COVID-19 vaccination associated with reductions in COVID-19 mortality and morbidity in the United States, and an approach to valuing these benefits
COVID-19 vaccination associated with reductions in COVID-19 mortality and morbidity in the United States, and an approach to valuing these benefits
COVID-19 vaccines have been crucial in mitigating adverse public health and economic impacts of the COVID-19 pandemic, but uptake has varied over numerous domains, including demographic and geographic factors. Using a regression model and county-level data on vaccination rates, cases, hospitalizations, and deaths, we estimate that COVID-19 vaccination was associated with reductions of 25.32 million cases, 1.38 million hospitalizations, and 213,000 deaths in the United States between December 2020 and July 2021. Our sensitivity analyses provide a range of estimates for cases (15.70 million to 27.97 million), hospitalizations (1.10 million to 1.86 million), and deaths (178,000 to 422,000). We value the health benefits of COVID-19 vaccination based on individual willingness to pay (WTP) to reduce one’s own morbidity and mortality risks. We estimate a total value of COVID-19 risk reductions attributable to vaccination ranging between $1.38 trillion and $4.49 trillion. Using the mid-point value of the willingness to pay, the total health benefits are estimated at $2.95 trillion, including reductions in deaths (mid-point $2.45 trillion; range: $1.15 trillion to $3.74 trillion), hospitalizations (midpoint: $354.14 billion; range: $165.27 billion to $539.08 billion), and cases (midpoint: $139.96 billion; range: $65.32 billion to $213.05 billion).
