Youth who received only a single dose of the 9vHPV vaccine at the ages of 9-11 in 2019-2020 will be eligible to participate.\n\nApproximately 300 youth will take part in this study: 150 girls and 150 boys.\n\nParticipants will have to answer few questions about their health to ensure their eligibility for the study.
