    HPV is the primary risk factor for cervical intraepithelial neoplasia (CIN) and cervical cancer, with high incidence in women aged 20-64 in England.

  • 2

    The risk of HPV infection peaks in adolescence and declines with age, but women remain at risk for new infections throughout adulthood.

  • 3

    HPV vaccination is effective in preventing CIN2+ and is available to girls aged 12-13 and through catch-up programs for those up to 25.

  • 4

    A model was developed to estimate the age of causal HPV infection leading to CIN2+ diagnosis in England, using historical screening data.

  • 5

    The study found that approximately 8% of CIN2+ cases occurred before the screening age of 25, highlighting the need for early intervention.
