Visitors are now able to enter the White House complex without having their temperatures checked for the first time since mid-March, although several other coronavirus precautions remain in place. Those who come near the president will still undergo temperature checks and testing for the virus. Over the past three months, those seeking to access the complex first had to get their temperatures checked and answer a question about whether they had experienced any symptoms associated with COVID-19. The White House says it is scaling back complex-wide temperature checks now that the District of Columbia is entering phase two of its reopening. 653

WASHINGTON — U.S. health officials have started two new studies to test various blood thinners to try to prevent strokes, heart attacks, blood clots and other complications in COVID-19 patients.Doctors increasingly are finding blood clots throughout the bodies of many people who died from COVID-19 along with signs of damage they do to kidneys, lungs, blood vessels, the heart and other organs.National Heart, Lung and Blood Institute Director Gary Gibbons says that hospitals have been giving seriously ill patients anti-clotting drugs to try to prevent this, but “quite frankly, we didn’t know how best to treat it” in terms of which drugs or doses to use and at what stage of illness.The National Institutes of Health will coordinate a study in hospitalized patients comparing low and regular doses of the blood thinner heparin. The study will involve more than 100 sites around the world participating in a research effort with various governments, drug companies, universities and others to speed coronavirus therapies.A second study in COVID-19 patients not sick enough to need hospitalization will test various strategies against placebo pills: baby aspirin or low or regular doses of the anti-clotting drug apixaban, sold as Eliquis in the United States. The goal there is preventing blood clots or hospitalization.A third study starting later will test blood thinners for people who have recovered and no longer test positive for the coronavirus. Evidence is building that they may remain at higher risk for blood clots. 1538

WASHINGTON — The Supreme Court is denying Congress access to secret grand jury testimony from special counsel Robert Mueller’s Russia investigation through the November election. The justices agreed Thursday to hear the Trump administration’s appeal of a lower court order for the material to be turned over to the Democratic-controlled House of Representatives. The high court’s action will keep the documents out of congressional hands at least until the case is resolved, which is not likely to happen before 2021. The delay is a victory for Trump, who also is mounting a court fight against congressional efforts to obtain his banking and other financial records. 675

WASHINGTON — The United States has given the final go-ahead to the nation’s first COVID-19 vaccine, marking what could be the beginning of the end of an outbreak that has killed nearly 300,000 Americans.Vaccine distribution for health care workers and nursing home residents are expected to begin in the coming days after the Food and Drug Administration on Friday authorized an emergency rollout of what promises to be a strongly protective vaccine from Pfizer and its German partner BioNTech.Initial doses are scarce and rationed as the U.S. joins Britain and several other countries in scrambling to vaccinate as many people as possible ahead of winter.It will take months of work to tamp down the coronavirus that has surged to catastrophic levels in recent weeks and claimed 1.5 million lives globally. 815
