Averted attack rates (difference between the attack rate in the non-vaccination scenario with respect to the vaccination one) by income as predicted by extended SEIR . The model takes into account different rates of vaccination uptake by subgroups of the given variable compared to the non-vaccination scenario. Epidemiological parameters: = 0.4, = 0.25, and R 0 = 2.5. Simulations start with I 0 = 5 initial infectious seeds. Results are sown as the median and IQR computed over 1000 simulations.
