it's been really, really great. this is the last night that we'll be "cnn tonight" with don lemon. so i appreciate all the years of "cnn tonight" with don lemon, but changes are coming, and i will fill you in. the fifth straight night of deadly conflict. israelis and palestinians brace for what could be another day filled with tragedy. we're live in the region. and the great unmasking. the latest on which stores will and won't require you to mask up. also -- >> i woke up with an irish accent, and i've never been to ireland before. >> imagine waking up after surgery with a completely different accent. the rare circumstance that has turned this woman into a social media sensation.

hello and welcome to our viewers here in the united states and all around the world. appreciate your company. i'm michael holmes. this is "cnn newsroom." ♪ as the death toll climbs in gaza from israeli air strikes and artillery, deadly violence spreading to the west bank. at least ten palestinians reportedly killed friday. many others were injured as they clashed with israeli soldiers in the west bank. we'll have more on that in just a moment. now, israel's bombardment of gaza has been going on around the clock. the palestinian health ministry says at least 126 palestinians have been killed.

dozens of children since this conflict began. eight israelis have been killed by rockets fired from gaza, most of them being destroyed by israel's iron dome system. but some have slipped through with deadly effect. we begin our coverage with the escalating violence now erupting outside of gaza. cnn's ben wedeman was in bethlehem when the clashes there exploded. >> reporter: and now the west bank. we're in bethlehem. a new generation of palestinians has taken to the barricades, facing a new generation of israeli soldiers. friday saw the most intense confrontations in years between palestinian youth and israeli security forces throughout the west bank. palestinian officials reported the highest daily death toll

here in years with hundreds injured. somebody's just been wounded here. in fact, they're coming our way. let's step aside. it's a woman who's been hit. countless are the stones thrown here over the years. beyond calculation the number of tires burned. countless the tear gas canisters that have rained down on this street. the israeli military is shooting volley after volley of tear gas trying to break up this protest, which is just one of the protests going on across the west bank. the message on this day one of solidarity with their fellow palestinians in jerusalem, gaza and inside israel. if one of us is wounded, we are with them, says this young man, who declined to give his name. we support them as if the entire

palestinian people were wounded. b this bethlehem resident took part in his youth and shared his story. >> we have rights and we are not going anywhere and we'll continue until we have our independent states. >> reporter: the woes of this troubled land passed from father to son. ben wedeman, cnn, bethlehem on the west bank. >> a journalist joins me live from tel aviv. we saw there the violence in the west bank. there will be funerals for those people. it is also the day which is traditionally a day of protest anyway, probably made worse by the sort of situation there. what are we expecting today in terms of the violence and escalation?

>> reporter: well, that's right. over the past week, we've seen tensions and clashes in jerusalem, open warfare in gaza, intercommunal riots and clashes on the streets of israel between arab and jewish citizens of the country. through it all the west bank had remained relatively calm and relatively stable until yesterday and the clashes and loss of life that you mentioned. the real fear today, may 15th, it's a major political milestone in the palestinian calendar where the creation of the state of israel in 1948 is marked by the palestinians, a day of catastrophe. usually demonstrations and marches and clashes take place. g given the events of yesterday and the past week, the fear on the ground is things will only escalate, especially today. >> you touched on this, and let's revisit it. a particularly worrying aspect of what's been happening is this intercommunal violence in israel's mixed cities where jews

and arabs live together. highly unusual. how concerning that development in the broader picture? >> reporter: well, for israel, it's had rounds of conflict with gaza before. it's had tensions and unrest in jerusalem and the west bank. but really the unrest and the rioting and the intercommunal violence in recent days is unprecedented. israeli officials say it outright, and you can feel it on the streets. i'm standing in a mixed neighborhood in tel aviv on a saturday morning. usually you'd have visitors and tourists coming here. the beach is several feet away. but it's fairly empty. shops are closed, and police cars patrol sporadically. you can feel the tension in the air. there were violent incidents inside ja fa earlier -- rather last night. clashes and intercommunal riots spread to northern israel last night as well. so it's continuing.

