ACIP and the FDA have determined that Shingrix is acceptably safe in immunocompromised individuals. Immune-mediated diseases were evaluated in six studies in five immunocompromised groups and were not increased among RZV recipients. One study in patients with hematologic cancers reported on graft-versus-host-disease among hematopoietic cell transplant recipients and did not identify an increased risk among RZV recipients. One study among kidney transplant patients reported on graft rejection and did not identify an increased risk among RZV recipients. Local and systemic grade 3 reactions (reactions that interfere with daily activities) were evaluated in six studies in five immunocompromised groups. Local grade 3 reactions occurred in 10.7% to 14.2% of RZV recipients, and systemic grade 3 reactions occurred in 9.9% to 22.3% of RZV recipients. Systemic grade 3 reactions were also reported by 6.0% to 15.5% of placebo recipients in these studies.
