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

There are currently only a few treatments in helping to fight COVID-19, and one is antibodies from a Coronavirus survivor. But gay men wanting to donate are being faced with hurdles.A donation ban started with a 1980s restriction in the height of the AIDS and HIV crisis when the federal government created a lifetime ban on blood donations from gay men.The rule was replaced in 2015 with a regulation that requires a year of abstinence to donate blood.In April of this year, the FDA revised the abstinence period for gay men to donate blood or plasma from 12 months to three months in the wake of the Coronavirus pandemic.Chris Sanders with the Tennessee Equality Project says this is a start but these guidelines are not created equal."My call to action would be that the Congress of the United States will hold hearings on this rule and put pressure on the FDA to make this change," said Sanders.As the American Red Cross is pushing for more COVID-19 survivors to donate their antibodies to help sick patients, Sanders says some who are willing to help are being turned away."I talked to a gay man in East Nashville today who has survived COVID-19, and I asked him if the ban weren’t in place would you consider plasma donation and he said he would," said Sanders, "There are potential donors in Tennessee who would get turned away because of this unscientific, outdated FDA rule."Gay rights advocates say if this country wants to save more lives it will review what they call outdated policies.This story was originally reported by Kelsey Gibbs at WTVF. 1565

To a generation of children, Fred Rogers was a lot more than a soothing voice and a cardigan.On "Mister Rogers' Neighborhood," which had its first national broadcast on February 19, 1968, he sprinkled educational segments with soft-spoken wisdom.The show went off the air in 2001, and Rogers died in 2003. But he's making a posthumous comeback. The US Postal Service will commemorate him on a stamp next month, a documentary film about his beloved PBS show will be released in June and Tom Hanks will play him in a biopic.Fifty years later, Rogers' legacy still resonates.Here's a look at some of his more memorable lessons and quotes, from his show and writings.1.

Tide laundry detergent will soon be shipped in a shoe box, part of its parent company Procter & Gamble's push to adapt to online deliveries.P&G rolled out the new "Tide Eco-Box" on Friday. It features a twist-to-open pour for the detergent, a pull-out stand, and a measuring cup. The liquid formula, which contains less water than normal Tide, comes in a sealed bag.The version uses 60 percent less plastic than shipping an equivalent 150-ounce bottle of Tide since it doesn't require additional layers of cardboard boxing or bubble wrap. It's lighter and takes up less space in a delivery truck—saving P&G money on shipping costs."Its size is perfect for the e-commerce supply chain," said David Luttenberger, global packaging director at market research firm Mintel. "It's an easy package for nearly any consumer to pick it up, manipulate the opening features, and dispense from."Tide Eco-Box will join Tide's lineup on Amazon (AMZN), Walmart's website (WMT) and other P&G (PG) retail partners' sites starting in January. 1047
