Critics Claim Commonwealth Fund Overstates COVID Vaccine Impact

Summary

Story summary

Critics say the Commonwealth Fund model inflates COVID-19 vaccine benefits by using unrealistic assumptions.
The study claimed U.S. vaccines prevented 18.5 million hospitalizations, 3.2 million deaths, 120 million infections and saved $1.15 trillion from December 2020 through November 2022.
CDC data show about 350,000 U.S. COVID deaths in 2020-2022, far below the study’s implied 3.2 million, while WHO reports just over 7 million worldwide deaths, making the estimate implausible.
