With news of two highly effective COVID-19 vaccines on the horizon, health officials and scientists are giving us new insight into how we could gain herd immunity."If we think of the population as a single group of people with all similar risks and susceptibilities and behaviors, we need 60% of people to be immune, meaning that not only they don’t get sick, but also they don't pass on the virus to other people," says Dr. Stuart Ray, an infectious disease professor and herd immunity expert at Johns Hopkins University.Dr. Ray says achieving herd immunity with the help of a COVID-19 vaccine would mean enough people would either get the vaccine or already have recovered from the virus and be immune to help stop the spread of the virus."It's a little bit like this notion that if you’re going to pass on a message from a lot of people in a group, they have to speak the same language. And the more people don't speak the language, the harder it's going to be to pass that message and there’s a threshold at which the message just gets stopped," says Dr. Ray.Still, it would take a certain number of people to get the vaccine and have that immunity last in order to reach herd immunity. Stanford University's Dr. Bali Pulendran hopes that we can achieve herd immunity, even though there are a certain number of people who are still hesitant to take the vaccine."I think we should remember that a vaccine that is 95% effective is only effective if the majority of people in a population take it. If only half the population or only 60% of the population take it, then we are unlikely to have achieved the level of herd immunity that you need for curbing the disease," says Dr. Pulendran.And if the new COVID-19 vaccine requires two doses, how crucial will it be to make sure people receive that second round of immunization?Asked whether follow up will be a concern, Dr. Ray says, "I think it is a possible concern. We’re going to do a lot of learning. So, one of the things we’ve learned is that some vaccines we thought you needed multiple doses, one dose works pretty well."Doctors say research will be ongoing on the vaccine and the virus itself to ensure people will be protected as much as possible, because so many are hopeful for an end to COVID-19. 2268

When Sen. Bernie Sanders did this in 2013, he did it alone.On Wednesday, nearly four years later, Sanders introduced a new "Medicare for all" health care bill with a third of the Senate Democratic caucus by his side.Flanked at first by New York Sen. Kirsten Gillibrand and Connecticut Sen. Richard Blumenthal, Sanders called the costs of the current system "insane and unaffordable," promising that the average family would benefit financially under his plan "because you will no longer be writing checks to private insurance companies."For those whose taxes would go up, he added, "that expense will be more than offset by the money are you are saving with the elimination of private insurance costs." 710

When it comes to scaring us, Hollywood sure likes to have fun with spiders. But it's no fun when you have a real fear of them. So it's no surprise when it came time to see one in person, Cassandra Kidd was a bit nervous.  "Oh God I'm scared!" Kidd exclaimed.   She mustered up her strength to hold Rosie the tarantula. And after just a few seconds the fear was gone.  "It felt kind of like a ladybug but more gentle," Kidd says.    Kathleen Lewis peered over the wall as her grandson held Rosie.  "No I'm not as brave as my four-year-old grandson," Lewis says.  Fear kept her from holding the spider herself.  "Too many legs moving," Lewis says.When it comes to overcoming fears like Arachnophobia experts say educating yourself in an environment where you feel safe can make all the difference. The Spider Pavilion at Butterfly Pavilion is an example. Arachnids of all sizes hang out above.  A belief that spiders want to jump down on you is one of many misconceptions Mary Ann Colley, Vice President of Science and Conservation at Butterfly Pavilion, has heard about spiders.  "People are always saying, 'Oh, I am going to eat spiders in my sleep,'" Colley says. "That's not true."Another? The idea they want to bite you."Spiders really don't want to have anything to do with us," Colley says. "They want to do their own thing, they want to hunt for their food, create their webs."  Colley says only a small amount of spiders have a level of toxicity to actually hurt us. Butterfly Pavilion hopes sharing facts can help overcome fear."We want to be respectful of nature around us," Colley says. "So we always suggest to observe so just to take a look you can get close but you don't have to touch."  Seeing spiders in a new light. And facing your fear head on. 1850

While giving a daily briefing at a hospital near Miami, Florida Gov. Ron DeSantis was interrupted by a protester who called for DeSantis' resignation.Video from the press conference shows the protester yelling over DeSantis, accusing him of "falsifying information" and having "no plan" to combat the pandemic."Shame on you!" the protester said.He was later led out of the room by security. As guards grabbed him, the protester asked them to "social distance" and not touch him. The guards led him out of the media event anyway.DeSantis did not respond to the comments. 577

While politicians debate unemployment benefits, those who rent housing are hoping a deal is worked out soon. Experts say, so far, the COVID-19 pandemic hasn't impacted the housing industry, but that could soon change.Property managers are concerned the housing industry could see a repeat of the Great Recession from 2008.Michael Cohen is the owner of Asset Realty Management in Tennessee, which manages close to 900 properties. He says when the pandemic first hit in March, they started to see a major decline in vacancies and payments coming in. But when unemployment benefits started to kick in, things returned to normal.Cohen is worried now that enhanced unemployment benefits for millions of Americans have ended."Some people are still trying to dig their way out of that hole where they couldn’t pay for March and now we’re three months later and they’ve made major attempts to get caught up and here we go again. Definitely, I'm concerned about it," says Cohen.Jack Strauss is the Miller Chair of Applied Economics at the University of Denver. He says to prevent another housing crisis, eviction moratoriums need to continue along with additional unemployment benefits.“We care about evictions, not just for the family which is a personal tragedy in moving, but it could destroy the neighborhoods,” Strauss said. “You can be evicted from your house, these rental properties will remain unrented for long periods of time."Strauss says there are only about 5 million job openings across the country right now and 18 million people are unemployed."We already have a health problem. We don't want another severe economic problem in terms of evictions, in terms of unemployment people going hungry and homeless," says Strauss."I just keep waiting for this tsunami of lack of rent payments and people not being able to vacate and not being able to fill our vacancies and them staying vacant. Then once we get into the holidays, then things slow down even more," says Cohen.Strauss believes Congress will eventually come to an agreement and reissue some form of enhanced unemployment benefits to people. He hopes this next coronavirus stimulus bill really focuses on those who are suffering, including people of color, who Strauss says rent properties significantly more and are more than twice as likely to face evictions."This will even further hurt the Black family unit and Lanoti family unit, as well, if we don't have a moratorium. We need to help people of color because they're more likely to be hurt by a lapse in federal aid," says Strauss. 2559
