I would not regard most people with celiac disease as immunocompromised
in the sense that people with AIDS or on chemotherapy or transplant
patients would be considered immunocompromised,  So having someone with
uncomplicated celiac disease in
the household is not a contraindication for a child to get routine
vaccinations even with live attenuated viruses. The immune defect if it
is present with regard to resistance to infections is a reflection of
hyposplenism and that sems to predispose to bacterial infections such as
pneummoccal infection.  Pneumovax may be a good idea for older celiacs
who have some evidence of hyposplenism ( seen on blood smear examination)
There may be special circumstances in which celiac disease may cause more
severe immune depression such as severe malnutrition or lymphoma. In this
situation the live viral vaccinations may need to be avoided in household
contacts
