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

With home-court advantage taken out of the equation this year because of COVID-19, the NBA playoffs look nothing like they once did. And on Wednesday, the season took yet another dramatic turn with at least one team boycotting the championships.The Milwaukee Bucks boycotted their game to protest the shooting of Jacob Blake in Kenosha, Wisconsin. It raises the question: what does this mean for the current moment of racial reckoning the nation has found itself in?Dwight Lewis, an activist during the civil rights movement, says it's about more than one game or any sport in particular."Sometimes you have to do things to get attention and say, ‘I can’t take this anymore. I’m mad as hell and I’m not going to take it anymore,’" the now 72-year-old activist explained.For athletes and teams in the national spotlight, it's about using their platform to get the country to pay attention."If you don’t speak out now, what are people going to say about you? That’s what was great about what the Bucks did," he added.Professional athletes using their platforms to protest racial inequality is nothing new. The first time it happened was during the 1968 Olympics when two African American runners raised their fists during the national anthem to call attention to the civil rights campaign.Lewis says decades later professional athletes are still harnessing the power that comes with their position to help enact change and move the national dialogue on race forward."This is 2020. We’re no better. Racism is still as American as apple pie, unfortunately. So, what did we do to keep these people from not wanting to walk off the basketball court or the football field? What did we do?" 1690
