The United Kingdom says it will be the first to conduct COVID-19 vaccine human challenge trials.It's different than other vaccine studies. People will be deliberately infected with the virus, which speeds up the research process.Pending approval, the process will start in January at a London hospital. It will require about 90 healthy young adults between the ages of 18 and 30.The group 1 Day Sooner has recruited from all over the world, including 3,000 Britons.“If the vaccine works, then ideally, people don't get infected and if people do, then they will be closely monitored and treated, but because these are young and healthy people taking part in the trial, I think, researchers feel comfortable doing so because the risks of death are on par with something like kidney donation for people who are young and healthy,” said Abie Rohrig with 1 Day Sooner.Before researchers test the vaccine, they'll do a characterization study. That's where volunteers are infected by getting a vaccine to determine the right amount of virus to give during the trial.Because of the risk, 1 Day Sooner is advocating for the entire process to be made public.Results could come in May. Even though that's likely after other COVID-19 vaccines are licensed, it's still important because we need billions of doses and because of the unique data human challenge trials provide.“Researchers can understand how the virus works in the human body. They can understand the biological markers of immunity. In fact, much of our understanding of other types of coronaviruses come from challenge studies that were conducted in the 1960s in Britain,” said Rohrig.Human challenge volunteers are paid and monitored for at least a year after. 1722

The wild ride on Wall Street just got crazier.The Dow dropped about 345 points, or 1.4%, on Tuesday, completely reversing a 244-point gain from early in the day. The selloff followed Monday's 670-point spike.The Nasdaq plunged nearly 3% -- wiping out nearly all of Monday's huge gains for the tech sector. The Nasdaq is now up just 1.5% on the year.Facebook, Twitter, Tesla and Nvidia all fell sharply. Netflix tumbled 6%, its biggest decline in two years."We started bleeding when large tech got hit hard," said Art Hogan, chief market strategist at B. Riley B.Investors poured money into bonds Tuesday. The 10-year Treasury yield slipped to 2.77%, the lowest since early February.But the sinking yields also narrowed the closely-watched gap between short and long-term rates, known as the yield curve."That has persistently been a signal of an economic slowdown," said Hogan. "I don't think that's the case here."A "flattening" yield curve also makes it harder for banks to make money on the difference between what they lend out and pay interest on. Bank of America, Wells Fargo and PNC fell more than 2% apiece.The-CNN-Wire 1135

The U.S. decline in cigarette smoking could be stalling while the adult vaping rate appears to be rising, according to a government report released Thursday.About 14% of U.S adults were cigarette smokers last year, the third year in a row the annual survey found that rate. But health officials said a change in the methodology make it hard to compare that to the same 14% reported for 2017 and 2018.The adult smoking rate last saw a substantial drop in 2017, when it fell from 16% the year before.The new figures from the Centers for Disease Control and Prevention mean there are more than 34 million adult smokers in the U.S.Meanwhile, about 4.5% of adults were counted as current e-cigarette users last year — about 11 million people.That rate appears to be up from 3.2% in 2018 and 2.8% in 2017. But again, officials said that comparing 2019 with earlier years is difficult because of the survey change.The CDC figures are based on responses from about 32,000 people.Health officials have long called tobacco use the nation’s leading cause of preventable disease and death.___The Associated Press Health & Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.
