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

TOPEKA, Kan. (AP) — A FedEx executive says a higher-than-normal volume of Christmas-season package deliveries won’t interfere with the company’s effort to ship coronavirus vaccine doses.Jenny Robertson, a FedEx senior vice president, said two trucks on Sunday moved doses of a vaccine developed by Moderna and the National Institutes of Health from a factory in Olive Branch, Mississippi, to the company’s world hub in nearby Memphis, Tennessee, so that shipments could be loaded onto its airplanes bound for multiple states.She said the company is keeping its networks for shipping the vaccine and handling Christmas packages separate.“Nothing’s more important than the delivery of the vaccine to us, but we have put in place distinct networks that are keeping e-commerce moving through our ground network and vaccines moving through our express network,” she said. “We’re able to manage this volume right now.”Robertson said the company has seen holiday-level volumes for shipping packages since March because consumers switched how they buy products during the pandemic. 1081

TIJUANA, Mexico (KGTv) - A group of about 500 self proclaimed migrants from the caravan demanded more public restrooms and the Benito Juárez Stadium be reopened for them to sleep in Thursday.Before the planned press conference, a Honduran yelled at a French activist, calling him an infiltrator. The man defended himself, saying he was there trying to protect the community.Later during the press conference two men yelled at the group telling them to leave. Later Thursday, a humanitarian offered a warehouse for the migrants to sleep in.This all two days after a different group of 100 migrants demanded entry into the U.S. or ,000 each to return to their home country.Related link : Migrants demand entry or ,000 during march to US Consulate in TijuanaIn the U.S. some American sympathy is drying up after hearing these demands, "what a joke, what gives them the right to blackmail our country, our president, to give them ,000? Are you kidding me? Who does that? Criminals?" Agnes Gibboney walked their path. She was born in Hungary and her family tried twice to escape.The first time, when she was two, she woke up and started crying, causing them to get caught. She said everything was taken from them. Gibboney said the second time they escaped, an aunt drugged her so she would sleep through the escape.They lived in Brazil for more than a decade and came to the U.S. via her father's Green Card. "My heart goes out to them, but this is not how you do it, because if you do have a legitimate refugee issue, you go to the port of entry, you go to the embassy in your state in your country," she said.Her feelings on border security solidified in 2002, when her son was shot and killed by a man she calls a coward, gangster and undocumented. "He was going to shoot my son's friend in the back, because they got into fights and he wanted to get even," she said the bullet was not meant for her son, a father of two.The pain she says, has never gone away, "my world.... my world just collapsed."She believes all immigrants must be vetted to protect our nation. She will be speaking Friday at a press conference held by families that have been traumatized like her, at 11:30 a.m. at the San Ysidro Port of Entry. 2232

Things at grocery stores seem relatively calm now, in comparison to how it was back in March. Remember the toilet paper fiasco?But as we hear talk about another wave of coronavirus infections, some are wondering if grocery supplies will take another hit.We went to experts who track grocery data. They say what we saw earlier this year was historic.“Those mid-March weeks were the largest we've seen in the history of grocery shopping. I don't expect to ever see big waves like that again,” said Anne-Marie Roerink, President of 210 Analytics.People first stocked up on just cleaning items and then they started stocking up on all types of items, including pantry foods and that precious commodity – toilet paper.Roerink says that while it is possible people will stockpile again later this year, toilet paper may not be on the list. Cleaning items may become hard to find again. The timing of all this really depends on the virus and how cases evolve.“Should it come down to where the virus is big enough of a wave or we might go back down to a shelter in place, or where people feel more safe at home than they do out and about, I can see where our grocery spending will go back up,” said Roerink.Earlier this year, holidays like Mother’s Day and Father’s Day actually contributed to the clearing of grocery shelves. They’re typically holidays where we go out to eat, but that wasn't really an option in most places. So, people had to improvise.“All of a sudden, retail had to absorb all those dollars to take care of mom and cook her a fun brunch or dinner, so we had an enormous peak again for Mother's Day and Father's Day,” said Roerink.That means holidays like Thanksgiving and Christmas could change how things work out at the grocery store as well.Generally, supply and demand has started to normalize, but grocery sales are still about 10% higher than what they normally are. Though, prices could still change depending on the demand. 1952
