Concomitant HPV Vaccination and HPV Screening HPV Infection and Cervical Cancer in Sweden

This trial is studying whether offering HPV vaccination at the same time as HPV screening can help prevent cervical cancer in young Swedish women who have not been vaccinated before. You may be eligible if: you are a woman between ages 22 and 26 living in the study area; you have not opted out of the screening program; and you consent to participate. You may NOT be eligible if: you have a known severe allergy to any ingredient in the HPV vaccine (Gardasil 9); you have an immune disorder; you have a high fever or serious acute illness right now; you received blood products or immunoglobulin in the past 6 months; you are currently pregnant; or you have had a total hysterectomy (uterus and cervix removed). Talk to your doctor to see if this trial is right for you.
