Patients who receive bone marrow transplantation are at high risk for complications from influenza infection. It is not whether influenza vaccination protects patients who undergo a type of bone marrow transplantation called nonmyeloablative, or reduced intensity bone marrow transplantation. This study compares the response to influenza vaccination in a group of these patients to that in healthy people.
The purpose of this study is to determine whether influenza vaccination protects patients who receive a certain type of bone marrow transplantation.
