The White House chief of staff says President Donald Trump has tested negative for the coronavirus ahead of Thursday night’s second and final presidential debate.Mark Meadows says Trump was tested onboard Air Force One while en route to Nashville, Tennessee, and tested negative.Biden’s campaign said Thursday that he, too, was tested Thursday and tested negative.The test comes after Trump’s bout with the virus, which put him in the hospital for three nights.Both campaigns had been required to certify that their candidates and VIP guests have tested negative ahead of the debates. But Trump and the White House have repeatedly refused to say whether Trump actually was tested before participating in the first.Trump was diagnosed with the virus two days later. 772

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 U.S. Department of Agriculture (USDA) says it has identified some of the seeds that were mysteriously mailed to Americans from China.Osama El-Lissy, with the Plant Protection program of USDA's Animal and Plant Health Inspection Service, says 14 different species of seeds have been identified.The identified seeds include mustard, cabbage, morning glory, mint, sage, rosemary, lavender, hibiscus and roses, according to El-Lissy.Over the past few months, people across the country have received the seeds in unsolicited packages that appear to be coming from China.Officials are concerned that some of the seeds received in the U.S. could be invasive plant species, but the seeds identified so far appear to be harmless.Still, if you get unsolicited seeds in the mail, the USDA says you should not open the packets or plant the seeds. You’re asked to save the seeds and the package they came in, place everything in a mailing envelope, and contact your state plant regulatory official or APHIS State plant health director for instructions on where to send the package.The USDA says it’s important to evaluate the seed packages because they could carry seed born viruses or other diseases, posing a significant risk for U.S. agriculture and natural resources.“Imported vegetable or agricultural seed must meet labeling and phytosanitary requirements and be inspected by APHIS and CBP at the port of entry,” wrote the USDA in a release. “Some seeds, including citrus, corn, cotton, okra, tomato, and pepper seed, are restricted and may require an import permit, phytosanitary certificate, inspection at a USDA Plant Inspection Station, or testing to ensure any potential risks are mitigated.”While the USDA is still investigating why the seeds are being sent, officials say they don’t have any evidence that it’s anything other than an internet “brushing scam,” where sellers send unsolicited items to unsuspecting consumers and the post false reviews to boost sales.“Brushing scams involving seed packets in international mail shipments are not uncommon,” wrote the USDA in a release. “U.S. Customs and Border Protection (CBP) has intercepted similar seed shipments in recent years.” 2194
