Immune Response of Shingrix Vaccine in People Living With HIV (> 50 y.o.) Compared to Age-matched Controls

Phase 4
Active, not recruiting
Conditions
RZV Vaccine (Shingrix ®)
Interventions
Registration Number
NCT05575830
Lead Sponsor
Calmy Alexandra
Brief Summary

The purpose of this study is to evaluate the efficacy and safety of the adjuvanted recombinant Zoster vaccine (RZV, or Shingrix®) in older people (\> 50 years) living with HIV (PLWH) compared to age-matched healthy adults over a 1-year period.

Detailed Description

This is a prospective multicentric phase IV study, aiming at evaluating the immunogenicity and safety profile of RZV in PLWH over 50 years of age (YOA) on long term antiretroviral therapy (ART) (\>10 years) compared to non-HIV age-matched adult controls to address the combined effect of aging and immunosuppression from HIV disease.

Inclusion will be stratified as follow:

HIV+ groups:

* Group 1: PLWH registered in the SHCS or ANRS CO3, \>75 YOA and under cART for more than 10 years - N=50

* Group 2: PLWH patients registered in the SHCS, aged between 60 and 75 and under cART for more than 10 years - N=50

* Group 3: PLWH patients registered in the SHCS, aged between 50 and 59 and under cART for more than 10 years - N=50

Control groups:

* Group 4: Healthy adults aged \>75 YOA- N=25

* Group 5: Healthy adults aged between 60 and 75 - N=25

* Group 6: Healthy adults aged between 50 and 59 - N=25

In addition, participants of all groups will be proposed to be included in the "Innate substudy" (target of 15 participants/group) and have two additional blood drawings 1 day after each vaccine dose to measure innate response triggered by RZV.

Participants will receive Shingrix® on Day0 and Day60; immunological response will be assessed on Day 1, Day61, Day90, Day360.

Unsolicited Adverse events of special intesrest (AESI) will be collected on Day 28, Day 60, Day90, Day360; patients reported outcomes (PROs) will be declared for one week after each vaccination.
