Could Your Mask Be a Kind of Vaccine Against COVID-19?

[2greys]

The world is still waiting for a safe, effective coronavirus vaccine. But new research now suggests that billions of people may already be using a crude vaccine of sorts: face masks.

The theory -- and it remains largely a theory -- is that by filtering out airborne coronavirus droplets and thereby lowering the dose of SARS-CoV-2 a person inhales, infections have much less chance of producing symptoms.

Much in the way vaccination works, an immune response would be triggered in the mask-wearer upon contact with a small amount of virus, but at a level that's not likely to cause serious illness.
