One of COVID-19's scariest mysteries is why some people are mildly ill or have no symptoms and others rapidly die — and scientists are starting to unravel why.
An international team of researchers found that in some people with severe COVID-19, the body goes rogue and attacks one of its own key immune defenses instead of fighting the coronavirus. Most were men, helping to explain why the virus is hitting men harder than women.
And separate research suggests that children fare better than adults thanks to robust “first responder” immune cells that wane with age.
They're the latest in a list of studies uncovering multiple features of the immune system's intricate cascade that can tip the scales between a good or bad outcome. Next up: Figuring out if all these new clues might offer much-needed ways to intervene.
Meanwhile, House Speaker Nancy Pelosi and Treasury Secretary Steven Mnuchin held an “extensive conversation" Wednesday on a huge COVID-19 rescue package, meeting face to face for the first time in more than a month in a last-ditch effort to seal a tentative accord on an additional round of coronavirus relief.
After a 90-minute meeting in the Capitol, Pelosi issued a statement saying the two would continue to talk. “We found areas where we are seeking further clarification," she said.
“We made a lot of progress over the last few days. We still don’t have an agreement," Mnuchin said after meeting with Pelosi and briefing top Senate Republican Mitch McConnell.
Despite the optimism, the Democratic-controlled House will vote Wednesday night on a partisan $2.2 trillion virus relief bill that is strongly opposed by Republicans.
