Human Papillomavirus Vaccine Impact Monitoring Project Across CT (HPV-IMPACT)



This project aims to monitor the impact of human papillomavirus (HPV) vaccine on cervical cancer precursors and HPV types associated with those precursors.   

Goals & Objectives

  • Monitor HPV vaccine impact on cervical cancer precursors, cervical intraepithelial neoplasia (CIN) grade 2 and 3 and adenocarcinoma in situ (AIS).
  • Monitor HPV vaccine impact on HPV types associated with CIN 2/3 and AIS lesions.
  • Improve public health practice through local population-based surveillance of HPV-related cervical cancer precursors.   


  • Statewide passive monitoring of CIN2/3 and AIS diagnoses from pathology laboratories
  • Population-based active surveillance for CIN2/3 and AIS in New Haven county
  • Enhanced data collection to determine HPV vaccination status
  • Specimen collection to determine HPV type associated with CIN2/3 and AIS diagnoses
