@jmcrookston A 30% reduction in symptomatic illness in the age group most likely to have asymptomatic infections is not very impressive. If anything this shows how half assed this approach is for Covid. I wouldn’t at all be surprised if it has close to no effect on covid transmission (which is fast and efficient with close interaction) and the reduced illness is from other less much less infectious aerosols that rely more on concentrating over time indoors.
