in japan itself, only 12% of the country has been vaccinated. the numbers have been going up over here, 80% of japanese locals did not want these olympics to happen here at this time. it's one of these things i think historically we'll look back on it and say was it the right move? so we'll see. but from a public health standpoint i don't think people are that surprised. >> there are now 71 cases that we know of now associated with these olympic games. we don't know much about the 71 cases. the

sanjay gupta and dr. paul offit. he's a member of the vaccine education center of children's hospital of philadelphia. sanjay, the u.s. is now averaging more than 61,000 new covid-19 cases every day. a month ago we were seeing just 11,000 new covid-19 cases a day. can you put this into perspective for us. how bad is this getting? >> well, i mean, i'll preface by saying this is supposed to be one of the better times of year, the summer, when the virus doesn't transmit as much. you just said the numbers in terms of cases. they've gone up nearly fooivefo, but if you look at the map, two-thirds of the country are in areas where you have high or substantial viral transmission in addition to the cases going up, hospitalizations have increased 35% over the past week, sadly deaths have increased 22% over the last week. all of those numbers going in the wrong direction. vaccinations overall, thankfully, at least over the past few days have increased a bit, so there are more people who are getting vaccinated now than this time

sanjay gupta is in tokyo where covid has shaken up the olympic games. also dr. lena wen. sanjay, as you wrote just last week, we got very close, tantalizingly close in the race against covid. now, as i mentioned, we find ourselves in this unsettling, confusing time. from a medical perspective, where are we in the course of the pandemic now? >> well, you know, if the country came in for a checkup right now, anderson, i think the doctors and nurses would tell them they're concerned. i mean, you have about a third of the country now that has high levels of viral transmission. we're in july. this is supposed to be the best time of the year as far as viral transmission being low. people are outside, the virus doesn't like to be outside. this could be as good as it gets, at least for a period of time. and yet a third of the country can take a look at the map. viral transmission is high. at the same time that the viral transmission is high, vaccination rates are low. i mean, they're really remarkably low. i have to tell you, i'm here in tokyo. we have been talking a lot about ath

sanjay gupta is in tokyo for us right now. how much of a problem is covid posing for the summer games, which as we all know began on friday. it's coming soon. >> yeah. good morning from tokyo, jim. first of all, i'll tell you, the mood is very different, jim. you and i have both traveled to these types of events. the planes are empty. coming over here, we had to all be tested. there is lots of procedure things. we're seeing that manifest in the olympic village as well. there has been about 60, 61 now infections, people who have tested positive, i should say. about half from japanese locals, about half from overseas visitors. and basically it's causing an issue where people then have to be isolated, as you know, and then contacts have to be traced and people have to be qua quarantined. for these people that have had contact with people who have become positive, their lives change as well. they have to go into quarantine, as i mentioned. we're going to see this over and over again. we're not seeing people get really sick as you

sanjay gupta, cnn chief medical correspondent.e delta variant, your reaction to what we heard from dr. walensky today about it being -- spreading among fully vaccinated people? >> well, you know, there's been some evidence that's sort of been accumulating around this for some time. the evidence that she was citing has not yet been published so we want to see that data when it comes out. but the idea that the vaccine does we've known that from the trials going back to the end of last year. but even then, they said 90%-plus effective at keeping you from getting sick. but could you still carry the virus, not know it, not have any symptoms? that's what she's alluding to. and when they dug into that d data, they found that people who are vaccinated and carrying it can same the amount of virus as people who are unvaccinated. so people can spread it to unvaccinated people. and that's what is, i think, driving this new change or update in mask guidance. i do want to be clear. the primary problem is unvaccinated people spreading the virus

sanjay gupta. we put those vaccination numbers up there. 99% of the people dying right now are unvaccinated. we reached the optional portion of this pandemic, which is in some ways is truly scary. you have an essay about what it means to be unvaccinated in america right now. >> yeah. i thought a lot about this obviously and been reporting on this for some time, celebrated i think with all of you when the vaccines were finally made available to people. and really relished the impact they would have. what the essay was and what prompted this is it's been this race that we talked about for some time, right? the vaccines versus the virus, the vaccines versus the variant and there was a finish line that was sort of put out there. how would you know that you could sort of look at this thing in the rear-view mirror. that was arbitrary but the number was around 10,000 cases per day. if we got to 10,000 cases per day in this country, we could say we have gone from trying to slow this thing down to containin

sanjay gupta. sanjay, i mean, have you heard stuff like that before? people going in for the vaccine but only they can do it without anyone else knowing? >> no, i -- i have not heard that. and, you know, i have been at this a long time, anderson. we did a full documentary about vaccine hesitancy. and there's clearly, it's existed for, you know, even before this pandemic. but the -- the idea that, you know, you know the right thing to do. you recognize the triumph of science. you realize it can save your life. get your life back to normal. and you, still, feel ostracized, perhaps, by going and doing this. it's -- it's -- it's really befuddling. the one thing dr. frase said there, near the end, is that ultimately it's still a win because these people are getting -- those people are still getting vaccinated but that's extraordinary. and i think, really tells the story of what's happening here. >> more and more, we are seeing, you know, large companies like google step in to fill the void left by the government when it comes to mandating vaccinations for t

