Why Is It Taking So Long to Get a Covid Vaccine for Kids?

As kids around the country head back to school, there has been disappointing news this week for parents of children under 12. While many health experts had hoped for an early fall approval of a vaccine for young children, two of the nation’s top public health officials said it’s not going to happen. “I’ve got to be honest, I don’t see the approval for kids 5 to 11 coming much before the end of 2021,” said Dr. Francis S. Collins, director of the National Institutes of Health, on the NPR program “Morning Edition.”
