Skepticism Regarding Vaccine and Gluten-Free Food Safety Among Patients with Celiac Disease and Non-celiac Gluten Sensitivity

Aims To query individuals with celiac disease (CD) and non-celiac gluten sensitivity (NCGS) on their beliefs toward the health effects of gluten, and safety of vaccines and GF food products.

Subjects with NCGS were more likely than those with CD to disagree with the statement that “vaccines are safe for people with celiac disease” (NCGS 41.3% vs. CD 26.4% ( p
