In phase 1, we propose using Standard Expected Years of Life Lost (SEYLL) averted per dose of vaccine as the metric for premature death (14). SEYLL calculates life years lost compared to a standardized reference life table—that is, a person's life expectancy at each age as estimated on the basis of the lowest observed age-specific mortality rates anywhere in the world.
SEYLL has three major advantages. First, it regards all deaths as important but earlier deaths as particularly important. Thus, it integrates the aims of limiting harm and of prioritizing the least advantaged, particularly because early deaths are more frequent in low-income countries and are a proxy for being disadvantaged overall (10). Second, SEYLL incorporates equal moral concern by valuing a life saved at a given age identically across countries, regardless of preexisting conditions or differences in national life expectancy. Finally, SEYLL is a standard metric used in global burden-of-disease calculations (14).
就是按生命损失几率分疫苗，穷国医疗差死亡几率高，自然就多得。
其实就是官员决定谁能打疫苗，美国老人被灭绝。 别洗地了。 |
