Indolent Lymphoproliferative Disorders Clinical Trial
— EVACC-BOfficial title:
Evaluation of the Immune Response After Vaccination Against Hepatitis B in Patients With Indolent Lymphoproliferative Disorders With no Treatment.
The purpose of this study is to assess the seroconversion rate and the cellular immune response after vaccination against hepatitis B virus in patients with lymphoproliferative syndrome like chronic lymphocytic leukemia stade A and follicular lymphoma without of treatment criteria.
