Influenza Vaccination Strategy for Patients With Hematologic Malignancy
Comparison of Immunogenicity of Different Influenza Vaccines in Patients With Hematologic Malignancies
Asan Medical Center
60 participants
Dec 4, 2025
INTERVENTIONAL
Conditions
Summary
This randomized controlled trial evaluates and compares the immunogenicity of three different influenza vaccine formulations: high-dose trivalent (HD-IIV3), MF59-adjuvanted quadrivalent (aIIV4), and standard-dose trivalent (SD-IIV3) vaccines. The study population consists of patients with hematologic malignancies, including those undergoing autologous stem cell transplantation or CAR-T cell therapy. The primary goal is to identify which vaccine strategy elicits the most robust antibody and T cell-mediated immune responses in this severely immunocompromised population
