NCT ID NCT07156084
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a single dose of the 9vHPV vaccine, given to 9-11 year olds in 2019-2020, still provides protection six years later. About 300 teens (150 girls and 150 boys) will give a small blood sample to measure HPV antibodies. The goal is to understand how long one vaccine dose lasts, especially in boys, where data is limited.
