Summary of vaccine program scenarios evaluated in the study

Scenario	Eligibility criteria	Purpose of scenario
Adult vaccination scenario	Individuals aged 15–49 years	Optimizing vaccine use and maximizing population-level impact within a feasible timeframe
Adolescent vaccination scenario	Individuals aged 10–14 years	Evaluating the potential long-term implementation strategy for a chlamydia vaccine
Adult vaccination scenario with vaccination based on the following:
• Age	Targeting individual age groups separately	Assessing the impact of targeting specific age groups and its implications for cost-effectiveness
• Sexual risk behavior	Targeting individual sexual risk groups separately	Assessing the impact of targeting specific sexual risk groups and its implications for cost-effectiveness
• Sex	Targeting either women or men exclusively	Assessing the impact of targeting specific sex and its implications for cost-effectiveness
Adult vaccination scenario with the following:
• Varied vaccine efficacy	Individuals aged 15–49 years	Evaluating vaccine impact across varying levels of vaccine efficacy
• Varied combinations of efficacy parameters	Individuals aged 15–49 years	Evaluating vaccine impact across varying combinations of vaccine efficacy parameters (${\mathit{VE}}_S$, ${\mathit{VE}}_I$, ${\mathit{VE}}_P$)
• Varied duration of vaccine protection	Individuals aged 15–49 years	Evaluating vaccine impact across varying durations of vaccine protection
• Varied vaccine coverage	Individuals aged 15–49 years	Evaluating vaccine impact across varying vaccine coverage levels
