The foam underlayment is almost certainly a moisture barrier also.

No, it is not.

Why do you say that? When I installed my laminate flooring the foam
pad they sold me had a plastic layer on the bottom side that was the
moisture barrier. The instructions clearly stated on how to tape the
seams together to prevent moisture emanating up from the concrete pad.
I still have some of it saved for when I do another small room.

It depends on the manufacturer/product.

Some products combine both functions (underpad and vapor
barrier) into a single sheet. But in other cases you
need to install two separate layers.

Read the actual product labels/instructions carefully to
see what you've got/need.