like i said, unprecedented both in scale and in the ferocity of what we're seeing here on the ground inside israel. >> and just quickly, talk about the challenges dealing with gaza, of course, but the west bank as we've just been talking about, the towns, the israeli/arab towns, and there's been incidents at the borders with jordan and lebanon, missiles from syria. how stretched thin are these security forces? >> reporter: the concern is that they're rather stretched thin. we should remember that earlier this week, to quell the intercommunal rioting in the central israeli city, the government redeployed about nine companies of border police precisely from the west bank into israel in order to bolster the police there. so it's an open question whether the israeli security forces have enough forces in the west bank on top of the open warfare in gaza and the obvious tensions in

the north that you mentioned on the border with syria. and lebanon today we all know will be a major test of the idf capabilities, and the hope at least on the part of israel is that they're up to the challenge. >> all right. really appreciate it. neri s neri zilber. thank you so much. right across the middle east, people concerned about the violence are expressing it in the streets as we've just been discussing. in jordan, riot police had to disperse hundreds of protesters when they charged towards the israeli border. and we're seeing similar pro-palestinian demonstrations in many middle eastern countries. soldiers in lebanon had to stop protesters from crossing into israel following a rally in support of palestinians organized by hezbollah. let's bring in cnn's salma abdulazeez who is live in beirut. we were just talking about this. explain what it means there too,

the day when palestinians pro-at the time the creation of israel. the events adding to the emotions of that throughout the region. >> reporter: absolutely, michael. this is a key day that commemorates the hundreds of thousands of palestinians that were displaced in 1948 around the conflict when the state of israel was founded. those hundreds of thousands of refugees created during that crisis, their descendants now number in the millions. they are spread out, as you would expect, of course, across the region, in syria, in jordan, and here in lebanon as well. so you're seeing strong calls for demonstrations and protests on this day. there is a protest called in southern lebanon here, not just by hezbollah, of course, the prominent militant and political faction that operates in that area, but also by other political factions, those that sometimes even rival hezbollah. everyone unified in calling for this protest. as you mentioned, there's concern it could turn violent

because yesterday there was a 21-year-old lebanese man while storming that fence, the lebanese-israeli border fence, he died of wounds sustained after the israeli military fired a rocket. so there's fears there could be more blood-letting and more blood-letting leads to more tensions and more confrontations. alongside these very traditional demonstrations that you would expect, the rhetoric that we've heard from this region for decades, you're also seeing a really big shift in the region, michael. you have several countries trying to normalize relationships with israel. take, for example, the uae, the united arab emirates. just a year ago they signed a deal to normalize relationships with israel. not just them. morocco, bahrain, saudi arabia very quietly behind closed doors speaking as well to israeli officials. so you're hearing very muted criticism at a time like this. it's a real test for these gulf states, michael, because the argument in signing these deals with israel, in signing something like the abraham

accords, was that it would give them more influence on the negotiating table when something happens. that something happening is right now. as mediations start, the question is will these countries actually have the ability to really influence, to really move things on the ground, to really change the reality of the bombardment that people in gaza are living under, or is this simply empty words, michael? >> yeah. it's not just gaza and the west bank. this is a regional issue now. salma, appreciate it. the u.n. security council set to meet on sunday to discuss the ongoing conflict. you might recall that a similar meeting scheduled for friday was actually blocked by the u.s. the white house on friday explaining how the u.s. views the rising death toll in gaza and israel and what should be done about it. >> the president believes that israel has a right to self-defense. obviously just if we take a step back and remove ourselves for a moment, which i know is hard to do, from the politics, clearly

what's happening on the ground, the loss of life, the loss of children's lives, the loss of family members' lives, whether it's palestinian lives or israeli lives, is incredibly tragic. it's horrific to watch. that is certainly why our focus is on de-escalating what is happening on the ground. >> we are seeing images of solidarity around the world for both sides of this grueling and devastating conflict. a mosque in brazil, we'll show you there, illuminated its dome with both the brazilian and palestinian flags, and with it a message reading "free and sovereign palestine." in ukraine, an israeli flag flew in the skies of kiev attached to a drone. the company behind this gesture says it wanted to express its condolences and show support for the people of israel. still to come here on "cnn newsroom," mask on or mask off?

the cdc issues new advice for vaccinated americans, but not everybody is onboard with the latest guidance. meanwhile, in japan, lots of pushback against hosting the olympic games this year, including from one of the country's top ceos. >> do you think it's still possible that they could be canceled? >> i think everything is possible. ral smelling fragrances, day after day... ...for up to 60 days. give us one plug for freshness that lasts.

