Doesn't seem necessary to have full lockdowns again (not that I ever really considered what we did a "lockdown"). I think we still need to be careful though. Not everyone has had a chance to get fully vaccinated (kids) yet, or get boosters. We vaccinated people can still spread it a bit, in addition to that unvaxxed minority of spreaders.... At some point we have to consider things "normal" again though. Perhaps when everyone has been fully vaccinated, or at least given that opportunity? That's coming pretty soon...
I have no issues with being extra vigilant still - masking, etc. - especially in crowded places. I'm good with restricting things to vaccinated people as well.
