New results on a possible COVID-19 vaccine from Oxford University and drugmaker AstraZeneca suggest it is safe and about 70% effective.Some experts say that shows it is likely to win approval, but questions remain about how well it may help protect those over 55. That's a key concern for a vaccine that health officials hope to rely on around the world because of its low cost, availability and ease of use.Partial results from tests of the vaccine in the United Kingdom, Brazil and South Africa were published Tuesday by the medical journal Lancet.“Today, we have published the interim analysis of the Phase III trial and show that this new vaccine has a good safety record and efficacy against the coronavirus,” said Professor Andrew Pollard, Director of the Oxford Vaccine Group and Chief Investigator of the Oxford Vaccine Trial. “We are hugely grateful to our trial volunteers for working with us over the past eight months to bring us to this milestone.”Researchers claim the vaccine protected against disease in 62% of those given two full doses and in 90% of those initially given the half dose. However, independent experts have said the second group was too small — 2,741 people — to judge the possible value of that approach and more testing is needed.The interim analysis for efficacy was based on 11,636 participants accruing 131 symptomatic infections from the Phase III trials.In addition to the Oxford led program, AstraZeneca is conducting a large study in the US and globally. In total, Oxford University and AstraZeneca expect to enroll more than 60,000 participants globally.The company says it’s also making progress in manufacturing with a capacity of up to 3 billion doses of the vaccine in 2021 on a rolling basis, pending regulatory approval. The vaccine can be stored, transported and handled at normal refrigerated conditions for at least six months and administered within existing health care settings. 1940

New mandates for stores, cities and regions require many of us to wear masks in public, but researchers say it's important to treat them like a biohazard.Professor and Department Chair of Community, Environment and Policy at the University of Arizona Public Health College Kelly Reynolds said, while in public, the virus can get on the front of the mask and live on it for several days."By design, the mask could really be contaminated, so we recommend that people think of their masks as a biohazard," Reynolds said.The virus can live on surgical and N95 masks for up to seven days. Normally, they would be thrown out after one use, but a shortage in Personal Protective Equipment prevents that."You can’t just throw them in the washer machine -- that would destroy their fibers," Reynolds said. "For those (N95 and surgical), the best recommendation is to let the natural course of the virus dying off to run its course, so the recommendation is to take those masks and put them in a paper bag and wait seven days before you use them again."More commonly though, she said people in the community are wearing homemade, cloth masks, which can hold the virus for two days.She said one advantage in Arizona to clean those is the summer heat, which means leaving it in a car for at least 20 minutes."When it is 110 outside, in no time our cars will get really hot, so the coronavirus can survive in our cars for 20 minutes in up to 130 degrees and five minutes at 150 degrees, so that can be a very effective tool for decontaminating our masks," Reynolds said.She recommends removing the masks from the elastic around the ears using your pinkies. She said this is because those are the fingers you're least likely to use touching your face.After that, make sure to put it in a central location and sanitize or wash your hands."If you think about why we are wearing the mask in the first place, it is to prevent our exposure," Reynolds said. "Making sure you know how to properly care for your mask, and how to properly take it off and put it on is really important to reduce your risk of exposure."This story originally reported by Veronika Vernachio on KGUN9.com. 2169

NEWWARK, N.J. – OxyContin maker Purdue Pharma has pleaded guilty to three criminal charges and formally admitted its role in the opioid crisis.Tuesday's plea before a judge in Newark, New Jersey, is part of a larger settlement with the U.S. Department of Justice that also includes resolving civil claims.The Stamford, Connecticut-based company is to pay 5 million as part of the deal, while billion in forfeitures and penalties could be waived because of a proposed deal to resolve thousands of other lawsuits.Advocates are upset that the guilty plea applies only to the company and not executives or members of the Sackler family who own it.During Tuesday’s hearing, Purdue Pharma admitted to impeding the US.

NEW YORK (AP) — Stocks fell sharply on Wall Street Thursday as high-flying technology companies took a tumble after months of spectacular gains. The benchmark S&P 500 lost 3.5%, its biggest loss since June, and the tech-heavy Nasdaq fell 5%. Both indexes set record highs a day earlier. Apple, the most valuable U.S. company, slumped 8%. Big Tech companies have made outsize gains this year as investors bet that they would continue posting huge profits, even with many coronavirus restrictions still in place, as people spend more time online with their devices. Some worry those tech companies will be hit hard in a souring US-China relationship and any future tariffs, according to CNN. Treasury yields fell as cautious investors shifted money into bonds. 770

NEW YORK (AP) — A scientist who collected DNA from Scotland's Loch Ness suggests the lake's fabled monster might be a giant eel.Neil Gemmell from the University of Otago in New Zealand says the project found a surprisingly high amount of eel DNA in the water. He cautioned that it's not clear whether that indicates a gigantic eel or just a lot of little ones.But he said at a news conference in Scotland on Thursday that the idea of a giant eel is at least plausible.The DNA project found no evidence to support the notion that the monster is a long-necked ancient reptile called a plesiosaur (PLEE'-see-uh-sawr).Loch Ness is the largest and second deepest body of fresh water in the British Isles. 707
