First seen Nov 01, 2025 · Last updated Apr 29, 2026 · Updated 23 times
Summary
This study compares high-dose and standard-dose flu vaccines in adults who had a kidney, heart, or liver transplant within the past year. Organ transplant recipients often have weaker immune responses to standard flu shots. The goal is to see if a higher dose or two doses provide better protection against the flu. About 396 participants will be followed to measure antibody levels and side effects.