people who feel, which they should now based on the data, that is safe for them not only outdoors but indoors, they should feel comfortable in not wearing a mask. >> despite dr. fauci insisting that new cdc mask guidelines are safe, the abrupt change has sparked widespread confusion. the cdc now says fully vaccinated americans do not need to wear face coverings in most settings. many states have responded by lifting their mask mandates. but the rules still vary nationwide. starbucks says face coverings will be optional for vaccinated customers starting monday unless a local requirement is in place. and universal orlando says you can ditch the mask outside, but

you have to wear one indoors. cnn's nick watt with more on a patchwork of rules. >> reporter: the percentage of covid-19 tests coming back positive has never been lower than it's been these past few days, ever. that's big. so is this. >> if you are fully vaccinated, you no longer need to wear a mask. >> reporter: too soon? >> this change was really abrupt. the cdc went from zero to 100 overnight. >> reporter: let's break it down. just the fully vaccinated, so just over one-third of the population. >> these decisions are going to have to be made at the local level. >> reporter: take hawaii. for now -- >> my mask mandate continues to be enforced. everyone must wear their masks indoors. >> reporter: minnesota's mask mandate already no more. >> if you're going into a business where folks are unmasked, you know that they're vaccinated, it's a safe thing to do. >> reporter: but how do you know they're vaccinated?

>> this really is the honor system. so i'm still going to wear a mask if i'm in a public indoor place. >> reporter: some school districts already dropped mandates. >> zero. no one wears mask. i haven't seen one mask. >> it's pretty sweet, pretty dope. we got rid of it. >> reporter: chad is now eligible for a vaccine. but, remember, younger kids still are not. the cdc, we're told, struggling to convince vaccine hesitant republicans. it's kind of a mess to figure out with this particular audience what resonates with them, said one source, because they see vaccines as taking away their freedom. does stuff like this actually help? >> fans that come out tomorrow, and if they're either tested or get the vaccination, they'll be able to take two laps around the talladega supersp speedway. >> nick watt reporting there. the race between the virus and the vaccines may be about to become a great deal tighter. that's what the british prime minister boris johnson says

issuing a stark warning after cases of the indian covid variant doubled in england in a week. he said the government will accelerate its vaccination rollout in response. england due to enter the next phase of reopening on monday. mr. johnson saying that will go ahead as planned. for more on all of this, let's bring in cnn's phil black in london. how serious the concerns and wo worries that the variant could impact reopening plans? >> reporter: the truth is no one knows precisely how worried we should be about this new variant just yet. the numbers are still small, around 1,300 confirmed cases, but they're increasing quickly. the government and scientific advisers have said, yes, it is more transmissible, but they don't know how much more transmissible, nor do they know how much more likely, if at all, it will result in more serious disease and therefore death. and they don't know what it means for the effectiveness of existing vaccines. these are big questions which

the government believes will be answered in the coming weeks as the information flows through, as they watch what this variant is doing out in the population. so for now, the uk is continuing on what it calls its roadmap to reopening. the next big step happens monday. that is when indoor mixing returns. it's a big, risky step in itself. people will be able to get together in their homes, in restaurants, bars, although with some size limitations. the next step, about five weeks later, that's the really big one. that's essentially the lifting of all pandemic restrictions, and that is the step that the prime minister has warned could be delayed or could be in some doubt depending upon what this variant does in the coming weeks. now, the prime minister points out there are really good reasons not to panic about this at the moment because the uk is in such a different situation now compared to when previous surges have taken place. that's because of the vaccination program. there is so much more immunity out in the population that it should, in theory, be much

harder for the variant hopefully to spread. but there are still concerns that this could cause trouble if it is significantly more transmissible. that could still result in a surge because vaccines aren't perfect. they don't provide absolute protection, and there are still large parts of the population that are not protected by a vaccine, notably young people. it means you could still see a spike in cases. if that happens and the key indicator will be, do you see a spike in hospital admissions, that's what the government, its scientists will be looking for. if you don't see that, that means the vaccines are still doing their job, protecting the vulnerable and stopping incidences of serious disease. that's essentially the scenario at the moment that the government is betting on in choosing to continue with its process of reopening english society. >> all right. phil, good to see you. taiwan is strengthening

coronavirus restrictions in two of its biggest cities after setting a single-day record for local cases. the island reporting 29 new domestic cases on friday, the most locally transmitted infections in a single day since the pandemic began. masks now required in public in taipei and in new taipei. and indoor gatherings of more than five people are banned. the restrictions will be in place through may 28. now, the tokyo olympic games are scheduled to start in just a couple of months from now, but coronavirus still spreading rapidly in japan. protesters, doctors, even business leaders in japan say holding the games this year is flat-out dangerous. selina wang joins me now from tokyo. growing corporate opposition and concern about the olympics in addition to the public worries. >> reporter: michael, that's exactly right. we're about ten weeks out now and the mood on the ground is really changing.

