November 30, 2023 updated by: ANRS, Emerging Infectious Diseases

The Yellow Fever Vaccine Immunity in HIV Infected Patients: Studies of Immunological Responses at 10 Years (ANRS 0146s NovaaTen)

ANRS 0146s NovaaTen study aims to determine the vaccine responses in the participants of the ANRS EP46 Novaa trial 10 years after a primary anti-yellow fever vaccination

Study Overview

Status

Not yet recruiting

Detailed Description

The vaccine responses will be determined with the measurement of the neutralizing antibody titers using the neutralization tests PRNT and Pseudo type ACN 400 to M120 (ten years) in the participants of the ANRS EP 46 NOVAA trial, VIH+ and controls naïve to previous vaccination ten years after a primary anti-yellow fever vaccination.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Immuno-virologic criterion
Time Frame: At Months 120 (10years)
At Months 120 (10years), the antibody titers of neutralizers by PRNT (Plaque reduction neutralization test) and pseudotypes will be determined
At Months 120 (10years)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Predicting a sustained vaccine response 10 years later.
Time Frame: At Months 120 (10years)
To study the effect of clinical and biological factors in HIV+ patients (collection of data on: age; clinical examination; heart rate; weight; body temperature; blood pressure; CD4, CD8 and the CD4/CD8 ratio; the nadir and zenith of CD4; the duration of antiretroviral treatment; the duration of HIV infection) on the PRNT titers transformed into logarithm and the percentages of neutralization at ten years, uni and multivariate regressions are used.
At Months 120 (10years)
