united states and all around the world, we have reports from rome, berlin, the white house and tokyo. this is "early start," i'm laura jarrett. >> good morning, i'm christine romans. we begin in europe, it's cheaper, simpler to deliver and is being pulled off the market, some countries in the last few minutes halting use of the astrazeneca covid vaccine after a small number of patients experienced blood clots. it's another blow to the eu's sluggish vaccine rollout. in vaccine is not authorized in the u.s. yet but it is being counted on to fight the uk variant spreading around the world. >> all this comes at a really difficult time. a third wave of infections is sweeping across europe and forcing renewed restrictions, hospitalizations on the rise in france, germany seeing a spike in cases and italians back under lockdown. that's where cnn's melissa bell is live for us this morning, she's in rome. melissa, good morning. what can you tell us? >> reporter: good morning, lawyer rachlt it was even as italy or parts ofity la, more than half of its regions entered that new lockdown that the news came that italy was growing that growing list list of countries pausing the astrazeneca vaccine. now, we know that the company itself astrazeneca says, look, 17 million doses have now been administered in the uk and in the eu and there have been just over 30 issues of patients who may have gone on to develop blood clots. the company says, look, this is what you would find in the average population or less. i think what began to change minds is there had been a divide between those countries in europe beginning to pause the rollout and germany and france, for instance, that were defending its continued use. then they changed their minds yesterday. i think what's behind that was not so much the question of the numbers of people who had begun to develop blood clots but more this news from denmark that one of the people who had died was found to have unusual symptoms before she did. i think that set off a bunch of alarm bells. the european medicines agency says that the vaccine rollout should continue, it's continued to defend its use, but it is investigating, laura, and until we get those results from the european regulatory body on thursday it's very difficult to see that this debate is going to go away. we happen to be at a vaccination center just outside of rome when the news came, it was delivering the astrazeneca vaccine, it stopped delivering it when the news came. people were turned away. we asked a bunch of them, look, if this advice changes, if the science shows that there is, in fact, no danger, will you come back and take it? all of them said no. i think this is the final irony of this. it was partly because of the natural vaccine hesitancy of european populations that so many of those regulatory bodies decided, laura, that they would pause as a matter of abundant precaution the rollout this have vaccine but that decision almost whatever the science says at this stage is only likely to make that worse. >> this is not helping public trust in people who already might have had worries about the vaccine, as you mentioned, people saying they would not come back is certainly revelatory. thank you for saying on top of this for us. so that vaccine, that astrazeneca vaccine, has not been considered yet for emergency use in the united states. that is expected to happen next month. but there are some doses being produced and packed in the u.s. and mexico wants them. the vaccine is approved in mexico and the country's deputy foreign minister says the u.s. has been asked to share. mexico's president says his country is close to reaching two vaccine deals. more details are expected later today. the biden administration is race to go prepare for another potential surge of coronavirus and for the very first time plans are being drawn up to flood emerging hot spots with vaccines. jasmine wright is live at the white house this morning. talk to me. what exactly is being considered here? how would this work? >> reporter: well, look, laura, the white house, as you said, it's trying to head off any potential fourth surge so they are making plans, really trying to prepare for it ahead of time and that includes investing billions of dollars and a plan to ship vaccines to those emerging hot spots that they have identified through data working with those community leaders and elected officials to make sure that those areas are prepared for any type of uptick because honestly the white house feels like they are in a good place right now, we know that they identified july 4th as a time when we can get back to normalcy and they want to keep along this trajectory. this is something that we did not see from the previous administration who oftentimes responded to those surges after they started happening. now, laura, this comes at a time when the white house is grappling with the influence of former president trump and that he has over the folks that voted for him, really those republican voters who now are more hesitant to take that vaccine and whether or not former president trump is doing enough to get them to get those shots in their arms. now, the white house is kind of taking a line while they would welcome president trump's influence in getting more folks to get their vaccines, they likely are not going to ask him. president biden yesterday in his remarks address it had and instead called on leaders in those communities to pick up the slack. >> they say the thing that has more impact than anything trump would say to the maga folks is what the local doctor, what the local preachers, what the local people in the community say. so i urge, i urge all local docs and ministers and priests to talk about why, why it's important to get that vaccine. >> reporter: now, laura, today we will see president trump make his debut on that help is here tour in pennsylvania where he will visit a small business to talk about how small businesses across the country can benefit from this bill. >> president biden obviously hitting the road, trying to make a real push. they say they're not selling t but they are trying to explain what is in that bill. thanks so much, jasmine. explain, promote, publicize, the white house reaffirming president biden's campaign promise now to raise taxes on the rich. >> his priority and focus has always been on people paying their fair share. there is a shared view that those at the top are not doing their part. obviously that corporations could be pay higher taxes. >> candidate biden pledged tax hikes on the healthy and corporations by reversing some of president trump's 2017 tax cuts. he promised to never raise taxes on anyone making $400,000 a year or less. the treasury secretary janet yellen said sunday tax hikes could be used to control the deficit, but vice president kamala harris did not confirm these reports they would help pay for future plans to boost economic growth. >> we haven't really figured out what the next phase is going to be to be honest with you and we are going to make those decisiones. >> the next phase includes investments in infrastructure, clean energy, education, the biden agenda here, kwt he is how to pay for it, with more borrowing, tax increases or both. a watchdog found the irs is failing to hold wealthy americans accountable for tax evasion. the treasury inspector general says millionaires have dodged $2.4 billion in back taxes. the report warns this leads to the belief the nation's tax system favors the wealthy. the white house staff working in-person or no longer being tested for covid every day as vaccination rates go up around the white house complex. a spokesperson for the white house maintains strong covid protocols like mask wearing, social distancing and regular test something happening. the change only affects those in contact with senior leaders like the president and the vp. more than 20% of recent blood donations from unvaccinated americans had covid-19 antibodies, that was during the first week of march a notable increase from 12% of people whose donations were tested in the first week of january. the presence of those antibodies means those donors were likely infected or exposed at some point. undue influence not grounded in science, those are some of the key damning take a ways from a recent review of some of the cdc's coronavirus guidance under the trump administration. now, this review requested by the cdc's new leadership found some guidance used less direct language than available evidence supported and that it needed, quote, to be updated to reflect the latest scientific evidence. the cdc also identified three documents that were not primarily authored by that agency but were presented as cdc documents. two of those three related to reopening the country and have been removed from the agency's website. all right. still

struggles to relieve the overcrowding at facilities along the border. carolina panthers's rosa flores is in the border in donna, texas. >> reporter: christine and laura, as tens of thousands of migrants make the dangerous journey here to the u.s. southern border, that is just the beginning. we have talked to migrants who describe overcrowded processing centers without showering facilities and some say that they slept overnight under a bridge waiting to get transported to a processing facility. once there, however, they do say that they get three meals a day. this as cnn learns that about 4,200 unaccompanied minors are in the custody of border patrol. dhs sending cnn a statement saying that border patrol officials, quote, do everything they can to take care of unaccompanied children in their care. according to peter shay, a lawyer who represents thousands of children that are in federal custody and he said that the capacity at the donna processing center that you see behind me is about 1,000 and that right now it's housing about 2,000. the head of homeland security directed fema to help create more shelters for unaccompanied minors. this is an effort to create space to move children out of the custody of border patrol and into the care of hhs. christine, laura? >> rosa flores for us in texas. to pennsylvania where police say a pennsylvania woman created
