Double-Pfizer but I still wear a mask. Several reasons: reminder to me to be careful touching my face/eyes with dirty hands, and is probably a significant factor in the low flu count last winter. If I suddenly sneeze, you won’t wear it as it’s mainly trapped in the mask. It’s a reminder to others that I’m paying attention as their wearing one reminds me. Finally, if I’m somewhere where talking loudly or yelling is required, it keeps the spittle under control. Watch any concert video up close…. Vaccines aren’t perfect. Those near me might not be vaccinated. No skin off my nose to think of others.

Edit: and I wear a multilayer mask not a disguise.
