This is a theory. Masking decreases viral inoculum--> increases asymptomatic infection. Asymptomatic infection--> strong T-cell and (memory B cell) immunity for some duration. Could masking be a crude vaccine until we get to real vaccine? . 

This is a theory. Now we need more data on 1) do asymptomatic infections in settings of masking lead to natural slowing; 2) severity of infection in places that mask/don't mask; 3) duration of T-cell immunity in symptomatic vs asymptomatic.

Totally agree with Dr. Rasmussen it is a theory and I am not suggesting pox parties as the article clearly states; just saying masking could be good on multiple levels (decrease transmission, decrease disease severity, help drive up immunity). Thanks.
