They are recommending that fully vaccinated people can meet with other fully vaccinated people OR small groups of people from a single household that are low risk.

Those are very different situations from a large public setting from a standpoint of virus spread.

The travel recommendation is new to me. I didn't realize anyone was barred from domestic travel.

The CDC says vaccinated people can travel, do not need to self-quarantine, etc.

...then there isn't much risk, is there?

But that doesn't account for all the other interactions one has while moving beyond their bubble.
