  We present a modified age-structured SIR model based on known patterns of
social contact and distancing measures within Washington, USA. We find that
population age-distribution has a significant effect on disease spread and
mortality rate, and contribute to the efficacy of age-specific contact and
treatment measures. We consider the effect of relaxing restrictions across less
vulnerable age-brackets, comparing results across selected groups of varying
population parameters. Moreover, we analyze the mitigating effects of
vaccinations and examine the effectiveness of age-targeted distributions.
Lastly, we explore how our model can applied to other states to reflect
social-distancing policy based on different parameters and metrics.
