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

This data hack is huge -- 1.4 billion passwords are now floating around on the dark web. In December, a massive data leak was discovered, and many computer gurus are capable of accessing the information, said cybersecurity expert Dan Petro. "Certainly like one of the biggest password leaks ever," said Petro.Hackers combined smaller lists with new hacked data into one massive database."If you're like almost everybody else, you probably just have one password or maybe a small set of passwords you use for basically everything. So having these leaked online is threatening not just to your one account but perhaps all the other ones," Petro said.Rob Hanna was one of the many internet users whose password was exposed. Within seconds of accessing the database, someone could easily find his hacked password and email."I’m really quite stunned about that. That's scary. And I've been pretty careful about trying to really manage that for a lot of years," said Hanna.Even if your bank account password is different, Petro said with access to your email account, hackers can get into your bank using the "forgot password" feature. It often emails you a link that lets you or a hacker set up a new password.Security experts recommend frequently changing passwords, using hard-to-guess passwords. For those who have a tough time remembering passwords, something called 2-factor authentication can help.Most email services let you turn it on in your settings. Whenever someone tries to sign into your account from a new computer or phone, not only do they need your password but a secret code texted from your email company to your phone. You must enter both."That way if your password gets leaked in a large online database such as this one attacker still won't be able to log in," said Petro.Hanna, who has kept a spreadsheet of his emails and passwords for different sites, now has a task ahead of him: figure out which of the several dozen logins he uses must be changed so no one does any damage using his hacked information."So if that kind of got out and someone really wanted to kind of take a run at me that could give them a lot control," Hanna said. 2199

The year 2020 has proven it knows how to challenge people who live in places like the Gulf Coast.Multiple storms slammed the state of Louisiana and the city of Lake Charles.Dr. Tyson Green lost his home in Hurricane Laura in August. His family evacuated before the storm as he rode it out in a Lake Charles hospital so he could be close to his patients.His community now faces a recovery that is expected to take years.“I don't know how you begin to put it into words, to be honest with you. We’ve had a tough year, to say the least," Green said. "I think with the combination of the pandemic, the hurricanes, the resurgence of the pandemic that beat us while we were down, it’s been rough, but we are getting better we are coming together as a community."Since the storm, he's raised money for nurses and healthcare workers who were impacted by Mother Nature this year. His GoFundMe has raised more than ,000 dollars. The money raised is key, especially during the holiday season."It was such a blessing to be able to give them something through the GoFundMe efforts that we did. The ability to give them a better Christmas, people that lost everything, even the people who lost what they had and were reimbursed by whatever means insurance or FEMA, they still didn't have the means. They still didn’t have the extra money that we need around the holidays for their kids," Green said.2020's hurricane season broke several records. Thirteen of the 30 named storms became hurricanes during 2020's hurricane season. 1524

This year’s first rehabilitated eagle is released back into the wild Monday, at Pioneer Trails Recreation Area, just north of Aurora, Colorado.She was originally found near this park March 2, with no apparent injury, but she wasn't flying.“We tested her and she had a lead level of 18.3,” said Betsy Finch, manager of Raptor Rehabilitation. “And that is micrograms per deciliter. Anything above 10 toxic.”Bald eagles are getting sick and dying from lead poisoning after eating the carcasses of animals shot with lead bullets. The Fontenelle Forest Raptor Recovery Center typically sees 20 eagles a year, it’s already hit that number this year; only two have survived.For the past seven weeks, Finch, has nursed the eagle released Monday back to health, treating her for lead poisoning, as she has done with many other eagles.“This is a real eagle celebration today,” Denise Lewis, Director of Raptor Recovery said. “This is what it’s all about.”Before her big moment, she is banded and photographed.It's bittersweet. Finch invests a lot of time nursing these birds back to health. But she insists, she isn't sad to see her go.“Not really,” Finch said. “They don't belong with us.”Out in the wild, she'll go right back to hunting, and soaring free.“If she has a mate out there she will find that mate,” Finch said.And she said it's not too late for her to breed yet this season.If you find an injured raptor, such as an eagle or an owl, call the Raptor Recovery Rescue Hotline at 1866-888-7261. 1531
