Often you will see a measurement of vacuum pressure described as an absolute pressure reading, so is there any difference between the two?
A vacuum pressure is one that is lower than the ambient environment surrounding pressure, and is typically measured relative to a perfect vacuum or full vacuum.
Since the reference pressure is not relative to another pressure and does not change, it is called the absolute reference or absolute pressure reference.

Any pressure measured relative to a full vacuum, whether above or below the surrounding ambient air pressure, is called an absolute pressure.
