In a vacuum there is no matter. A vacuum is the absence of mass in a given volume of space, so an evacuated space has nothing material in it. There may be electromagnetic energy of some kind or another, however.
About the most perfect vacuum we know of is in intergalactic space. In that space, which is the space between galaxies, there is very little matter. Perhaps only a few atoms (and probably of hydrogen) in a given cubic meter is about all that we think is out there. But light and microwave background radiation will be present. In a partial vacuum, which is all that we are able to create, there would be a number of atoms of stuff there owing to the imperfections of our equipment.
