An April study by the United Kingdom’s Office for National Statistics found that 9.8 percent of 2-to-11-year-olds and 13 percent of 12-to-16-year-olds infected with the coronavirus reported continuing symptoms five weeks later. After 12 weeks, rates remained significant: 7.4 percent in the younger group and 8.2 percent in the older group.
At any rate, and any way you look at the numbers, the risk of long covid is far worse than any data I've seen about potential complications with the vaccine.
