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

WEST PALM BEACH, Fla. (AP) — Unemployment benefits for millions of Americans are set to lapse at midnight unless President Donald Trump signs an end-of-year COVID relief and spending bill that had been considered a done deal before his objections. He is demanding larger COVID relief checks for Americans and complaining about "pork" spending. But Congress has already passed the package by large margins in both houses. Failing to sign it will mean pain for those struggling to make ends meet and a potential federal government shutdown in the middle of a global pandemic. 581

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

With hospitals overwhelmed in much of the United States, the number of coronavirus cases jumped to record levels on Wednesday. The total of confirmed COVID-19 cases reported on Wednesday was 144,000, according to Johns Hopkins University.There were also at least 1,900 coronavirus-related deaths reported in the US in the last 24 hours, according to Johns Hopkins, marking the deadliest day of the pandemic since May 6, when 2,300 Americans died of the virus.Wednesday's case increase was the highest single-day total since the pandemic began and broke a record that stood for one day. The previous record of 140,000 new cases was set on Tuesday. Wednesday marked the ninth consecutive day in which there were at least 100,000 new cases reported.The news comes as governors and public health experts throughout the country have pleaded with citizens to wear masks and follow social distancing recommendations. A number of states were looking to re-impose restrictions in hopes of keeping hospitals from filling up with COVID-19 patients.Ohio Gov. Mike DeWine threatened to close restaurants, bars and gyms in his state again if things don’t change. The state had more than 6,000 coronavirus cases on Tuesday, marking a one-day record.“I am very well aware of the burden this will place on employees and the owners, but these are places where it is difficult or impossible to maintain mask-wearing, which we know now is the chief way of slowing this virus,” he said.In neighboring Indiana, the state is limiting the size of social gatherings, depending on the county.“Unfortunately, too many of us have let our guards down,” Gov. Eric Holcomb said Wednesday.Across the country in Nevada, the state’s governor issued a similar warning."We don't have much time to act to avoid a dangerous hospital surge and keep our economy going and keep people at work," said Gov. Steve Sisolak.The COVID Tracking Project, a project led by The Atlantic, shows that current coronavirus-related hospitalizations hurdled the 60,000 mark in the US on Tuesday for the first time since the start of the pandemic. The number of people hospitalized with COVID-19 has more than doubled in the last six weeks throughout the US.While state governors have been doing what they can to fight the virus, the White House has been silent on the virus since Election Day.The US is not alone in seeing a surge in cases. There has also been a significant surge of cases in much of Europe after going most of the summer and fall with a minimal number of cases. 2531
