Age pattern of COVID-19 mortality and potential life years saved in the United States, Chile, and Peru. A displays, in log scale, the age patterns of COVID-19 death rates (black line); the slope of all-cause death rates, normalized to intercept the COVID-19 death rate in the last age group (blue line); and the theoretical age-specific COVID-19 death rate that equalizes eYLL with the age group with the highest COVID-19 death rates (red line). B depicts the person-years saved per effective vaccination at each age based on confirmed COVID-19 deaths (black line) and on excess mortality estimates (green line).

Age group breakdown of COVID-19 death reports by country. The first age at which we find a crossover is shown in red. Squares indicate the crossover age groups at which the last age group’s remaining life expectancy was increased by 20%. This crossover marks the youngest age at which vaccination would save as many life years as vaccination in the oldest age group. Crosses represent the crossover age groups computed using excess mortality instead of official COVID-19 death counts. The code and data for replication are available at our repository at https://osf.io/qnpm7.
