The effect of HPV vaccination on the rate of high-grade cytology in 25-year-old women attending cervical screening in Ireland.

Introduction: Women vaccinated through the initial catch-up HPV vaccination programme (2011/12 to 2013/14) first became eligible for cervical screening in 2019 at age 25. This study aims to examine the changes in detection of HG cytology outcomes in 25-year-olds screened from 2010 to 2022 compared to population data on HPV vaccination in this group.

Methods: This was an ecological-type study.
