NCT ID NCT05557370
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how well the HPV9 vaccine (Gardasil 9) works in people who have had a kidney transplant. Researchers will measure antibody levels in 30 transplant recipients over 24 months and compare them to published data from healthy individuals. The goal is to see if the vaccine provides similar protection against HPV in this vulnerable group.