you're seeing the public opposition to the games really snowball. we've seen the public polls for many months now show the majority of the people here in japan think the games should be canceled. but now even high-profile voices across a variety of industries are coming out. i sat down with the ceo of rakuten, which is a tech giant in japan. it's often referred to as the amazon of this come. he's one of the most prominent executives in japan and he tells me he's urging the government to cancel the games. the comments he told me are some of the strongest public critical comments against these games from any corporate leader in japan. take a listen here. >> do you think japan should host the olympics this summer considering rising covid-19 cases in japan and its strained medical system? >> i have been very, very straightforward about this issue and the fact that we have so late for the vaccination, it's dangerous to host the big

international event from all over the world. so the risk is too big, and, you know, i'm against having the tokyo olympics this year. >> do you think it's still possible that they could be canceled? >> i think everything is possible, right? i think, you know, i see -- i talk with government officials from other countries, and many people is not really supportive of hosting tokyo olympics this year. >> why do you think the government has been so forceful in its determination that they will still go ahead despite the public opposition, including from business leaders like yourself? >> i don't know to be honest. i call it a suicide mission to be very honest, and it should stop. i'm trying to convince them, but not successful so far. >> reporter: michael, i also asked the rakuten ceo how he

would grade the japanese government's handling of covid-19. he said he'd rate it a 2 out of 10. japan so far has only fully vaccinated about 1% of its population, and concerns have also been echoed by the toyota company, which is a top olympic sponsor. they said their concern about growing frustration against the games. an online petition here in japan received more than 350,000 signatures to cancel the olympics in just nine days. a doctors union said that it is impossible to hold the games safely, saying they could still become a superspreader event even without any spectators. meanwhile you have covid-19 cases continuing to surge in japan. the state of emergency has now been expanded to three more prefectures. despite all of these concerns, the ioc and japanese government have been portraying absolute confidence that these games will be held as planned. >> less than 1% vaccination rate, wow. selina wang in tokyo, appreciate it. interesting stuff there.

welcome back to "cnn newsroom," everyone. i'm michael holmes. on capitol hill, a trump loyalist now holding a key position in the republican party's house leadership. while some lawmakers are trying to rewrite history about january's capitol insurrection. cnn congressional correspondent ryan nobles reports from washington. >> reporter: the house republican conference overwhelmingly picking new york

congresswoman elise stefanik as their new conference chair and presenting a united front. >> listen, the republican party is a big tent party and my district is the story of the growth of the republican party. >> reporter: but it may not be that easy. >> there have been things worse than people without any firearms coming into a building. >> reporter: rank and file hard-right members are now attempting to rewrite the history of what happened during the january 6th insurrection. texas congressman louie gohmert did so friday from the house floor. >> there's no doubt people came here on january 6th to cause trouble. most did not come here to cause trouble. most came here to protest. >> reporter: this despite harrowing stories of violence and chaos from that day that continue to emerge from police officers. some of whom were beaten and had their own weapons turned on them. >> i believe that violent group

would have killed individuals inside of the capitol complex. >> for people to contradict that, it's -- it's insulting. it's a slap in the face. >> reporter: this growing move to rewrite history comes on the same day a bipartisan deal was hatched to form an independent commission to look into what went wrong on that day. the commission will be evenly split between republicans and democrats. they will have equal subpoena power, and the scope will be limited to january 6th and the events that led to the attack. while the negotiations were bipartisan, the top house republican, kevin mccarthy, has yet to sign off. but democrats say that won't be a problem. >> so we tried to take the politics out of it because the public deserves nothing less. >> reporter: with a handful of far-right republicans painting a different picture of what happened that day, drawing a clear conclusion as to what went wrong is now imperative. liz cheney, who lost her

