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 Trey Ganem heard about the shootings in Sutherland Springs, he jumped in his car and drove 100 miles to the mourning town.The 46 year-old businessman didn't come just to bear condolences. He had something more tangible to offer: coffins.Ganem runs a casket design company in Edna, Texas, another small town east of Sutherland Springs.His seven employees build personalized coffins that usually sell for about ,500. He is offering to provide free custom-made coffins for the people slain Sunday at First Baptist Church. So far, he's gotten requests to make 15 caskets."When I first started five years ago, children burned in a fire in Edna, Texas. I donated caskets to the family. I knew the kids" he told CNN. "It was the most emotional time in my life."The tragic news out of Sutherland Springs stirred up the same emotions for Ganem."Immediately my heart opened up and I was like 'yes, we can do this,'" he said. "It's a small town. People that felt like they were safe ended up in this tragedy.""What we want to do is start the healing process here," Ganem said. "I want to make sure that we celebrate the lives of the people who were there."Ganem's caskets are always personalized. For some of the younger victims, he plans to paint coffins with princesses and Barbie. The smallest one will fit a 1-year-old girl.He sees his gesture as a way to help grieving families get through their darkest time."We want people to know that we are here for them. We are praying for these families that were affected and we will continue to." 1547

When the Trump administration first asked the Pentagon to send troops to the southern border, they wanted them to perform emergency law enforcement functions, CNN has learned.The Pentagon said no.According to two defense official familiar with the request, the Department of Homeland Security asked that the Pentagon provide a reserve force that could be called upon to provide "crowd and traffic control" and safeguard Customs and Border Protection personnel at the border to counter a group of Central American migrants walking to the U.S. border to request asylum.The Pentagon rejected the request on October 26, according to one of the officials, even as it signed off on providing DHS with air and logistics support, medical personnel and engineers.The request was turned down because the Department of Defense felt that active duty troops do not have the authority to conduct that type of mission unless they are granted additional authorities by the President.Defense officials have repeatedly emphasized the troops at the border are there to support civil authorities and that they are not expected to come into any contact with migrants. 1154
