Hepatitis B vaccine antibody response and the risk of clinical AIDS or death.
Abstract
BackgroundWhether seroresponse to a vaccine such as hepatitis B virus (HBV) vaccine can provide a measure of the functional immune status of HIV-infected persons is unknown.This study evaluated the relationship between HBV vaccine seroresponses and progression to clinical AIDS or death.Methods and findingsFrom a large HIV cohort, we evaluated those who received HBV vaccine only after HIV diagnosis and had anti-HBs determination 1-12 months after the last vaccine dose. Non-response and positive response were defined as anti-HBs ConclusionsHBV vaccine responses may have utility in assessing functional immune status and risk stratificating HIV-infected individuals, including those with CD4 count ≥ 500 cells/mm³.
