Abstract

COVID-19 infections driven by the Omicron variant are sweeping across the United States. Although early evidence suggests that the Omicron variant may cause less severe disease than previous variants, the explosive spread of infections threatens to drive hospitalizations and deaths to unprecedented high levels, swamping already overburdened hospitals. Booster vaccination appears to be effective at preventing severe illness and hospitalization. However, the pace of booster vaccination in the US has been slow despite the available infrastructure to administer doses at a much higher rate.

We used an age-stratified, multi-variant agent-based model to project the reduction in COVID-related deaths and hospitalizations that could be achieved by accelerating the current daily pace of booster vaccination in the US. We found that doubling the rate of booster vaccination would prevent over 400,000 hospitalizations and 48,000 deaths. Tripling the booster vaccination rate would avert over 600,000 hospitalizations and save 70,000 lives during the first four months of 2022.
