United states and all around the world. This is new day. Its tuesday, may 26th, 6 00 here in new york. And this morning, an important marker. The city that saw the first real coronavirus outbreak on the east coast, the original hot spot here, begins phased reopening this morning, after nearly three months. Nationwide this morning, though, there are some new worries. 17 states are seeing an increase in new cases, with five of them up more than 50 . 13 states are Holding Steady and 20 are experiencing a decline. It will be weeks until whether we know whether our relaxed restrictions for the memorial day weekend causes cases to spike. Some Health Officials in parts of missouri are now calling on everyone who attended this packed pool party in the ozarks to selfquarantine. John, theres also new information this morning about the impact of coronavirus on children. A majority of states are now investigating hundreds of cases of that pediatric inflammatory syndrome. These cases are very rare. At the moment, we only know of 350, which, of course, is a fraction of the total amount of cases. But these cases with children could have a big impact on the thinking of reopening camps and schools. So we have a lot to get to this morning. Lets begin with cnns brynn gingras. She is live in new rochelle, new york, where it is a new day. Brynn . Reporter it certainly is, alisyn. Really across the country, though, it was hit or miss over this Holiday Weekend when it came to those safety precautions, Wearing Masks, keeping social distancing. This as the country is nearing that devastating milestone of 100,000 deaths due to the coronavirus. But here in new rochelle, youre right, it is a new day. Officials are saying, be smart, be safe, remember this area is one of the first to shut down in the entire country because of that hot spot. And people here want to look forward, not back. Reporter new rochelle, new york, was the states first coronavirus epicenter. And this morning, its part of two regions scheduled to begin reopening this week. Governor andrew cuomo reminding new yorkers, its important to stay smart. The number goes down until you go out and dont do the ppe and dont do the mask, and then the number will go up. And whos going to determine what happens to the number . The person in the mirror. Reporter at least 17 states are seeing an uptick in coronavirus cases over the past week, including arkansas, where some enjoyed the weather without taking safety precautions. I see im not the only person. You see no mask here. You see no fear. Reporter the governor urging people to be more responsible. When you wear a mask, youre expressing your concern of someone else. So were trying to set the right example and continue to do that. Reporter cases are also increasing in alabama, where crowded beaches last weekend concerned local leaders like the mayor of montgomery, who earlier warned his city is critically low on icu beds. It gives me pause to think about what we may see in the next week or two, when people get back to their communities from vacationing down the gulf coast. Its problematic for me that people are cavalier about their behavior. Reporter chilly weather keeping crowds light at some northeastern beaches. At delawares rehoboth beach, face coverings are mandatory on the boardwalk and encouraged on its shores. I was very impressed with what i saw and i feel very much much more comfortable about rolling into the first of june. Reporter but at this new jersey beach, most people who walked the boardwalk did so without covering their faces. Officials in st. Louis asking people who attended events like this pool party in the ozarks to selfquarantine for 14 days. The risk of contracting covid19 is exponentially increased. Reporter take a look at this crowd in texas. All river tubing in close proximity. If i get it, everybody else getting it, eh . Its life. Reporter and this social media video from houston showing a pool party at a club with very few masks in sight. Houstons mayor says police will begin enforcing capacity limits after hundreds of social distancing complaints over the Holiday Weekend. We have to pump the brakes. People are there are some who are pretending as though this virus no longer exists. And quite frankly, its not only endangering themselves and those who are at these gatherings, but theyre endangering everybody else, when they leave these gatherings. Now, we are in the original containment zone here in new rochelle. The area where the National Guard was stationed just three months ago. Now we know that this area is openi opening, contact tracers were trained over the weekend. But its not just here. Its a total of seven counties in new york that can reopen and begin phase i, john, and that includes manufacturing construction and retail pickup. Its been a long time coming. Its taken a lot of hard work in these regions with social distancing really at a premium there. Brynn gingras, thank you very much for being with us. Joining us now, dr. Juan duewa at john hopkins allchildrens hospital. And cnn analyst margaret talov. Ip i want to show you the pictures of people we saw all weekend long partying, close to each other, all over each other at the ozarks, there was this pool party. And now you have local Health Officials in the kansas city area and the st. Louis area saying, look, you know, if you live in our counties and went down to this pool party, we want you to selfquarantine, because you could be at risk right now. When you see these pictures and when you know things like this were happening all over the country, doctor, what can be done at this point . It does seem