A Commonwealth Fund study estimates that, through November 2022, COVID-19 vaccines prevented more than 18.5 million US hospitalizations and 3.2 million deaths and saved the country $1.15 trillion.
The modeling study estimated hospitalizations and deaths averted through the end of November 2022, at a time when 80% of the US population had received at least one dose of COVID-19 vaccine.
Approved COVID-19 vaccines have been available in the United States since December of 2020. Since Dec 12, 2020, 82 million infections, 4.8 million hospitalizations, and 798,000 deaths have been reported in the United States.
"Without vaccination the U.S. would have experienced 1.5 times more infections, 3.8 times more hospitalizations, and 4.1 times more deaths," the authors wrote. "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."

The model used in the study took into account the transition patterns seen with five variants, each with cumulative prevalence of at least 3% in the United States, including Iota, Alpha, Gamma, Delta, and Omicron, in addition to the original Wuhan-I SARS-CoV-2 strain. The model also used aged demographics to account for disease severity.
