Summary

This study looks at whether a single dose of the HPV vaccine still protects against the virus six years later. About 300 teens who got one shot in 2019-2020 will give a blood sample to measure antibody levels. The goal is to understand how long the immune response lasts, especially in boys, where data is limited.
