From: Impact of vaccine hesitancy on secondary COVID-19 outbreaks in the US: an age-structured SIR model
Attack rate scatter plots by age. Scatter plot of attack rates during the second outbreak versus the remaining susceptible fraction for every US state. Top-left (A): 0–18 years old group. Top-right (B): 18–45 years old group. Bottom-left (C): 45–65 years old group. Bottom-right (D): over 65 years old group. Results also shown for a simulation of the epidemic for the whole country as if it were a single age-structured population (red dot). These high correlations show also the relevant role of age structure in the disease propagation
