@azdan99 This response is a bit late but I just found this out yesterday in an article in my email.
Shingrix OK'd For Immunocompromised Adults | MedPage Today

I had been upset that my transplant hospital, Mass General (MGH), would not yet approve the Shingrix vaccine for immunocompromised patients but apparently it had not been approved yet by the FDA!

I expect that I will hear from MGH very soon telling me that I can get it. That will be a huge relief. My sister-in-law has been feeling the effects of shingles since she first got it in March. Shingles put her in the hospital two times due to extreme pain. At this point she has even tried acupuncture. I want to get the vaccine and be less concerned about it. I realize not everyone gets an extreme case of it as my sister-in-law has, my husband has had shingles two times and both times it was just a minor nuisance that cleared up in less than a month.