sanjay gupta. sanjay, what are you seeing?> reporter: well, guys, you say that there's fewer than 1,000 people that will be inside olympic stadium behind me, it holds 68,000 people. that gives you an idea of what it will feel like in there. we'll see what it looks like on television, but the feel will be different. i want to go back to something you were talking about with the nfl. it's interesting because sports so many times throughout this pandemic has led the way in terms of making some changes. you know, with the nba bubble, for example, this nfl policy will be really interesting. it will be provocative and contentious but might make dampbs. we took a little deeper dive into it. take a look. with the first pre-season less than two weeks away, the national football league is sending a warning to unvaccinated players. cnn obtaining this memo saying if a game cannot be rescheduled within the current 18-week schedule and is cancelled due to a covid outbreak among nonvaccinated players, the club with the outbreak will forfeit

[ applause ] and there's much more to come. so good luck to courtney, mark, and rebecca. i hope you earn a lot of money for both yourselves and the charity i selected which is odyssey atlanta. let's play "jeopardy!" with these categories. starting off with... courtney, please take us away. disney movies for $200. mark. what is, uh, "toy story"? you got it. keep going. bordering the usa, $200. - mark. - what is vancouver? correct.

sanjay gupta live in tokyo. sanjay, i understand there is a delay, but folks here are very concerned in the united states given that nationwide, 83% of all covid infections are the delta variant. so help folks understand just what's happening specifically with regard to these breakthrough infections in the delta variant. >> well, you know, this was sort of anticipated. when you have a variant that is far more transmissible than the previous strains, it's going to essentially outrun those other strains and become a larger percentage of the overall cases. if you go back to may, i think we can show you what was happening. in the beginning of may delta was a very small percentage of what was happening in the united states. we weren't talking about it much at that point. over time it was doubling or tripling every couple of weeks and now we get to this point where it's the majority of infections. and that was sort of expected. there's two things about this. one is that it is far more transmissible, far less forgiving

sanjay gupta joins us on the phone. what more does this new data say? >> well, this gives us a really granular look at a particular outbreak. so it's interesting data. we've been looking at a lot of these data sets and broad populations, but this looked at barn stable county, massachusetts. and i think we can show the numbers here. basically they found that 469 people, residents were infected in the month of july. and 74% of them had been vaccinated. 79% of those vabs nated people did report some symptoms, and the delta variant, no surprise, because it is the dominant variant in the whole country, was the main culprit of infection. but it's really, you know, this idea that people who have been vaccinated could still carry the virus and that virus could be transmitted. what they showed was that people who were vaccinated and then tested positive had similar viral loads to people who were unvaccinated and became infected. that was something -- that was data that had been percolating for some time out there, but that was sort of the big thing. i will tell

sanjay gupta. they're both in tokyo. g with a lot just reporting from over there. so thank you so much for what you are doing. sanjay, you attended the opening ceremony as a doctor, a journalist, but also one of very few people able to take in the olympic games in person. tell us about what experience. what was it like? >> well, you know, i mean, as you have heard so many times over this past week, it was strange. it was weird in many ways. it was magnificent for the event itself, and that olympic stadium, that national stadium which they built is a really majestic place, jim, i got to tell you. but it is this tale of two cities. you have the excitement of the olympics and the anxiety of the pandemic. people in japan said stay home, watch this thing on your television. when i was outside, there are tons of protests and it was very loud, people on the stroeets. i want to show you this video i took on my phone as i was walking in. going from the streets with lots of protests, lots of noise, come around the corner and there

sanjay gupta has more from japan. >> reporter: last year these stadiums sat empty as tokyo 2020 was officiallyd the games simply wouldn't happen. but now they are happening. so i've made my way here to tokyo to try and figure out exactly how they're going to pull this off. >> he had no idea what was coming in terms of covid. >> reporter: postponing the olympics again was no longer than option due to international sports schedules. so it was up to the chair advising the committee on countermeasures to figure out how to hold the games in 2021. was it just going to be inevitable the games would happen, ju had to figure out how to do it as safely as possible. >> they could be cancelled completely. that was always part of the thinking. we can only do this if we are satisfied that we can do it safely and securely. >> reporter: while we have seen other sports make it through seasons or tournaments safely with little interruption, the olympics bring a unique challenge. more than 11,000 athletes representing 206 different countries, states and territories will descend on an island nation currently figh

sanjay gupta who is live at the event for us. good morning, just set the scene. it is as laura mentioned the covid olympics and it is being held in a city under a state of emergency. >> reporter: yes, i mean the scene is that in many ways it is a tale of two cities. you know, you have excitement and you have anxiety. you have the excitement of the olympics for sure, but you have the anxiety of the fact that this is the first -- really the first global gathering of this size since the pandemic began. so athletes will be tested obviously during the olympics, but the public health officials are being tested as well. and it is challenging. as you point out, it is a state of emergency here, but let me show you the numbers. i don't know if you have a graph that we can put up. you have these peaks and valleys here in japan with regard to the covid numbers, that recent low followed by the peak of may 14th, that was just about a month ago. over the last month the numbers are going up and that has caused conste consternation. if you talk to people on the street, roughly 8

