Shingles Vaccine or not?

Hello. I am supposed to have my first dose soon for plaque psoriasis. My perscribing dermatologist recommended a pneumonia and shingles vaccine.

I have a pneumonia vaccine, but I saw another dermatologist who's a psoriasis specialist who said I don't need the shingles vaccine because I am so young (25).

I've never had chicken pox before, which I heard can reappear as shingles if youre on immuno suppresants. (Correct if im wrong). Should I just get it? Insurance will cover because of the perscription.
