The first experimental COVID-19 vaccine in the U.S. is on track to begin a huge study next month to prove if it really can fend off the coronavirus, while hard-hit Brazil is testing a different shot from China.Where to do crucial, late-stage testing and how many volunteers are needed to roll up their sleeves are big worries for health officials as the virus spread starts tapering off in parts of the world.Moderna Inc. said Thursday the vaccine it is developing with the National Institutes of Health will be tested in 30,000 people in the U.S. Some will get the real shot and some a dummy shot, as scientists carefully compare which group winds up with the most infections.With far fewer COVID-19 cases in China, Sinovac Biotech turned to Brazil, the epicenter of Latin America’s outbreak, for at least part of its final testing. The government of S?o Paulo announced Thursday that Sinovac will ship enough of its experimental vaccine to test in 9,000 Brazilians starting next month.If it works, “with this vaccine we will be able to immunize millions of Brazilians,” said S?o Paulo′s Gov. Joao Doria.Worldwide, about a dozen COVID-19 potential vaccines are in early stages of testing. The NIH expects to help several additional shots move into those final, large-scale studies this summer, including one made by Oxford University that’s also being tested in a few thousand volunteers in Brazil.There’s no guarantee any of the experimental shots will pan out.But if all goes well, “there will be potential to get answers” on which vaccines work by the end of the year, Dr. John Mascola, who directs NIH’s vaccine research center, told a meeting of the National Academy of Medicine on Wednesday.Vaccines train the body to recognize a virus and fight back, and specialists say it’s vital to test shots made in different ways — to increase the odds that at least one kind will work.Sinovac’s vaccine is made by growing the coronavirus in a lab and then killing it. So-called “whole inactivated” vaccines are tried-and-true, used for decades to make shots against polio, flu and other diseases — giving the body a sneak peek at the germ itself — but growing the virus is difficult and requires lab precautions.The vaccine made by the NIH and Moderna contains no actual virus. Those shots contain the genetic code for the aptly named “spike” protein that coats the surface of the coronavirus. The body’s cells use that code to make some harmless spike protein that the immune system reacts to, ready if it later encounters the real thing. The so-called mRNA vaccine is easier to make, but it’s a new and unproven technology.Neither company has yet published results of how their shots fared in smaller, earlier-stage studies, designed to check for serious side effects and how well people’s immune systems respond to different doses.Even before proof that any potential vaccine will work, companies and governments are beginning to stockpile millions of doses so they can be ready to start vaccinating as soon as answers arrive.In the U.S., a program called “Operation Warp Speed” aims to have 300 million doses on hand by January. Under Brazil’s agreement with Sinovac, the Instituto Butantan will learn to produce the Chinese shot.___AP journalist Marcelo Silva de Sousa contributed to this report.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The funeral for Rayshard Brooks — an Atlanta man who was killed during an altercation with police earlier this month — took place Tuesday in a church with connections to the Civil Rights movement.Brooks' funeral was held at Ebenezer Baptist Church in Atlanta — the same church where Rev. Martin Luther King Jr. served as a co-pastor between 1960 and 1968.Dr. Bernice King, one of Martin Luther King's daughters, spoke during Brooks' funeral.Actor, writer and producer Tyler Perry provided the funds for Brooks' funeral. The funeral comes after an hours-long public viewing on Monday afternoon.Brooks was shot and killed in a Wendy's parking lot by former Atlanta Police Officer Garrett Rolfe on June 12. Rolfe's partner, Officer Devin Brosnan, first encountered Brooks after Brooks had fallen asleep in his car while waiting in the restaurant's drive-thru line.Rolfe arrived on the scene a few moments later. The officers subjected Brooks to a field sobriety test, which he failed. He later offered to lock his car and walk home, but Brosnan and Rolfe told Brooks they would be taking him into custody.As the officers attempted to handcuff Brooks, a struggle ensued. Brooks was able to grab Brosnan's stun gun and attempted to flee the scene. As he fled, Brooks appeared to point the stun gun in the direction of the police. That's when Rolfe shot Brooks in the back. Brooks later died in surgery at a local hospital.Fulton County District Attorney Paul Howard says Rolfe kicked Brooks after shooting him but before calling for emergency medical help. He also alleged that Brosnan stood on Brooks' shoulder. Both face charges in connection with Brooks' death, with Rolfe facing murder charges. 1701

The coronavirus pandemic is now starting to cause sporting events in 2021 to become canceled.On Thursday, the NHL announced that it has canceled the 2021 Winter Classic and NHL All-Star Game.The Winter Classic has become the NHL’s signature outdoor event for the last decade, generally played outdoors on New Year’s Day. The game was originally slated to be played between Minnesota and St. Louis in Target Field.The NHL All-Star Game, originally scheduled for Jan. 31, 2020, has been canceled. The NHL planned on playing the game in Sunrise, Florida, home of the Florida Panthers.The NHL said it intends on playing a Winter Classic in Minnesota and an NHL All-Star Game in Florida in the near future.“Fan participation, both in arenas and stadiums as well as in the ancillary venues and events that we stage around the Winter Classic and All-Star Weekend, is integral to the success of our signature events,” said NHL Senior Executive Vice President & Chief Content Officer Steve Mayer. “Because of the uncertainty as to when we will be able to welcome our fans back to our games, we felt that the prudent decision at this time was to postpone these celebrations until 2022 when our fans should be able to enjoy and celebrate these tentpole events in-person, as they were always intended. We are also considering several new and creative events that will allow our fans to engage with our games and teams during this upcoming season.”Due to the 2019-20 season not concluding until last month, the NHL said it does not intend on starting the next season until Jan. 1, nearly three months after its typical season opener. 1632

The FDA is offering formal guidance on the amount of inorganic arsenic allowed in infant rice cereal.Exposure to inorganic arsenic has been associated with neurodevelopmental effects, according to the Food and Drug Administration, including lung and bladder cancer risk. Arsenic occurs naturally in the soil, and rice has been shown to absorb a small amount during the growing process.The new guidance identifies a level of at or below 100 micrograms per kilogram and is based on draft guidance from 2016. The guidance is recommended, but not legally enforceable.“It is important to note that the agency’s data show that most products on the market are already below this level and that parents and caregivers should know that a well-balanced diet also includes a variety of grains like oats and barley,” said a statement from Susan Mayne, Ph.D., director of the FDA’s Center for Food Safety and Applied Nutrition.According to the FDA, results from testing in 2018 showed 76 percent of samples were at or below the 100 ppb level, compared to 47 percent of samples tested in 2014 and 36 percent of samples tested between 2011-2013.The FDA attributes the drop in inorganic arsenic presence to changes manufacturers are making in sourcing rice and testing their ingredients. 1279
