Clinical Trial Summary

The purpose of this study is to compare the immunogenicity and safety of recombinant zoster vaccine according to CD4+ T-cell count and age in people living with HIV, and to provide evidence to guide immunization of people living with HIV.


Clinical Trial Description

- HIV-infected individuals willing to receive recombinant zoster vaccine will be recruited at three study hospitals. - Participants are divided into two groups based on HIV status and CD4+ T cell count (HIV #1: CD4+ T cell count <300 cells/µL, HIV #2: CD4+ T cell count≥300 cells/µL, non-HIV). - Target numbers are 50 for each group. - Give 2 intramuscular doses of recombinant zoster vaccine 2 months apart. - Contact by phone on days 3 and 7 after each dose to assess for adverse events. - Evaluate immunogenicity at 1 month and 13 months after the second dose and safety. - An interim analysis is planned after the first approximately 30 participants of HIV group and 10 participants of non-HIV group complete a visit 13 months after 2nd dose. - Evaluation for the safety is planned after the first approximately 10 participants of the HIV #2 arm complete a visit 13 months after 2nd dose. ;
