I certainly intend to stay masked up post-jab(s). I think a month or so after the final dose it will be at the point where any viral load i might be spreading would be pretty much trustable to be at trivial levels, so that's my minimum duration. After that, I'll continue to follow public guidance from local health folks.
I don't mind masking up for flights/travel for a bit, or whatever, either, if it shakes out that way. If i could trade "wear a mask because it works and lots of people died" for "take off your shoes to fly because it's theater, one guy tried it 15 years ago and it didn't work", I'd do it in a heartbeat.
