A COVID-19 vaccine candidate being produced by biotech company Moderna has shown to be 94.5% effective in Phase 3 clinical trials, the company said Monday.The news means that the company is on track to request Emergency Use Authorization status for the drug in the coming weeks. The vaccine is already being mass-produced and thousands of doses will be ready to ship following authorization.Moderna's vaccine is closely tied with "Operation Warp Speed," a Trump administration program that provided nearly billion in government funding for research and support, and placed the vaccine on an FDA fast-track.On Aug. 11, the Department of Health and Human Services announced it was paying .5 billion ".5 billion in funds to support the large-scale manufacturing and delivery" for 100 million doses of Moderna's vaccine candidate.Moderna said Monday that 20 million doses of its vaccine will be available to ship by the end of 2020, and is on track to produce between 500 million and 1 billion doses in 2021.Health experts believe that a vaccine will be available to some people by the end of 2020, and will be widely available in spring 2021. Though it's unclear who specifically will qualify to receive the drug first, doses will need to be rationed for several months before vaccines are widely available.The release comes a week after Pfizer announced its own vaccine candidate was also on track for mass distribution after showing 90% effectiveness in Phase 3 trials.Moderna's announcement comes as welcome news to the U.S., where COVID-19 is currently spreading at a rate unseen since the pandemic first hit. More than 1 million people have been diagnosed with the virus in the last week, and at least 100,000 people are confirmed to have contracted the virus each day for the last 13 days. 1808

A House committee issued a scathing report Wednesday questioning whether Boeing and government regulators have recognized problems that caused two deadly 737 Max jet crashes and whether either will be willing to make significant changes to fix them.Staff members from the Transportation Committee blamed the crashes that killed 346 people on the "horrific culmination" of failed government oversight, design flaws and a lack of action at Boeing despite knowing about problems. The committee said the Max complied with FAA safety regulations even though the planes crashed in Indonesia and Ethiopia. Members say this shows a need for reforms. Boeing says it's made changes and it cooperated with House investigators. A message was left seeking comment from the FAA. 772

A federal judge agreed Monday to suspend a rule that requires women during the COVID-19 pandemic to visit a hospital, clinic or medical office to obtain an abortion pill. U.S. District Judge Theodore Chuang in Maryland ruled Monday that the “in-person requirements” for patients seeking medication abortion care impose a “substantial obstacle” to abortion patients and are likely unconstitutional under the pandemic's circumstances. The American College of Obstetricians and Gynecologists and other groups sued the U.S. Department of Health and Human Services and the U.S. Food and Drug Administration in May to challenge the rule. 639

A federal court on Thursday ordered the Environmental Protection Agency to ban a pesticide used widely in farming.The 2-1 ruling on a lawsuit brought by public health groups and state attorneys general ordered the agency "to revoke all tolerances and cancel all registrations for chlorpyrifos within 60 days."Concerns that the insecticide can harm the brain and nervous system led to the EPA banning the household use of chlorpyrifos in 2000. But the agency had allowed the chemical to continue to be used in commercial agriculture, where, some scientists say, it can be used in safe quantities. 603
