Borchering et al. created models to assess the potential course of COVID-19 in the United States across four scenarios with different vaccination rates, effectiveness estimates, and quality and implementation of non-pharmaceutical interventions (NPIs). The data was collected through March 27, 2021 from the Johns Hopkins Center for Systems Science and Engineering Coronavirus Resource Center and federal databases, and they projected weekly reported cases, hospitalizations, and deaths, both nationally and by jurisdiction for April-September 2021. The expectation is that with high vaccination coverage and moderate NPI adherence, hospitalizations and deaths will likely remain low nationally, with a sharp decline in cases projected by July 1st, 2021. Lower NPI adherence could lead to substantial increases in severe COVID-19 outcomes, even with improved vaccination coverage, which could keep the United States from declining below 15,000 weekly cases through September.
