A letter to the editor of this newspaper two weeks ago described mask-wearing in fully vaccinated folks as protecting the mask-wearers from unvaccinated people. That’s true, but it also protects the unvaccinated from the rare but possible spread of COVID-19 from fully vaccinated individuals (who might or might not have symptoms).
The letter writer also talked about wearing a mask since the beginning of the pandemic to keep from spreading COVID-19 in the event that she was an asymptomatic carrier, before vaccines were available. The letter writer’s behavior brought to mind what Confucius would call noble behavior — more about that shortly.
