PVA glue will indeed dry in a vacuum bag. Most wood glues used for veneer pressing or lamination are indeed PVA glues and vacuum pressing is one of the best ways to get an even clamping pressure on complex or bent laminations.

PVA glue cures by eliminating moisture from the glue, and the low pressure of the vacuum will serve to accelerate the loss of moisture from the glue.

I see. I missed the _drying_ part. The moisture has to go away from the glue for it to dry. We can help here by placing a flat water absorbing material on the tape!
