in a couple of moments -- here he is. we will be seeing the president visit this small business in chester, pennsylvania. this is all part of his administration's help is here tour, promoting the $1.9 trillion relief package he signed just last week. president biden, though, is facing renewed pressure to do even more. senate majority leader chuck schumer is continuing to press him on forgiving $50,000 in student loan debt, but president biden made it very clear at a cnn town hall last month that he does not support canceling such a large amount. first thing's first, to vaccination news. getting americans vaccinated, getting them spending those stimulus checks and hopefully invigorating the u.s. economy. we start with our cnn chief white house correspondent, kaitlan collins. they is there, in chester, pennsylvania. can you speak about the president's intentions with his visit there today. >> i think what you're going to see president biden do today is want just make the case for this coronavirus relief bill. what this entire week is designed to do, on this stop and several others with officials. the basic argument from white house official is this plan was designed to help people in places like chester, pennsylvania, where a lot of people are living below the poverty line, where the pandemic has hit people really hard. you're seeing a lot of low income people that need that boost. we just saw president biden sign into law with that major cash infusion you got last week. he'll visit this small business around the corner from where i'm standing right now. they'll also be talking about how this plan is going to help small businesses either stay afloat or rebuild their trajectory as we are trying to make the economic recovery, given what we've seen happen over the last year to so many small businesses. not just here in pennsylvania but throughout the country. of course the challenge that is going to be facing the biden administration and they seem well aware of is implementing this bill, given it is so large. that's what they've been touting. t i think they're aware of that. that's the other thing you're seeing biden talk on the road, not just today but other days this week. they're looking at the long-term strategy here. this is something president biden, there are several aspects of this he wants to make long term. what's temporary in this bill, including that child tax credit, that's something he actually wants to see put in place. that's something they're going to make that argument for down the road. i think that's also part of what's factoring into this stop and others you'll see president biden make this week. >> great. we'll look for him momentarily. for now, kaitlan, thank you in chester. concerns are rising in europe about the safety of the astrazeneca vaccine. that's causing more eu countries to pause that rollout. its makers are reportedly weeks away from applying for emergency use authorization here in the u.s. nearly 12% of americans have been fully immunized and millions more are being vaccinated each and every day. officials want to maintain that mom momentum, especially with spring break parties and reopened economies, potentially fueling a new surge. cnn's alexander field has more. >> reporter: spring braeshgz rushing beaches across the country. >> i already had covid once, so i'm not worried about it. >> reporter: a year of hardship fueling the desire to take a break. >> the problem is not just miami. the problem is we have too many people coming. we have too many people coming that just want to let loose in ways that are unacceptable. >> this is still not a time to travel just because. think twice before traveling, if you don't have to. >> reporter: despite the warning the tsa is reporting the biggest five-day travel period since the pandemic, more than 6.4 million fliers. perhaps they're heading to the growing number of states rolling back restrictions. in california, los angeles county is opening restaurants for indoor dining at 25% capacity. >> it's spring break so we're going to l.a. to have fun. and disneyland opens on thursday. >> reporter: wyoming is among the latest states to lift its mask mandate. the country is still averaging more than 55,000 new cases a day. the rate of decline in new cases is getting smaller. >> we know from over the summer federal researchers have shown whenever states relax their universal mask mandates, you do see a rise in infection. l likewise, we don't need to see more destruction than we've already seen. >> reporter: 7.8 of the u.s. population is fully vaccinated. some states are surging ahead to make all adults eligible for vaccines. still health experts say we must fight to keep new variants in check. >> we can really still try to wear masks and do all of the things we should have been doing to prevent all of this transmission in the beginning. we can prevent that variant from taking hold in the united states, then we'll be in a much better place to get herd immunity. >> reporter: a new study shows asymptomatic or undiagnosed covid-19 infections in the u.s. may have been twice the official case count as of september 30th last year. the red cross is finding 1 in 5 unvaccinated blood donors has antibodies. as for a better school year, moderna is moving forward with clinical trials on young children, even babies as young as 6 months old. brooke, a lot of parents are hearing that news and wondering how quick their child can get vaccinated. dr. fauci has said possibly fall for older children and most likely not until early 2022 for young children. a lot of data to collect there. >> it's a huge point. perhaps that is the beginning of true normalcy with our kids. being vaccinated and being able to be back in school. thank you. i want to start on precisely that point with my next guest. dr. gounder, cnn medical analyst, infectious disease specialist and epidemiologist. she was also a member of the biden/harris transition covid group. let's jump in on this point. we've learned the first kids have been vaccinated in moderna pediatric vaccine trial. it's kids between the ages of 6 months and 11 years of age, they're being tested. how important is this? >> we're not going to be able to vaccinate children until the vaccine has been studied in that population. this is going to be important to getting to that holy grail of herd immunity. we need to be able to, one, have the data on the safety and efficacy of the vaccine in kids and then vaccinate all of them. this is an important start and an important milestone in all of this. >> i don't hear you jumping all over it, which tells me we all need to slow our roll in thinking there's going to be a bunch of kids vaccinated. i hear you loud and clear in what you say and what you don't. my other question, we're learning about this new jama study that a number of adults who have gotten covid in the u.s. could actually be twice the official case count. to add to that, the american red cross said there is antibodies in 1 in 5 blood donations from unvaccinated people. i heard that today. basically, they're saying that device the number of people had covid than we ever thought. what do you take away from that? >> another way of looking at this is let's say 20% of the american population has been infected and yet we ended up with over 500,000, over half a million deaths as a result. so, it's really fortunate we had the mitigation measures in place because if a larger proportion of the population was exposed, was infected, our death toll would have been that many fold higher. i think the other important message to get across here is we're very far from herd immunity with only 20% of people exposed and infected. even those people may not be immune because natural infection provides much less reliable, often less robust, less long lasting immunity. we really do need to get a lot more people vaccinated before we get to herd immunity. >> that was my next question, if more people had covid than we realized, if this gets us to herd immunity faster and i'm hearing not necessarily. as more people get vaccine, there are more anecdotes from folks, wiped out for a day, flu-like symptoms, sometimes after the first dose, sometimes after the second dose. can you remind people as more and more people are eligible to get the vaccine, why these side effects occur and why people still need to get this vaccine? >> we're seeing about 10%, 15% of people getting vaccinated have these side effects, the flu-like symptoms, maybe a bit of a fever, headache, muscle pains, especially after the second dose. what that really means is your immune system is seeing the vaccine, it's developing an immune response so that means the vaccine is working. i can tell you, as somebody who has been vaccinated as well, those side effects are nowhere near how bad covid can be. and really, you do want to be vaccinated, you want to be protected against those severe cases, the hospitalization, the death and just a little comfort for a day after, especially your second dose, is not a high price to pay for that protection. >> okay. >> i hear you loud and clear. thank you so much. >> my pleasure. we do have breaking news this afternoon. a new u.s. intelligence report on the 2020 election is indicating that russia tried to interfere to help then president donald trump and, quote, denigrate candidate biden. details ahead. plus, the white house is under growing pressure when it comes to the humanitarian crisis at the southern border. more kids are showing up each and every day. but president biden says he has no plans to visit the southern border any time soon. also, north korea is breaking its silence on the new administration, issuing this new warning as the u.s. learns north korea could be ready to carry out a new weapons test. we have those details for you. you're watching
