The fatal New York City helicopter crash that killed everyone on board except the pilot may have been caused by a passenger's piece of luggage, the pilot told investigators.The pilot said one of the passenger's bags may have inadvertently hit the emergency fuel shutoff button, leading to the crash that killed five passengers, a senior law enforcement official said.The National Transportation Safety Board will try to determine the cause of the Sunday evening crash, the Federal Aviation Administration said. The NTSB tweeted that an investigation team of 14 people would arrive Monday morning.  610

The Centers for Disease Control and Prevention is set to shorten the recommended length of quarantine after exposure to someone positive for COVID-19, as the virus rages across the nation.According to a senior administration official, the new guidelines, which are set to be released as soon as Tuesday evening, will allow people who have come in contact with someone infected with the virus to resume normal activity after 10 days, or 7 days if they receive a negative test result.That's down from the 14 days recommended since the onset of the pandemic.According to the Associated Press, the agency adjusted its guidance in July by shortening it from 14 days to 10.The agency presented the new guidance during a White House coronavirus task force meeting on Tuesday for final approval, the AP reported. 812

The CDC announced Friday a pilot project intended on decreasing chronic diseases in high-risk communities. The government is putting million toward the project to address five areas of social detriments.Some groups—including racial and ethnic minorities, those living in poverty, and people in certain parts of the country—are disproportionately impacted by the burden of chronic conditions, the CDC said.“Chronic diseases touch every American, in one way or another,” said Karen Hacker, M.D., M.P.H., director of CDC’s NCCDPHP. “This important pilot project will help us better understand strategies to advance health equity and reduce the immense burden of chronic disease.”The program will address five areas on concern, said the CDC:Built environment: human-made surroundings that influence overall community health and individual behaviors that drive healthCommunity-clinical linkages: connections made among health care systems and services, public health agencies, and community-based organizations to improve population healthFood insecurity: an economic and social condition characterized by limited or uncertain access to adequate and nutritious foodSocial connectedness: the degree to which individuals or groups of individuals have and perceive a desired number, quality, and diversity of relationships that create a sense of belonging and being cared for, valued, and supportedTobacco-free policy: population-based preventive measures to reduce tobacco use and tobacco-related morbidity and mortality.The CDC said it will work with the Association of State and Territorial Health Officials and the National Association of County and City Health Officials to identify community to join the pilot program. 1727

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 FDA has given the final go-ahead to Pfizer-BioNTech's coronavirus vaccine.Shots will begin in a few days after the decision, but initial doses will be scare and rationed to health workers and nursing home residents and staff first. Enough vaccinations for the general population isn't expected until spring, prompting experts to urge the public to continue using face coverings and physically distance through the winter.Authorization had been expected Saturday morning, after an advisory panel recommended approval of the vaccine Thursday evening. According to reports, the agency was working to move it up to Friday evening.Friday morning, President Donald Trump lashed out at the Food and Drug Administration and its commissioner, Dr. Stephen Hahn, for not moving faster. Trump tweeted the FDA “is still a big, old, slow turtle. Get the dam vaccines out NOW, Dr. Hahn @SteveFDA. Stop playing games and start saving lives!!!” 939
