For a ceiling and vented attic does it say vapor barrier or retarder.

A resonably well constucted ceiling with a properly vented attic should not have a problem with moisture coming through.

The drywall should be enough of a retarder.

However, it is not unusally to have large (and small) holes in the ceiling allowing too much moisture into the attic.

Those need to be sealled off first.

The biggest ones are often soffits in bathrooms and kitchens. Also plumbing chases.

Smaller ones are around electrical boxes, where cables goes through the top plate, and can lights.
