Vaccination scenarios: Potential vaccination scenarios with varying years of vaccine introduction, maximum coverage, and vaccine-derived immunity dynamics.

Scenario	Year of vaccine introduction	Maximum coverage	Durability of vaccine-derived immunity
1	Country-specific (2022–2034)	Country-specific (9–99%)	Full efficacy for 10 years
2	Country-specific (2022–2034)	Country-specific (9–99%)	Linear waning over 20 years
3	2022	50%	Full efficacy for 10 years
4	2022	50%	Linear waning over 20 years
5	Country-specific (2022–2034)	50%	Full efficacy for 10 years
6	Country-specific (2022–2034)	50%	Linear waning over 20 years
