Which means it was going to be like this. Perhaps if everyone was vaccinated in a very short order (perhaps less than a month window)

Or if we had done a better job of lockdown in that first month. The goal was fire break, not coffee break.

3. People who are vaccinated and have gone back to life as normal need to go back to protecting themselves and others by masking up.

4. People should consider upping their mask quality; some reports say that Delta can lead to a 1000-fold increase in viral loads, so the mostly-good-enough nature of your cloth mask may now be almost-good-enough.
