text: SHINGRIX is a licensed recombinant subunit vaccine for protection against Herpes Zoster, whose risk of developing increases with decline of varicella zoster virus (VZV) specific immunity. The vaccine contains VZV gE antigen component extracted from CHO cells, which is to be reconstituted with adjuvant suspension AS01.
  Systematic reviews and meta-analyses have been conducted on the efficacy, effectiveness and safety of SHINGRIX in immunocompromised 18-49 year old patients and healthy adults aged 50 and over. These studies reported humoral and cell-mediated immunity rate ranged between 65.4 and 96.2% and 50.0%-93.0% while efficacy in patients (18-49 yo) with haematological malignancies was estimated at 87.2% (95%CI, 44.3–98.6%) up to 13 months post-vaccination with an acceptable safety profile.
