masking works...YOU USE THEM all the time yourself...the only questions are 1) which masks are being used, and 2) how well they are used...for those who don't know how to use them most effectively, you do the right thing as a medical professional and TEACH THEM...not deny their usefulness.
The NEJM study proves masking's effectiveness beyond the shadow of a doubt...and in a mandated circumstance within school environments...case closed.
