> Really? The graphs I have seen show cases declining even before lockdowns were imposed. Likely because people were voluntarily locking down. Unless you deal with schools, there are no "bubbles" or not ones that really work. Do you send teachers into schools who are in the vulnerable group? Or do you close the schools? If you close the schools you may as well do a full lockdown because so many people will have to be at home to look after their children. The idea you can lockdown half the population by age just doesn't work because society doesn't separate itself out neatly by age.
