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 coronavirus pandemic has had a big impact on businesses of all kinds, restaurants and retailers alike are closing permanently and others are doing what they can to financially survive.That also means it could be a good time for consumers looking for specific items to save some money.The website rather-be-shopping.com compiled a list of 13 items that have become cheaper during the pandemic.Items like clothing for the whole family. Retailers like Macy’s, Stein Mart, Ann Taylor, and many more are closing anywhere from several stores to most of them. That could mean deep discounts during liquidation sales.Those looking for a home or want to refinance will find low mortgage rates right now. Mortgage rates have hit an all-time low.Gas is about 50 cents cheaper nationally than it was in the summer of 2019. Maybe it’s time for a road trip or long drive and save on fuel prices.That also contributes to low shipping costs. Many online sites are offering no or low shipping costs right now.In time for school to start, technology is cheaper and many places are offering discounts on laptops and electronic devices and headphones that can be used for at-home learning. There are also 16 states with "no sales tax" weekends to encourage shopping. 1259

The Food and Drug Administration has approved remdesivir as a treatment for the coronavirus.The move comes less than a week after the World Health Organization published results of a large study that suggested remdesivir did not help hospitalized COVID-19 patients.A previous study by the U.S. National Institutes of Health found the antiviral drug shortened recovery time by five days, on average. That led to the drug getting emergency use approval in the U.S, as well as many other countries.The FDA’s decision on Thursday formally approves remdesivir as a treatment option, and makes it the first fully-approved treatment in the U.S.None of the studies have found the drug can improve survival rates.Remdesivir is one of the treatments President Donald Trump received when he contracted COVID-19 earlier this month. It is usually given over five days and works by helping to stop the replication of COVID-19 in the body. 932

The brother of an unarmed black man killed by police interrupted a Sacramento City Council meeting on Tuesday as chants of the victim's name filled the chambers, illustrating how the fatal shooting has sparked emotions in this California city."Stephon Clark. Stephon Clark," Stevante Clark and others chanted in the first meeting since the fatal shooting on March 18."Louder. Louder," said Stevante Clark, who hopped on the dais and yelled an expletive at Mayor Darrell Steinberg.Standing in front of the council chambers with others, Stevante Clark said: "The mayor and the city of Sacramento has failed all of you," citing high rent, gang violence and poverty in the city.The outburst forced council members to take a brief recess. 746
