Literally everything I read about vaccine efficacy said that the metrics they tracked were about reducing the incidence of symptoms and serious disease. They didn't even test people in the clinical trials for COVID unless they started showing symptoms.

Now, certainly, some media outlets may have been irresponsibly or ignorantly misinterpreting all this and pushing the narrative that it would make everyone immune. But that's not the CDC or WHO's fault.

> There was no mention of a future need for boosters.

Not sure what that has to do with anything. Things change.

> There was a simple promise of safety, and for things to return to normal.

You must have been reading some really watered-down news, and not actually reading what public health officials were saying.