sanjay gupta is there on the ground in tokyo for you. thank you for staying up for us. what are you learning about this gymnast and what it could mean for the team? >> reporter: yeah, so this is another person who was tested here on the ground and that test came back positive. we're not certain whether or not she had been vaccinated. vaccines are not mandatory here, kate, for people within the village. though people do get vaccinated, it is not mandatory. we don't know that. and a person is asymptomatic and mild symptoms but have close contact with another athlete so the person that tested positive now in isolation and the person with the close contact now in quarentine and so it goes, kate, this is part of the issue here. they're doing very regular testing. i got tested to be here 96 hours before, 72 hours before and then when we landed. but these breakthrough infections, these infections that are occurring in vaccinated people, oftentimes with little or no symptoms, we're going to see how frequent they are, really within this olympic village. we haven't had a case stu

sanjay gupta! [cheers and applause] thank you, johnny gilbert.s of being able to guest host "jeopardy!" is that the show is matching the cumulative winnings of all the contestants during my two weeks here and donating that amount to a charity of my choice. i've selected odyssey atlanta, a wonderful program that offers educational enrichment to students in atlanta who might otherwise have not had access to it. so courtney, s.a., abby, thank you very much for that. hope you have a great game. good luck, and let's begin with these categories. starting off with... there are two words in each correct response there. and... courtney, you're our returning champion. - you start off. - world of empires for $200. s.a. what is the holy roman empire? you got it. i'd like to thank the academy for $1,000.

sanjay gupta looks at the challenges it faces. >> reporter: it was never going to be easy. medal of a pandemic in a city now in a state of emergency. the usual fanfare, muted. making way for concerns over covid-19. while it is true that no kuchb in country in the world was prepared for this pandemic, japan faired better than most. they are an island nation, it wasn't that hard to get people to isolate here, people wore masks without much dipgtfficult. and they also have hundreds of these, think of them like hundreds of cdcs all over the country. i spoke with the director of one of these. >> translator: we have been preparing for seven years to prevent risks for the tokyo olympics. >> reporter: according to a poll about 80% of residents here in japan did not want the olympics to happen here at this time. what about you? what do you think? >> translator: in 1964, the last tokyo olympics, because japan lost the war, the games worked as an opportunity for us to come back. in this olympics, we have fukushima. >> reporter: he is talking about the nuclear disaster triggered by an

sanjay gupta joining us now from tokyo on the eve of the olympic opening ceremony where covid has veryk about the games here in a moment. first, though, sanjay, look, this is not what people want to hear, right? if they're vaccinated, they're hoping that they were able to get back to normal, and i wonder if that's going to inform what we're going to hear possibly from the administration. what do you think they might be considering here? >> well, yeah, you're absolutely right, first of all. i think it would be a blow to the psyche of our progress with covid, and the cdc's official word is that they're not planning on changing their recommendations at this point, their guidance at this point. but, look, we see the numbers. we see what's informing some of these decisions. i want to show you a couple of these graphs we put together to give you an idea of the trend lines here. may 13th when the mask guidance changed, where they basically said if you're vaccinated, you no longer need to wear a mask any more. you see the numbers went down overall for a period of time, but then they start toda

sanjay gupta. have you heard stuff like that. people going for the vaccine but only if they can do it without anyone else knowing? >> no, i have not heard that. i've been at this a long time, anderson. we did a full documentary about vaccine hesitancy. it's existed even before this pandemic. the idea you know the right thing to do, you recognize the triumph of science, save your life, get your life back to normal and you still feel ostracized by going to do this. it's really befuddling. the one thing dr. frase said is it's still a win. they're still getting extraordinary. really tells the story of what's happening over here. do you think it's a good idea to mandate vaccines for employees? >> i think we're at that point now, anderson. i mean, you know, the thing is i, again, have been reporting on this stuff for a long time. there are mandates that already exist. all 50 states have mandates for childhood vaccines, some have exemptions, different kinds of exemptions. universities have a new concept overall. it's interesting going b

walensky there, sanjay gupta said the same on our air yesterday, that if you are vaccinated, that you people do, whether they get vaccinated themselves. but for us who are vaccinated, should we have a reasonable sense of comfort as to our own personal risk from the delta variant? >> those people who are vaccinated should feel very safe we are protected from severe illness due to the delta variant. it is extremely unlikely we're going to end up in the hospital or die. we are seeing more than 99% of people dying from coronavirus now are people who are not vaccinated. so that illustrates how well the vaccine protects against the delta variant. however, we don't know. and i think the cdc really needs to step up and do a better job of tracking breakthrough infections with the delta variant. it's believed that with the delta variant, you carry more virus in your nose. you're able to infect more people if you're unvaccinated. vaccination reduces the level of virus you carry. how much less are you able to infect others? we don't know. >> a lot of debate over mandating in schools, what's going
