I think what people are more interested in is whether people who are dutiful with covid pre-cautions actually work(kids are a tough cohort). I think we know the answer there too.
For example, a systematic review of professionals in a workplace with mask policies versus those without.
Or systematic reviews on other helpful topics like ventilation, filtration, and testing from different cohort perspectives like kids and adults.
The current consensus we all have today is just "don't get infected" which does humanity very little good. There are evidence-based approaches that need to inform public policy makers and for those policy makers to be very clear with the public on what the risk each person entails without pre-cautions.
