first, adults 60 and over should is not start taking aspirin to prevent cardiovascular disease. for that group, the risks are felt to outweigh the potential benefits. the second recommendation, if you're 40 to 59 and have an estimated ten-year risk of 10% or greater ten-year risk of having a heart attack or stroke, starting low-dose aspirin, i'd a81 milligrams a day may provide a small benefit. your health care provide kerr calculate that risk using an online calculator. >> that's interesting. who should keep taking their low dose aspirin? >> so important, people who have evidence of stroke or cardiovascular disease. for instance, somebody who has already had a heart attack or stroke should keep taking the aspirin. this is not for people who need to take aspirin for another condition or not for people who need to avoid aspirin because they have an increased risk of bleeding. finally, if you're already taking aspirin and you don't fit into those categories, that's lots of people out there, check

to 11. that's important because the cdc says 75% of that age group has had covid at least once. here in the nation's capital, we learn vice president kamala harris tested positive for covid-19. the white house says president biden is not considered a close contact. we have a lot of news to get to tonight, and we'll start with cbs' mola lenghi in new york city. good evening, mola. >> good evening, norah. the vice president tested positive this morning after starting her day at the west wing. we should note she is vaccinated and boosted. but that comes with the white house already having covid at the top of their agenda, with the roll-out of a new plan to make that powerful anti-covid drug widely available on pharmacy shelves nationwide. paxlovid is one of the most effective antiviral tools for treating covid, if only more people could get their hands on it. >> over the last few months, the administration has worked very hard with pfizer to increase the

supply of paxlovid and acquire more and more doses for the american people. >> reporter: until recently, it was hard to find. but with production up, the biden administration today announced it wants to make paxlovid available for free and is launching an effort to double the supply, getting the pills into 20,000 more pharmacies over the coming weeks. >> if there were ever a drug to ask your doctor for, paxlovid would be that drug. >> reporter: it reduces the risk of covid hospitalization and death by 89% in high risk adult patients and is already authorized for people 12 and over who are considered high risk, often with underlying conditions like obesity, hypertension, diabetes, and asthma. but it must be taken within five days of symptoms, often igniting a race to find a pharmacy that actually has it in stock. >> and as you can see, the cough is still working its way out. >> still there. >> reporter: it's a scramble gabe rice knows all too well. >> have you noticed its impact? >> yeah, after a couple of days, i definitely was feeling better.

testified before a senate investigative company, probing balfour beatty, one of the nation's largest housing contracting companies. a panel report found the contractor has engaged in ongoing mistreatment and mismanagement that has put the health and safety of military families at risk. senator jon ossoff chaired the review. >> we're talking about lead, asbestos, mold and mildew, ceilings falling in, requests for urgent maintenance never acted on. it's completely unacceptable. >> reporter: last year, the company pleaded guilty to fraud and was fined $65 million for falsifying work orders to obtain performance bonuses from the military. >> why should we believe mr. taylor that a company that has been engaged in major fraud against the united states is fixing this? >> things go wrong. we don't always get it right the first time. we're not perfect. >> their explanation i believe is very coached. >> reporter: at this point, what do you want? >> there is no resolution for my daughter. but i would like for her to have

unions has been dropping for decades, but suddenly -- >> what do we want? >> union contract! >> reporter: in the last year or so, the winds have changed. unionization efforts are under way at tech companies like apple and google, media organizations like "the new york times" and conde nast, and among grad student, delivery drivers, and baristas. since december, when a starbucks in buffalo was the first to vote to unionize, workers at 16 starbucks stores have followed suit. yes, they vote one store at a time. >> we've had a lot of intimidation and a lot of efforts to stop us, but we're here. >> reporter: and over 200 more have petitioned to vote. and then three weeks ago, there was the news that stunned the business world about america's second largest employer. >> it's amazon versus the people, and the people have spoken. >> reporter: jfk-8, a massive amazon warehouse on staten island that employees 8300 people voted to unionize.

>> we want to thank jeff bezos for going into space. because when we was up there -- >> people saying dude, these efforts never succeed. >> of course. i think everybody wrote us off. everybody didn't believe that we would even get to an election, let alone win. >> reporter: former amazon worker chris smalls led the union drive. but that wasn't his original plan. >> i had no intentions on unionizing. just trying to do the right things and protect people from dying from covid-19. >> reporter: in march 2020, he organized a walkout to protest the lack of face masks and other covid gear at jfk-8. amazon fired him, and in a leaked memo, an executive called him -- what's that quote? >> not smart or articulate. >> reporter: he soon learned he wasn't the only unhappy amazonian. >> they take care of the robots better than humans. >> reporter: another amazon warehouse on staten island begins a unionizing vote tomorrow. workers brett, matt and martha

>> reporter: but not this time. so i think what you're saying is you succeeded because you were smart and articulate? >> pretty much. >> reporter: amazon declined an interview, but told news a statement we don't think unions are the best answer for our employees. our focus remains on work directly with our team to continue making amazon a great place to work. amazon is also challenging the validity of the jfk-8 vote and points out that it already offers better than average pay and benefits. $15 an hour starting wage and health insurance. but ruth milkman says it's abou% more than dollars. >> workers want respect. they want to be treated with dignity. and i think you can see that really clearly in this story at staten island. they're treated like machines. >> in what ways are these workforces and these unions different from the old union factory efforts? >> what's different i think is the zeitgeist that especially young workers who lived through a lot of turmoil, they have

these high expectations for what their work life is about to be about, and then they can't afford the rent. they may have a lot of student debt, they end up living with their parents. this is not what they were promised. the pandemic also createsed a labor shortage which gave people more leverage and less fearful of organizing. unions are cool again for this generation. >> reporter: for many of the workers at jfk-8, chris smalls is definitely cool. one of them drove by during our interview and expressed his own thoughts on the unionization efforts. >> [ bleep ]. >> reporter: what did he say? >> i won't say that word. i guess he is pro union. >> that was david pogue reporting. if you have young children, you're probably well aware that the nation is in the grip of a child care crisis. costs have spiked in recent years, forcing many parents, mostly mothers, out of the workforce to care for their kids. and despite the rising costs, child care professionals remain among the lowest paid workers in the country. all this has forced thousands of

financial problems before covid. then when the virus hit and enrollment dropped, she had to begin letting teachers go. >> so i started with laying some off. and then my leadership team, i just couldn't afford the higher paid employees. >> reporter: as covid started to ease up, did parents want to send their kids back? >> the issue was not the number of kids that we could enroll. we have a waiting list of over 50 children. five of our classrooms are closed because we cannot find teachers. >> reporter: why can't you find teachers? >> it is the low wages that we pay. and then we have hobby lobby paying $18 an hour with some benefits. and we just can't match that. >> reporter: in contrast, companies like the craft and the hobby chain, slayton says she can only afford to pay her employees an average of $13 an hour without raising prices beyond what families he is serves can afford. so she is trapped in a vicious

cycle, and she is not alone. >> there is a crisis for american children, their families, and the child care workers. >> reporter: leah austin who runs the center for the study of child care employment at the university of california berkeley says many other co countries often all parents some subsidized child care for young children. things in the u.s. have gone from bad to worse. what did the pandemic do to the availability of child care? >> we have lost about 16,000 child care programs across the country. about 131,000 jobs. >> reporter: federal emergency covid relief funds did provide $39 billion to support child care, helping struggling centers and some parents like raquel franklin. she works as a caregiver at kitty campus, and as an essential worker, now gets vouchers to pay for her two children who are enrolled here.
