WHO recommends that people, even those who ate fully vaccinated, should continue wearing masks indoors because of concerns about community spread of the virulent Delta variant. I am following that recommendation. The protection masks provide is admittedly limited, but I've noticed I touch my face and rather prominent proboscis less often when I wear them. That makes me less likely for me to infect myself or others. Plus, I'm told I'm very handsome when masked. Some have even suggested a bag.
