Vapor barriers for soundproofing interior walls

Hi, I am still new to soundproofing and I was wondering if having a vapor barrier for soundproofing is actually effective or not. I was searching for this and I kept getting results that I shouldn't have them in interior walls? Is it because they're not effective?

I never heard of a vapor barrier being used for soundproofing. I don't see how it could help.

There's no problem with having a vapor on an outside wall, there's just no need for one on an inside wall.
It will do nothing to deaden the sound transfer.
Here's a soundproofing 101 website.

Hi tsu,
Reducing or eliminating sound transfer involves absorbing or deflecting that energy and it is heard to envision a vapor barrier doing either. An interior wall will have the additional problem that the wall is only one path. The offending sounds can travel over or under that wall as well. More details and maybe some here will have suggestions.
