WASHINGTON — President Donald Trump says the Food and Drug Administration has issued an emergency use authorization for convalescent plasma to treat COVID-19 patients.WATCH PRESS CONFERENCE:Trump, announcing the decision Sunday at the White House, called convalescent plasma a “powerful therapy.” He says the FDA’s action will expand access to the treatment, which is already being used. The treatment involves transferring antibodies from recovered COVID-19 patients to patients suffering from the disease.On Sunday, Trump said the administration have provided million to fund the Mayo Clinic study that studied the efficiency in patients that have the virus."Through this study, over 100,000 Americans have already enrolled to receive this treatment, and it is proven to reduce mortality by 35%," Trump said. "It's a tremendous number. The FDA, M.I.T., Harvard, and Mount Sinai Hospital have also found convalescent plasma to be a very effective method of fighting this horrible disease. Based on the science and the data, the FDA has made the independent determination that the treatment is safe and very effective."Trump also announced the administration provided up to 0 million to the American Red Cross and America's blood centers to support the collection of up to 360,000 units of plasma.Department of Health and Human Services Secretary Alex Azar said that patients with the virus who were treated within three days of being diagnoses benefited the most from the treatment."We saw about a 35% under survival in the patients who benefited most from the treatment, who were patients under 80 and not on artificial respiration," Azar said.The announcement follows days of suggestions by White House officials of politically motivated delays by the FDA in approving a vaccine and treatments for the disease caused by the coronavirus.Trump made the announcement on the eve of the Republican National Convention that will nominate him to run against Democrat Joe Biden. 1988

WASHINGTON — President Donald Trump aims to take credit for the speedy development of forthcoming coronavirus vaccines, even as his administration is coming under scrutiny for failing to lock in a chance to buy millions of additional doses of one of the leading coronavirus vaccine contenders this summer.That decision could delay the delivery of a second batch of doses until manufacturer Pfizer fulfills other international contracts.The revelation was first reported by the New York Times and later confirmed to the Associated Press by people familiar with the matter.Earlier this year, Pfizer agreed to make 100 million doses of its COVID-19 vaccine — enough to inoculate 50 million Americans — and gave the federal government the option to purchase up to five times as many doses. Then, this summer, Trump administration officials reportedly declined an offer to purchase 100 million more doses of the Pfizer vaccine.According to the Times, Pfizer must now also fulfill hefty orders from other countries — notably, an order for 200 million doses from the European Union — before making more doses for the U.S.In a statement, the Department of Health and Human Services said it was confident that Pfizer would be able to fulfill it's current 100 million dose order, and pointed to the fact that several other vaccine candidates are near approval — including one from Moderna, which could be approved by the end of th month.“We are confident that we will have 100 million doses of Pfizer’s vaccine as agreed to in our contract, and beyond that, we have five other vaccine candidates, including 100 million doses on the way from Moderna,” an HHS spokesperson said in a statement to the Times.The reports came on the eve of Trump’s plans to host a White House summit on Tuesday, aimed at celebrating the expected approval of the first vaccine later this week.At that event, Trump plans to sign an executive order aimed at prioritizing the supply of U.S. vaccines for Americans — though the order does not appear to have legal sway, according to the New York Times.Officials from President-elect Joe Biden’s transition team were not invited to Tuesday's event at the White House, despite the fact that the Biden administration will handle the bulk of the distribution work. 2281

VISTA, Calif. (KGTV) — A Fallbrook woman was convicted of negligence for killing a father of four off of Highway 395 near the Pala Mesa Resort in 2017.Sulem Garcia was on prescription medications when she veered off the road crashing into Paul Burke who was on his bicycle, blocks from his home on May 23, 2017. Garcia's lawyer argued she was exhausted from finishing her finals at Palomar College that day and had been on the prescription medications to treat depression for three years.  Garcia received the maximum sentence which was one year behind bars.RELATED: Bicyclist killed, 19-year-old driver arrested in North CountyMore than 60 of Burke's family members and friends were in the courtroom. Burke's wife Laura gave a victim impact statement saying she does not believe that Garcia is remorseful and that the sentencing was a slap on the wrist.  Burke owned and operated a custom surf shop for more than 40 years. He also worked at Costco.Burke's daughter and son both spoke at the sentencing hearing.   1051

WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds.Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts professor of environmental conservation.Wherever the common Mediterranean grass invades, including California's southern desert, fires flare up three times more often. And cheatgrass , which covers about one-third of the Intermountain West, is a big-time fire promoter, Bradley said."I would not be surprised at all if invasive grasses are playing a role in the current fires but I don't think we can attribute to them directly," Bradley said.University of Utah fire expert Phil Dennison, who wasn't part of the study but says it makes sense, said, "In a lot of ways, California was ground zero for invasive grasses. Much of California's native perennial grassland was replaced by Mediterranean annual grasses over a century ago. This study doesn't look at invasive grasses in the areas that are burning in California, but invasive grasses are contributing to the fires there."Experts say the areas burning now in California are more shrubs and grasses than forests, despite what President Donald Trump tweeted over the weekend."This is a global problem," said University of Alberta fire expert Mike Flannigan, who wasn't part of the study but said it makes sense. "I think with climate change and human assistance we are moving to a grass world. One region they should have mentioned is Hawaii where wildfires are increasing in large part due to invasive grasses."Invasive species are spreading more because of climate change as warmer weather moves into new areas, said study lead author Emily Fusco, also of the University of Massachusetts. New England and the Mid-Atlantic are seeing new invasive and more flammable grasses, Bradley said.The study in Monday's journal Proceedings of the National Academy of Sciences looks at the connections between a dozen species of invasive grasses and fires nationwide, finding fires occur more often in places with the non-native grasses. But the study did not find a link between invasive grasses and the size of the fires.Four of these species, including cheatgrass and common Mediterranean grass, are in California. These grasses get dry and then watch out, Fusco said."When you start a fire normally you want kindling," Fusco said. "The grasses are, more or less, like kindling"If someone lights a match and throws in the middle of a forest, it is unlikely a fire will start, but throw it in a field of cheatgrass "and odds are that it's going to catch," Bradley said."We are the reason that invasive species are here. We are the reason that they get spread around," Bradley said.Flanagan noted that invasive plants that are not grasses also feed the wildfire problem.While most outside experts said the study was important, wildfire expert LeRoy Westerling at the University of California, Merced said that with wildfires the size is key so this study is less valuable because it measures frequency.While size matters in forest fires, study author Bradley said mid to small size fires are the ones "in everybody's backyard" and affect people and their buildings more. 3313
