内容摘要：Prasad said the FDA will ask all manufacturers to do new clinical trials in healthy people ages 50 to 64, randomly assigning them to get a vaccine or a placebo and tracking outcomes with special attention to severe disease, hospitalization or death. Companies might need to repeat that requirement for future vaccine approvals if there’s a large virus mutation rather than the past year’s incremental evolution. Companies are also free to test their vaccines for approval in younger adults and children, Prasad said, adding “this is a free country.”

As upsetting as that notification was, it also was part of an unprecedented move to mitigate the racial inequity. Evans is among more than 14,000 Black kidney transplant candidates so far given credit for lost waiting time, moving them up the priority list for their transplant.“I remember just reading that letter over and over again,” said Evans, 29, of Philadelphia, who shared the notice in a TikTok video to educate other patients. “How could this happen?”At issue is a once widely used test that overestimated how well Black people’s kidneys were functioning, making them look healthier than they really were — all because of an automated formula that calculated results for Black and non-Black patients differently. That race-based equation could delay diagnosis of organ failure and evaluation for a transplant,

that already make Black patients more at risk of needing a new kidney butAP correspondent Donna Warder reports that a racially biased test has kept thousands of Black patients from receiving a much-needed kidney transplant.

A few years ago, the National Kidney Foundation and American Society of Nephrology prodded laboratories to switch to race-free equations in calculating kidney function. Then the U.S. organ transplant network ordered hospitals to use only race-neutral test results in adding new patients to the kidney waiting list.

“The immediate question came up: What about the people on the list right now? You can’t just leave them behind,” said Dr. Martha Pavlakis of Boston’s Beth Israel Deaconess Medical Center and former chair of the network’s kidney committee.The Seoul Central District Court
