简要总结
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.
详细描述
- 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.

结局指标
主要结局
Humoral immune response
时间窗: 1 month, 13 months after 2nd dose
Defined as a 4-fold or greater increase in anti-VZV antibody concentration from pre-vaccination testing in seropositive subjects and a 4-fold or greater increase in anti-gE antibody concentration from the cutoff in seronegative subjects prior to vaccination.
次要结局
- Cell-mediated immunogenicity(1 month, 13 months after 2nd dose)
- Differences in humoral immune response and cell mediated immunogenecity(1 month, 13 months after 2nd dose)
- Grade 3/4 adverse events (AE)(Within 7 days (Day 0-6) after the first and second dose.)
- Any AIDS-defining disease(Within 3 months after 2nd dose)
- Increase in HIV Viral Load or decrease in CD4+ T-cell Count(1 month after 2nd dose)
- Any serious adverse events (SAEs)(Throughout the study period: Day 0~450 or termination, whichever came first)
