NCT01426243

Brief Summary

Main objective : To develop the tools for evaluation of humoral and cell-mediated immunity after Yellow Fever Vaccine (YFV) and compare virological and immune responses in HIV-positive and HIV-negative individuals who had not been given YFV before. Secondary objectives :

  • To develop and assess ELISPOT technology for yellow fever and to measure the response within 7, 14, 28, 90 and 365 days of administration of YFV in 30 HIV negative subjects and 40 HIV positive subjects (CD4 \> 350/mm3 under Highly Active Antiretroviral Therapy (HAART) for at least one year, with a viral load \< 50 copies/mL since at least 6 months) in terms of : (1) seroconversion by fluorescence, (2) cytotoxic response in ELISPOT, (3) neutralizing antibody levels in Plaque reduction neutralization test (PRNT:reference method) and a new pseudotype based method, (4) post-vaccination viremia and (5) diversity of viral quasi-species.
  • To assess the impact of YFV on the T-lymphocyte response against HIV by ELISPOT and viral load.

Outcome Measures

Primary Outcomes (6)

  • Immuno-virologic criterion

    \- At Day-7 will be determined the levels of antibodies by fluorescence.

    DAY-7

    At Day 0 will be determined titles and neutralization with Prnt pseudotypes, the ELISPOT response anti-yellow fever, viremia with quantitative analysis and nucleotide sequences on phylogenetic strains of viremia

    Day 0

  • Immuno-virologic criterion

    At Day 28 will be determined titles and neutralization with Prnt pseudotypes, the ELISPOT response anti-yellow fever, viremia with quantitative analysis (if it's positive at day7) and nucleotide sequences on phylogenetic strains of viremia

    Day 28

  • Immuno-virologic criterion

    At Month 3 will be determined fluorescence, PRNT and ELISPOT.

Study Arms (2)

Voluntary HIV positive subjects

ACTIVE COMPARATOR

40 HIV positive adults under HAART for at least one year (and stable on treatment for at least 3 months prior to enrolment), \> 350 CD4/mm3 (with half of them a nadir \< 200 CD4/mm3) and a viral load \< 50 copies/mL for at least 6 months. Patients were HCV negative or non-replicative and treated for at least 2 years with normal ALT and negative HBs antigen.

Biological: Yellow fever vaccination (STAMARIL)

HIV negative subjects

OTHER

Voluntary HIV negative subjects matched according to age (18-40 years and 40-55 years) and with HIV positive subjects, vaccinated at J0 and followed over one year

Biological: Yellow fever vaccination (STAMARIL)

Interventions
