Immune Memory After Papillomavirus Vaccination

Emory University203 enrolled

Overview

Vaccines for human papillomavirus (HPV) have been available in the United States since 2006. Early studies have shown a high rate of effectiveness of these vaccines, however it is not known how long this protection will last. The IMAP study will look at various parts of the immune system and potential markers for long lived immune responses to this vaccine.

Three groups of patients will be recruited for this study. One group will be women who have completed all three vaccinations. The second group will be women who are overdue for their final vaccination. We also recruit women who have not been vaccinated previously.