like pandoras box has been opened and people are just out doing their thing, so how does one control or try to mitigate possible damage here . Well, i think we just need to keep getting the message out there, that this virus is not gone. And that avoiding of social distancing is just giving the coronavirus more opportunities to very quickly spread to other people. And in areas that have already seen maybe a decrease in the number of daily cases, theyre going to start seeing an increase in a few weeks. But doctor, isnt it true in the terms of the super spreader events, they were all indoors. And so isnt it harder to spread the virus outdoors . I dont want to give everybody a license to run out and have a Pool Party Like that, but is it exponentially harder to spread it outdoors than it is indoors . It depends on the circumstances and the conditions when youre outcoordoors. If youre outdoors and going for a walk in the park where youre not clustering with other people, chances are someone who is coughing out the virus will have those particles from their breath dissipate very quickly and blown away by the wind. But if youre in close proximity to other people and you are staying in close proximity, a little bit of a breeze and youre downwind of the person who coughs and is infected, that will blow right into your face with your next breath, youre inhaling virus. So it depends on how close you are to these other people and how long you are close to them that increases your risk. It seems to me that sharing a raft or perhaps sharing a margarita with somebody doesnt really matter whether youre inside or matter. Why do i hear a tinge of envy every time you describe this party . Look, i have no desire to be near that many people ever, let alone during a pandemic. But margaret, theres another what i consider nondebate going on this morning, and i think its truly fascinating. So former Vice President joe biden went to a memorial day observance in yesterday and he was wearing a mask. Weve seen pictures of it. Perhaps we can see it again. You can see them there in the black mask. The president and his wife went to services and they were not wearing a mask. Whats interesting to me, brit hume of fox tv put out a tweet of a picture of joe biden that said, this might explain why trump doesnt like to wear a mask in public. Im not sure i get it. I really am not. And the president retweeted this. This is a huge majority issue in the country. 64 of americans say that we should all be required to wear masks in public. 67 say the president should be required to wear a mask in public. And the cdc says you should wear a mask in public. So whos owning whom here . The president retweeted a picture of joe biden doing something that is wildly popular among the american people. Good morning, john. And you asked, what can we do collectively as a country, right . To try to minimize the spread of this. And wearing the masks is one of those things. Not only because it creates a barrier, but because it creates a psychological barrier, as well. When you see someone wearing a mask, youre not going to get right up in their face. So, youre right, there is wide bipartisan support for this. Our own weekly polling with ipsos shows this, but theres also a partisan split. Sympathies an issue that unifies democrats and to some extent divides republicans. While most americans are Wearing Maskses, the support for this is softer among republicans and the support for this is softer in rural areas as opposed to urban and suburban areas. So its like yet become another political rorschach test. And its a dangerous one, its a divisive one, but the president feels that wearing a mask kind of looks silly or projects weakness and that in situations at least in his case, where he says hes been tested, hes okay, he has sought not to wear these in public. Well see on wednesday when we see him, you know, in florida. But for biden, that campaigns feeling is that at least among their base, its not only okay to wear a mask, but there is a wide expectation that he should to send a signal about how others should behavior. But here again, dr. Dumois, there is a distinction. President trump didnt wear a mask inside, he went into a crowded ford plant in michigan where it is the law, the state law, to wear a mask. And it was the ford companys policy that everyone who goes indoors, all visitors, everyone wears a mask. And he was within 6 feet of people. So thats theres no question there that you should be modeling the Good Behavior and lawful behavior of wearing a mask. But outdoors, where Vice President joe biden was, that is still, as you just said, thats sort of peoples judgment. And you have to and this is where people get confused, because before you head out the door, you try to figure out if youre going for your run or if youre going to a veterans memorial, if youre going to be within 6 feet of someone else. Yeah, i think that it is incumbent on highly visible politicians and celebrities to show a good example. And it does not make a good example if youre indoors, closely in groups of people and not wearing a mask. It just gives the message that its not important. And i think that it is. Look, i wish the words on our screen said, trump retweets picture of joe biden doing something wildly popular. Or trump retweets picture of joe biden doing something that the cdc recommends that everyone do. And 40 of republicans are supportive of Wearing Masks in public. There arent many issues that joe biden can back that have 40 republican approval here. So ill leave the medicine to the doctors here, but the politics to me are fairly clear.

