Clear, thorough, reassuring story for people who are worried about breakthrough infections after COVID vaccinations. Even with Delta variant, vaccinated people are extremely well protected & unvaccinated people are extremely vulnerable https://t.co/IT0gCTas56 @ejwillingham @sciam

This is non randomized. The two biases are:
1. Behavior among those who got vaccinated likely different than those who don't
2. Likely those who didn't tested more aggressively
I would not cite this as many are doinghttps://t.co/rSkBC37uq0