leadership post for telling the truth about the election, said gop leaders cannot ignore this trend. >> it's very important for people to understand that the ongoing danger of a former president attempting to undermine the system in the way he is, and as republicans we have a particular responsibility to stand up against that. >> reporter: but the conservative provocateurs are only getting louder. >> we're going to visit alexandria ocasio-cortez, crazy eyes. >> reporter: new video uncovered by the cnn kfile team shows marjorie taylor greene before she was elected to congress taunting alexandria ocasio-cortez outside her office door. this after green confronted ocasio cortes outside the house chamber. aoc saying that mtg needs professional help. >> i'm concerned about her perceptions of reality. >> reporter: despite all this ongoing tension between republicans and democrats, the house speaker nancy pelosi is prepared to move forward with plans to form this bipartisan commission to look into the

events of january 6th. she says she will bring a bill to the house floor as soon as next week. this despite the fact that the house minority leader kevin mccarthy has yet to endorse the proposal. ryan nobles, cnn, on capitol hill. >> and we just saw there a little bit of jake tapper's interview with u.s. house republican liz cheney here on cnn after she was ousted from her leadership role. she's been highly critical of former president trump and his false insistence that the 2020 election was stolen. here's a little more of that interview. >> what is it like standing up for what seems, from my perspective, to be just kind of basic decency, law and order, constitutionality and be shunned by house republicans? it looks weird from where i sit. >> well, you're not a house republican. >> right. true. >> listen, i think that to me,

it's -- it's very clear what is required here, and it's not -- you know, some people say, well, it's courageous. i don't think of it that way. i think, you know, you've written about men in particular who have real courage. this is not landing on omaha beach or being at a foreign operating base in afghanistan. this is duty, and it's about truth. and we've had a collapse of truth in this country. we've, you know, seen an evolution of, you know, general situation where conspiracy theories are rampant, where people -- good people in a lot of instances, you know, have been misled and believe things that are not true. and so i think that we all have an obligation to make sure we're doing everything we can to convey the truth, to stand for the truth, and to stand for the constitution and our obligations. >> one of the things that i hear that i think a lot of people in the media and maybe the public are missing is -- and you said this the other day.

this isn't just about the past. this isn't just about the lie before the insurrection and the lie since the insurrection. it sounds to me like you're saying trump tried to steal the election once, and he and his supporters, his acolytes, they're going to try to do it again. >> well, i think he is currently attempting to convince people that the election was stolen. he uses words like it was rigged. every day now we see another release out from him, and it's really dangerous. you know, what it does is it undermines people's confidence in our system, and ultimately we've got to have respect for the rule of law. we had 60 state and federal courts that heard his claims, rejected those claims. the electoral college met. that's the end of it. now, of course, in this instance it wasn't. but we've seen what he's capable of, and he hasn't expressed any remorse or regret for january 6th, and i think it's very important for people to understand that the ongoing danger of a former president attempting to undermine the

system in the way he is. and as republicans, we have a particular responsibility to stand up against that. >> but are you worried that he's going to try in 2024 and having now purged people like you, trying to purge people like secretary of state raffensperger in georgia, et cetera, et cetera, this time he might succeed? >> he won't succeed. he may try, but he won't succeed. >> and liz cheney also spoke to abc news, saying that she regrets voting for donald trump in 2020. and that is not the only issue confronting the republican party. a former associate of gop congressman matt gaetz has reached a plea deal with federal prosecutors over sex trafficking charges. cnn's paula reid explains why that might mean trouble for matt gaetz. >> reporter: former florida tax collector joel greenberg has struck a deal with prosecutors where he will cooperate in ongoing federal investigations and plead guilty to six criminal charges, including sex trafficking of a minor.

greenberg's close associate, congressman matt gaetz, is not mentioned anywhere in this 80-page plea agreement. congressman gaetz has not been charged with a crime, and he has denied any wrongdoing. but cnn news learned he is under investigation for possible prostitution, sex trafficking, and having sex with a minor. and as part of this plea agreement, joel greenberg has to cooperate fully in any ongoing federal investigations. now, one of the most significant parts of this plea agreement is where greenberg says that he plans to admit in court that he introduced a child to other adult men who engaged in commercial sex acts with that minor. now, depending on who he is referring to there, that could potentially cause trouble for congressman gaetz. cnn has previously reported that over the past year, greenberg has provided investigators with information about how he and gaetz exchanged money and gifts for sex with women.