Stock futures are surging. They are up nearly 500 points, ahead of the open, thanks to optimism about another potential coronavirus vaccine. The american Biotech Company, novavax announces that it is starting human trials. Elizabeth cohen joins us now with details. What do we know, elizabeth . Alisyn, the word that keeps coming to my mind is preliminary. This is preliminary data, preliminary information. Still, important that a tenth vaccine maker is moving into this field. As you said, the company is called novavax, theyre based in the United States and theyre starting a round of preliminary investigation, if you will, with 130 study subjects. They said that they plan to vaccinate their first volunteer in australia. Thats where theyre doing their trials, last night. Again,th theyll go on to do 13 people. They hope by july to have some information about how these 130 people did. Did the vaccine seem to illicit an immune response, and also, is it safe . So this is the tenth vaccine to join the world scene in human clinical trials. And lets take a look at what is going around, going on around the world. Ten worldwide, this is the fourth in the United States. There are also five in china. One in the uk, and 114 in preclinical stages, meaning they are not in human clinical trials, theyre in the lab, theyre doing work with animals. You will notice that not all of these will turn into real vaccines that you and i and the world will get. And thats okay. We expect them to start with a lot. The best ones will hopefully succeed. We hope to have several vaccines. Some might work well for certain groups, young groups, old People Better than others. John . Joining me now is william hassletine, hes now the chair and president of Access Health international. Professor, it is always an education to have you on. Lets talk about novavax, just as a peg for what you have been focused on the last few days. Novavax is the tenth company now to move forward in these vaccine trials. You look at this as a broad subject and say, you know, we need to approach all of this with more caution. Why . The question that most people ask me and will ask to themselves about the vaccine is, when will we have it . The question a scientists or doctors ask is if we will have it. At this point, its not clear that the answer to if is definite. Its not clear that we will definitely have one of these vaccines. And the reason is, has to do with the virus itself. Has to do with the nature of the population thats being vaccinated. Let me point out something thats really obvious. The people who need this vaccine the most are old. Those over 60, 70, 80. Those are exactly the people that have a very hard time making a good response to any vaccine. Whether its a live vaccine, a killed vaccine, a vaccine in a new kind of particle, the novavax people are proposing. Thats the first question. The second question is, we already know from primate studies, nonhuman primate studies and from some very preliminary evidence from the first human trial where we have some data thats been published is that were not sure what kind of immune response these vaccines are making. Is it really a good one . Will it really protect . Or will it partially protect . And if it partially protects, then whats the policy . So my view of all of this is, we know how to control the virus without a drug and without a vaccine. Thats happened all over the east, including australia and new zealand. Lets use the tools we have now and hope for a better future. But that hope is only a hope. You talked about the various challenges here. Number one, for whom will the vaccine be most effective . Dealing with the older population. And then you mentioned something that has to do with the virus itself. We know these are coronaviruses. And we have years and years of experiences with coronaviruses. About one third of all the colds you get every year are coronaviruses. And many, many years ago, people did experiments where they infected people, volunteers, to get a cold. Not a serious disease. To get a cold and then a year later came back and used the same virus to see if they were protected and they werent. We also know from the study of the blood in the serum and the antibodies in people who recover from covid, from this disease, is that the antibody response is not strong, its weak. And only a few people out of the whole group make enough antibody that can stop the virus, even in the test tube, much less in real life. If they are producing neutralizing antibodies, if they are producing neutralizing antibodies, would some of the press releases on these studies and i know theres a distinction between studies and press releases but some of these companies have said that i have seen evidence of producing neutralizing antibodies, is that a positive sign . Or might that be limited, too . Its not a negative sign, let me put it that way, but however, its not a high level of neutralization. And it doesnt protect the monkeys from getting infected in the nose. In fact, if you look at the oxford trial, every single one of the vaccinated animals were actually infected. Its true that the virus levels in the lungs were lower, but what about the virus levels in the nasal passages that transmit the viruses . And this virus doesnt just attack the lung, it attacks the vascular system, it attacks the kidney. What else wont be protected by these vaccines . So there are many deep questions, long questions. And this is not going to be over soon. This is a final important topic we didnt talk about, which is safety. When youre giving a vaccine to people, youre giving it to healthy people. And you may be giving, in this case, to hundreds of millions, even a billion or more healthy people. It has to be really safe. How many people do you have to test the vaccine in before you know its safe to give to children, adults, and maybe a billion or more of them . We havent ever had really drugs like that, but w
