In this study we look at variations in rates of cervical cancer and grade-3 cervical intraepithelial neoplasia (CIN3) incidence between 2006 and 2020 in England and relate them to predictions based on the changes in HPV vaccination and cervical screening policy.  \nMethods Using population-based registry data, we estimated incidence rates and their 95% confidence intervals for cervical cancer and CIN3 by age group and by either year of diagnosis or 1-year birth cohort. Trends were compared over time and across birth cohorts by calculating relative changes with respect to reference time points. We also tested if trends in women offered HPV vaccination were significantly different across outcomes (cervical cancer and CIN3) and age groups. To do this, we used Poisson regression with adjustments for interval censoring, overdispersion and correlation between observations.  \nFindings There were 5558 cancers and 164,682 cases of CIN3 from 53.4 million women-years of observation in the age group 20–29.99 years. We found no evidence of increased cervical cancer rates over the age of 26 in cohorts not offered cervical screening until age 24.5 or 25 years. Substantial and increasing reductions in CIN3s and cervical cancers were observed in the cohorts offered HPV vaccination and were consistent with an 80%(95% CI: 72.9%– 87.1%) decrease in cervical neoplasia in the routine vaccination group.  \nInterpretation Plots against different time scales (e.g., calendar year and date ofbirth) may provide important insights that could otherwise be missed. Our findings are consistent with a sustained high effectiveness of the HPV immunization programme as the catch-up vaccination cohorts age.  \nFunding Cancer Research UK.  \nCopyright © 2024 Published by Elsevier Ltd.

The strategy relies on three key areas: (1) vaccination against human papillomavirus  \n(HPV), (2) screening and treatment of pre-cancerous lesions, and (3) treatment and palliative care.2  \nIn England, the National Health Service (NHS) has recently pledged to reach this target by 2040 and is planning to do so by boosting the uptake of both HPV vaccination and cervical screening.3 A national HPV vaccination programme has been running in England  \nThe Lancet Regional Health - Europe 2025;49: 101157  \nPublished Online xxx [https://doi.org/10](https://doi.org/10) . 1016/j.lanepe.2024 . 101157  \n*Corresponding author.  \nE-mail [address:](address: p.sasieni@qmul.ac.uk)[ p.sasieni@qmul.ac.uk](address: p.sasieni@qmul.ac.uk) (P.
