[Pre-print, not peer reviewed] In a model parametrized to US demographics and age-specific COVID-19 outcomes, vaccination with 40% coverage prioritizing healthcare workers and high-risk individuals and excluding children under 18 was shown to reduce the overall attack proportion from 7.1% to 1.6%. Vaccination also reduced adverse outcomes, with hospitalizations and deaths decreasing by 85% and 88%, respectively. Though they were accounted for in the model, the authors note that a vaccine uptake of 40% or lower would likely not eliminate the need for non-pharmaceutical interventions.