so just because gaetz isn't mentioned in this plea agreement doesn't mean that greenberg hasn't shared any information. now, cnn has also previously viewed receipts where gaetz and greenberg paid at least one woman following a so-called sex party. and in this plea agreement, greenberg details exactly how he used to pay women over electronic apps like venmo. he admits to spending $70,000 in 150 transactions to pay for sex. now, we could learn potentially more about this plea agreement when mr. greenberg appears in federal court in orlando on monday. paula reid, cnn, washington. we're going to tick a quick break. when we come back, younger teens in the u.s. now have access to a coronavirus vaccine for the first time. but for that to happen, the drug had to be tested. coming up, we'll introduce you to some of the kids who helped make the vaccine possible for their classmates. we'll be right back.

a critical u.s. shipping route is at least partially open. you can see the first vessel there passing under the interstate 40 bridge which spans the mississippi river at memphis, tennessee, and connects three states. river traffic was allowed to resume friday after days of safety checks. the vital bridge was shut down last week after a crack was discovered in a steel beam. hundreds of barges have been waiting to pass underneath it. the bridge is still not open to cars and trucks, though. they've got to fix it. nearly 2.5 million children in the u.s. have received at least one dose of the pfizer/biontech covid-19 vaccine. up until a few days ago, it was only available to kids 16 and 17 years old. but that changed on monday when the food and drug administration extended authorization of the vaccine to children as young as 12. cnn's chief medical

correspondent sanjay gupta talks to some of the children and teens who were first in line to get the vaccine. >> reporter: this is 15-year-old ben droppic. he's about to get the covid-19 vaccine as part of a clinical trial. >> ready? >> mm-hmm. >> reporter: thanks to ben and about 2,000 other teens like him, 12 to 15-year-olds all across the united states are now able to get a covid-19 vaccine. >> one, two, three. >> this is trying to beat the virus, trying to get everything back to normal. >> the kids have been leading the charge on a lot of this. >> reporter: dr. robert frank has been researching vaccines on kids for 40 years. he now oversees covid-19 vaccine trials in kids at cincinnati children's hospital. >> one of the things that people have said is that teenagers, they only care about themselves, and they're just looking out for themselves. and i have found that to be totally wrong. >> reporter: they've also found another piece of good news. just one month after getting the second dose, pfizer's trials

found that teens aged 12 to 15 had even higher levels of antibodies than 16 to 25-year-olds who had also received the shots, making them far less likely to get sick. >> 18 cases of covid in the 1,500 adolescents that had placebo and zero in the group that got vaccine. >> reporter: since the pandemic began, the cdc estimates more than 26 million children have been infected with covid-19, and around 3% have been hospitalized. the agency says kids under 18 make up around 23% of all cases but represent just 0.1% of all the deaths. the agency has found more than 3,700 children have developed a hyperimmune response to the virus, known as misc. >> i imagine that a lot of parents will say, look, i don't think that my kid or kids in general are that at risk of getting sick in the first place. what is the real reason that we need to get kids vaccinated? >> so they have a runny nose,

they have a cough, they don't seem like they're that sick. mom or dad is not going to take them to the doctor, but they actually have covid. and they end up then going to grandma and grandpa and accidentally infecting them or others, and those people get very sick. and the other thing, i guess, to remember is that we have 75 million people under 18 years of age in the united states. if we don't immunize that group, that's going to leave a big population that's susceptible to the virus. >> reporter: now, remember in order to stop transmission, we want to reach herd or community immunity, and you get there through a combination of vaccination as well as antibodies from previous infections. the threshold of community immunity is based on how contagious the virus is. for example, measles, which is really contagious, requires around 90% herd immunity. for the novel coronavirus, somewhere around 70% to 85%. the fda's expanded authorization

for 12 to 15-year-olds now makes 85% of the u.s. population eligible for a shot. but even then, surveys show about 1 in 8 adults aren't planning on getting the vaccine. about 1 in 5 parents say they won't vaccinate their kids either, which is why the focus is now on going even younger. trials have now begun in kids like 7-year-old naomi. >> naomi, after seeing a friend of our family, said that she wanted to do it. it would give me a lot of peace of mind because i know that she'll be protected. >> one, two, three. really proud of you. >> i'm going to tell them that they should get the vaccine so they can protect themselves, their family, and everyone around them so that -- and that would be a great way to keep the world safe.
