Brief Summary

The National Vaccination Program, updated by the Ministry of Health in 2021, provides a new vaccination opportunity for frail patients against Herpes zoster virus (HZ). The new treatment option, on the other hand, is designed by combining VZV-specific antigen (gE) with an adjuvant system (AS01B) to induce antigen-specific cellular and humoral immune responses in individuals with preexisting immunity to VZV. Efficacy, assessed in people given two doses 2 months apart, is around 97% in those aged 50 years and 91% in those over 70 years. In the studies conducted, HZ-related hospitalizations were significantly reduced. The vaccine schedule calls for the administration of two doses 2 months apart. The current HZ Vaccination Program implemented at the regional level recommends its active and free offer in people from 18 years of age with congenital and/or acquired immunodepression, through a collaborative relationship involving, on the one hand, multispecialist and multiprofessional medical staff and, on the other hand, citizens called to play a role that is no longer passive but the subject of empowerment by consciously making their own health choices. The collaboration with ASL Roma1, in this sense, acquires value as guarantor of the supply of the adjuvanted recombinant anti-HZ vaccine and of the appropriate reporting of vaccination coverage, which to date is still far from the targets set by the PNPV'17-'19 in adults at risk for disease. The purpose of this study Single-center prospective longitudinal observational cohort study is to verify patients' compliance with the proposed vaccination, the effectiveness of counseling carried out by a multidisciplinary team in the hospital setting.

    Patients' compliance with the vaccination proposal, in terms of the number of patients vaccinated compared with the total number of subjects eligible for vaccination and afferent to the participating OUs in the project

    12 months

Study Arms (1)

Fragile patients vaccinated with herpes zoster vaccine

Patients with immunodeficiency and/or immunosuppression afferent to the U.O.C. Rheumatology, U.O.C. Hematology and Hematopoietic Stem Cell Transplantation, U.O.C. Infectious Diseases and Geriatric Internal Medicine, Travel Clinic and Occupational Health Outpatient Clinic of FPU Agostino Gemelli IRCCS who meet the inclusion criteria will be recruited. Inclusion Criteria. * Patients with congenital and/or acquired immunodepression; * Age \> 18 years; * Signature of informed consent Exclusion criteria. * Persons younger than 18 years of age

Biological: Herpes Zoster adjuvanted recombinant vaccine

Interventions

Sampling MethodNon-Probability Sample
Study Population

Since this is a large-scale observational real-life study, and given the purely exploratory primary endpoint, formal sample sizing is not necessary. However, based on the data available from the referral departments for the past year, it is estimated to include, among the immunocompromised subjects covered by the recommendation to the anti-HZ vaccine campaign: 50 HIV+ patients, 50 onco-hematology subjects, 50 immunocompromised rheumatology subjects, 50 frail geriatric patients, and 50 patients from the Travel Clinic and Occupational Health Outpatient Clinic for a total of 250 patients. These numbers may be higher or lower depending on the supply of vaccine doses by ASL Roma 1.

You may qualify if:

  • Patients with congenital and/or acquired immunodepression;
  • Age \> 18 years;
  • Signature of informed consent

You may not qualify if:

  • Persons younger than 18 years of age
  • Pregnancy and lactation
  • Hypersensitivity to the active ingredients and excipients in the formulation
  • Refusal to sign informed consent
