Background: Cervical cancer is a leading cause of death worldwide, and in Ireland it is the ninth most commonly diagnosed cancer in women. Almost 100% of these cancers are caused by human papillomavirus (HPV) infection. Two newly developed vaccines against HPV infection have become available. This study is a cost–utility analysis of the HPV vaccine in Ireland, and it compares the cost–effectiveness profiles of the two vaccines. Methods: A cost–utility analysis of the HPV vaccine in Ireland was performed using a Markov model. A cohort of screened and vaccinated women was compared with an unvaccinated screened cohort, and both cohorts were followed over their lifetimes. The model looked at uptake of services related to HPV disease in both cohorts. Outcomes were measured in quality adjusted life years (QALYs). Extensive sensitivity analysis was done. Results: For the base case analysis, the model showed that the incremental cost–effectiveness ratio (ICER) for quadrivalent HPV vaccination would be
25 349/QALY and
30 460/QALY for the bivalent vaccine. The ICER for the quadrivalent vaccine ranged from
2877 to
36 548, and for the bivalent from
3399 to
45 237. At current prices, the bivalent vaccine would need to be 22% cheaper than the quadrivalent vaccine in order to have equivalent cost effectiveness. Conclusion: HPV vaccination has the potential to be very cost effective in Ireland. The quadrivalent vaccine is more cost effective than the bivalent vaccine.
