Adherence to cervical screening in the era of human papillomavirus vaccination: how low is too low?

Bauch CT, Li M, Chapman G, Galvani AP. Adherence to cervical screening in the era of human papillomavirus vaccination: how low is too low? Lancet Infect Dis 2010 Feb;10(2):133-7. PMID:20113982.

Conclusions: For a population with opportunistic screening and 30% vaccine coverage, screening rates in vaccinated women would have to decline by at least 80% (median value of probabilistic uncertainty analysis) before the incidence of cervical cancer would increase in the era since the introduction of the vaccine. By comparison, the decline needed is at least 49% in a population with organised screening and 70% vaccine coverage. In populations that have highly effective cervical screening programmes, incidence of cervical cancer starts to increase after smaller, but still substantial, decreases in screening. Introduction of vaccine is unlikely to lead to an increased incidence of cervical cancer as a result of diminished screening
