Just thinking....
I don't know what the transmission rate of viruses from N95 mask wearers is; I assume it's low. Am prepared for correction, here!
But, what about, instead of 'lockdown until vaccine' (whenever that might be) mass production, fit-testing and mandatory wearing of such masks for those able to do so?
It's not a great 'new normal', but surely possibly more effective than acrylic barriers?
