Table 2. Prevalence of HPV 16/18 for women in each scenario 10, 20 and 50 years after initiation of vaccination (t = 0).

Prevalence of HPV 16/18 for women	10 years	20 years	50 years
Without vaccination	20.2%	20.2%	20.2%
Scenario 1	14.4% (−28.7%)	9.8% (−51.7%)	2.6% (−87.2%)
Scenario 2	13.7% (−32.2%)	8.31% (−58.9%)	0.85% (−95.8%)
Scenario 3	11.0% (−45.5%)	6.05% (−70.0%)	0.6% (−97.0%)
Scenario 4	10.1% (−50%)	4.69% (−76.8%)	0.09% (−99.6%)
Scenario 5	12.2% (−39.6%)	6.96% (−65.6%)	0.9% (−95.6%)

Vaccine coverage was supposed constant in each scenario. In parentheses, % of reduction in HPV prevalence compared to the case without vaccination.
