With the BA.2 Omicron subvariant now becoming dominant in the United States, a new study from Yale University and the Commonwealth Fund finds that the U.S. vaccination effort has profoundly curbed the COVID-19 pandemic’s toll.
The study, which updates estimates from December 2021, finds that without the U.S. vaccination effort, there would have been:
-
approximately 2.2 million additional COVID-19 deaths
-
more than 17 million additional COVID-19 hospitalizations in the U.S. by March 31, 2022
-
an additional $900 billion in health care spending.
These findings, the report says, “point to the tremendous power of vaccination to reduce disease and death from COVID-19.”
