Vacuum is not a medium. Considering waves, mechanical waves require a medium (such as air) to travel. Electromagnetic waves (such as visible light and radio waves) do not require a medium, and are the only waves (that we know of) that can travel through a vacuum. I have heard of a gravity wave, which may be a third type of wave. I don't know much about them. These would also travel through a vacuum.

The concept of vacuum is much uncertainty in physics. The most important is to define the relationship of vacuum and matter. The polarization of vacuum is inspiring effect on the relationship between vacuum and matter. The concept of matter like the concept of sound, is phenomenon named by people. The nature of matter can be described on fundamental concept of curvature space. If vacuum is considered as plat space, the vacuum is also the medium of curvature space. My paper "The postulate of vacuum as the medium of matter waves and the extension of the equivalence principle" gives a more detail information.

Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
Does light require a medium?
No. Any non-vacuum medium will attenuate light.
What can a medium travel thru?
Nothing (say a vacuum). The medium is what the sound travels through.
How does the speed of sound change in a vacuum?
sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)
Sound waves can't travel through A a solid B a liquid C an elastic material D a vacuum?
Sound waves cannot travel through a vacuum because it needs a medium and a vacuum has nothing within it that can act as a medium.
Is vacuum a medium of light?
Light can travel through vacuum, but it is not a medium.
Does light require a medium?
No. Any non-vacuum medium will attenuate light.
Why is the speed of light medium?
The speed of light is not medium: in vacuum, it is the highest speed that there can be. Hardly a definition of medium!
Which medium does sound not travel through?
Vacuum
Is speed of light in vacuum and medium same?
No, light in a medium will travel at a slower speed.
What can a medium travel thru?
Nothing (say a vacuum). The medium is what the sound travels through.
How does the speed of sound change in a vacuum?
sound can not be in a vacuum because a vacuum has no air. Sound needs a medium to travel though. :)
How does a medium (matter)affect the speed of light?
When light goes through any medium other than a vacuum, its speed is normally slower than in a vacuum.
Can silence exist in a vacuum?
Sound waves require a medium to travel through (i.e. air, water, ect.). In a vacuum no such medium exists so there can be no sound waves. So the answer is, yes, silence can and does exist in a vacuum.
What type of medium does light travels fastest?
A vacuum.
What is the speed of light in vacuum to the speed of light in medium yield?
That quotient is the refractive index of that medium.
The ratio of the speed of light in a medium to the speed of light in a vacuum is called its?
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
