That was pre-Delta. The higher the R0, the more mitigation we need to do. The question is what gets RE below zero.
At this point, with Delta's R0 and the vaccine's effectiveness, it looks like mere vaccination without masks is going to be insufficient in large groups (e.g. at a giant concert, a big play). But, since all the precautions have a multiplier, that's fine. It means we can keep doing those things as long as we take precautions while we do it and not assume vaccine = ignore COVID.
