Correlates of HBV-Specific B Cell Memory Following Vaccination in HIV-Infected Adolescents and HIV-Uninfected Adolescents: A Substudy of ATN 024 and ATN 025

An exploratory laboratory-based evaluation of cellular immune response to immunization with hepatitis B surface antigen in HIV-infected and HIV-uninfected adolescents. This sub-study of ATN 024 and ATN 025 compared cellular immune response in responders and non-responders to immunization and evaluated the relationship of these factors to the persistence of known correlates of serologic protection for the hepatitis B virus.
