Brief 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
