"Delta is a much more concerning variant globally, even than the other variants," said Bill Hanage, associate professor of epidemiology at Harvard T.H. Chan School of Public Health’s Center for Communicable Disease Dynamics. As vaccine access moves at a snail's pace outside of wealthier countries, "much of the world remains extraordinarily vulnerable," said William Powderly, director of the Institute for Public Health at Washington University in St. Louis.A scenic view from the South Lawn of the White House in Washington, May 10, 2024.
