SIR Shield Immunity Model

Description: The interactive shield immunity model allows us to vary the strength of shielding and transmission rates (R0) to predict changes in (A) deaths per 100,000 individuals, (B) ICU beds per 100,000, and (C) cumulative deaths per 100,000 individuals when shield immunity measures are deployed.

Outbreak scenarios differ in transmission rates. Here we offer parameters for low or high R0 (low and high transmission rates) based on the Covid-19 transmission rates at various times during the 2020 pandemic as discussed here.
