Lockdowns aren't a solution. Focused protection isn't one either. Focused protection doesn't work. If COVID is super prevalent in the population you cannot protect the vulnerable population from it: even if isolation reduces risk by 30x, 0.5% viral prevalence jumping to 15% viral prevalence compensates for that. Because COVID mutates, you will have to do these crazy "focused" measures that can achieve &gt; 100x protection over and over again. GBD is dumb.,(reply>), The great bit is that if you come up with a method that reduces risk by (1 - 1 / R0)  * 100% and doesn't involve lockdowns, you kill the virus in a few weeks. And this is significantly less of a reduction than what focused protection needs because prevalence goes up quickly.
