To end the pandemic, there need to be enough people immune to COVID-19 and there are two ways to do that: immunity through infection or from a vaccine."I think racing to herd immunity is the dangerous thing that I’m concerned about," said Dr. Stuart Ray, a professor of medicine at Johns Hopkins University School of Medicine.Herd immunity is when the spread of the infection cannot be sustained because the number of people who are immune is high enough. Some countries are considering it as a strategy to combat COVID-19.But Ray said it could not work in the US unless much more effective treatments are developed.He says on average, a newly infected person infects two others, so to have herd immunity from COVID-19 about 60 percent of people would have to become immune."We would have something like another 100 million people, maybe more, infected. 150 million more and even if the major complication rate is a fraction of 1 percent, we will still have huge numbers of deaths," said Ray.He said we also don’t know if just having had the infection once will create lasting immunity to control the spread."It possible that you could be immune enough not to get sick and still not immune enough to prevent that spread and so herd immunity is a tough bar for us to aim for because not only do we need 60 percent of people to be immune but we need them to be immune in a way that prevents them from infecting other people," said Ray.The other way to achieve herd immunity would be through a vaccine."Vaccines can work better, provide better immunity than the natural infection does. The new shingles vaccine provides great immunity and protects more than 95 percent of people from getting shingles," said Ray.Several vaccines are still going through the last phase of clinical trials to see if any also creates enough immunity to prevent passing the virus along.This story was first reported by Abby Isaacs at WMAR in Baltimore, Maryland. 1946

Think about this: working 80 percent of the hours for 100 percent of the pay.It's a concept a Denver company wondered if it’d work for them. This summer, Uncharted decided to put it to the test.CEO Banks Benitez says he started looking into it in 2019. He brought it to his executive board, and they decided it was something they were going to implement in 2020. Then, COVID-19 happened."So, we asked this question, 'Do we need to be working like crazy hours right now or do we need to really think about how we care for the mental health of our team and give people some space?'" said Benitez.This summer, they launched an experiment, hiring a third-party company to evaluate the efficacy of the experiment. The team worked Monday through Thursday, taking every Friday off. The hours were not made up throughout the week. The team worked four 8-hour workdays.They looked at three main things: performance, culture, and mental health."Performance stayed the same and was constant over the course of the experiment compared to previous performance," said Benitez.Culture, he says, slightly improved at the Denver-based company. People felt just as or a little more connected to members on their team.Lastly, to no surprise, mental health improved."I know that our best work comes when our team is healthy when our team is mentally healthy, when our team is aligned and in touch with each other," said Benitez.Benitez says there’s a different mentality that his employees bring in when they have a four-day workweek. They’re more focused and clearer about priorities. However, there are some downfalls"There’s a little bit less buffer time to kind of just go with the wind. You have to be really thoughtful about how you structure your time. And of course, the benefit of that is, Fridays are off," said Benitez.That helps lead to more downtime and time to refresh before starting the work grind again Monday morning."How do we situate Uncharted within the broader life that they’re living, [whether] that’s family, kids, adventures, travel, all that stuff. And if we can do that, I think the team will come back and perform better," said Benitez. 2153

TIJUANA, Mexico (KGTV) — Health conditions continue deteriorating Friday in Tijuana where thousands of migrants are camping, contributing to the opening of a second shelter 45 minutes away.The new shelter in an area known as El Barretal has a roof, dry floor and can house 3,000 migrants, Rodolfo Olimpo, a representative from Baja California State's Special Committee on Migration Issues said. Friday, about a thousand were shuttled by bus to the new shelter. There are no lighting fixtures, but migrants are using portable lights as well as flashlights.In the first shelter, the floor is mud, puddles everywhere and the entire area is littered with junk. One man brushed his teeth over a muddy puddle.10News Reporter Laura Acevedo went to Tijuana Thursday and spoke with the migrants living in squalor. One woman from Honduras, Leida Reyes, told her she thinks this is better than what they lived with back home.She said she couldn't walk around freely without fear, her children never attended school because it was too dangerous.When asked about the President's hard stance on migrants, she said she thinks he'll have a change of heart when he understands they're coming from a country that they can no longer live in safely.Reyes has been in TJ for about 20 days and is waiting for her number to be called so her case for asylum can be processed.No one has stated how long either shelter will be in place. 1418

They have traveled for days on foot and by bus. They are tired, hungry and desperate for a better life.President Donald Trump described the Central American migrants traveling in a caravan through Mexico as dangerous but many of them are women and children.As many of them stay south of the border to find work there and some 200 or so migrants continue their journey into the US, here's a look at some of their stories: 428

Title insurance: It’s another one of those mysterious fees buried inside the pile of paperwork you’ll receive at your loan closing. Who knows what it’s all about? All you’ve figured out is that lenders require a policy for their protection, and either you or the seller will have to pay for it — and then you’ll be asked if you want an owner’s title policy, too.Here’s how title insurance works, how to decide whether you need your own policy, and how much you can expect to pay. 492
