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 Washington Post says Saudi Arabia's announcement about the death of contributing columnist Jamal Khashoggi is not an explanation at all, but a "coverup."And the Post is putting even more pressure on President Trump, the U.S. Congress and other countries to hold the Saudis accountable."The Saudis cannot be allowed to fabricate a face-saving solution to an atrocity that appears to have been directed by the highest levels of their government," Post publisher and CEO Fred Ryan said.Saturday's message from Ryan is the latest in a series of strong statements from the paper.Ever since Khashoggi was reported missing on October 2, the Post has been lobbying for information about his whereabouts and justice for his death in the Saudi consulate in Istanbul.The paper, which is owned by Amazon CEO Jeff Bezos, has put its full weight behind the Khashoggi case. 870

The University of Florida's football team is suspending activities following an “increase” in COVID-19 cases among members of the team, the university announced on Tuesday.The announcement comes just days after head coach Dan Mullen called on the university to open Ben Hill Griffin Stadium to a full capacity of 90,000 for the rest of the season. The state of Florida currently does not have a capacity restriction on stadiums."I know our governor passed that rule, so certainly, hopefully the university administration decides to let us pack the Swamp against LSU … 100 percent, because that crowd was a major factor in the game,” Mullen said following last Saturday’s 41-38 loss against Texas A&M. “So, I certainly hope our university administration follows the governor. The governor has passed a rule that we're allowed to pack the Swamp and have 90,000 in the Swamp to give us the home-field advantage Texas A&M had."The stadium is currently open at 20% capacity.Athletics director Scott Stricklin said the suspension was out of an “abundance of caution.”Sports Illustrated reported that the Gators had five new coronavirus cases identified on Tuesday.As of Tuesday afternoon, this Saturday’s game between Florida and LSU is still on as scheduled. 1269
