Two Years of U.S. COVID-19 Vaccines Have Prevented Millions of Hospitalizations and Deaths
From December 2020 through November 2022, we estimate that the COVID-19 vaccination program in the U.S. prevented more than 18.5 million additional hospitalizations and 3.2 million additional deaths. Without vaccination, there would have been nearly 120 million more COVID-19 infections. The vaccination program also saved the U.S. $1.15 trillion (Credible Interval: $1.10 trillion–$1.19 trillion) (data not shown) in medical costs that would otherwise have been incurred.
The estimated infections, hospitalizations, and deaths averted by vaccination are particularly striking when compared to the actual values observed during this time period. Since December 12, 2020, 82 million infections, 4.8 million hospitalizations, and 798,000 deaths have been reported in the U.S. In other words, without vaccination the U.S. would have experienced 1.5 times more infections, 3.8 times more hospitalizations, and 4.1 times more deaths. These losses would have been accompanied by more than $1 trillion in additional medical costs that were averted because of fewer infections, hospitalizations, and deaths.
