Modeling the impact of the difference in cross-protection data between a human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine and a human papillomavirus (HPV)-6/11/16/18 vaccine in Canada

* Women in the catch-up program are assumed to receive the same number of doses as those in the primary target population. Unless stated that a 2+1 dosing schedule is recommended, the provinces have adopted the recommended 3-dose schedule for the vaccines.
† The catch-up programs may have been initiated after the primary vaccination program began or implemented in selected school years only. For this analysis, only catch-up programs in the 2011/12 school year were modelled.
‡ In order to determine the number of women eligible for vaccination, the budget impact model calculates the number of women vaccinated since the implementation of the vaccination program in each province. Although there are expected to be 22 563 15-year olds and 22 969 16-year olds in Alberta in 2011, 10 983 and 16 849 respectively are expected to be vaccinated prior to the 2011/12 school year. Therefore, only 11 580 15-year olds and 6 120 16-year olds are eligible for the catch-up program targeting these age groups.
